This is the 33rd annual report on rare birds in the Netherlands to be published in Dutch Birding. It comprises records from 2012 as well as belated and reconsidered records, dating back to 1844, which have been evaluated by the Dutch rarities committee, the Commissie Dwaalgasten Nederlandse Avifauna (CDNA). Several 2012 reports are still under review or awaiting submission and could therefore not be included. In addition, some reports for 2011 and earlier years are still under consideration for various reasons. The increase in records entered online on internet portals such as www.waarneming.nl reveals many new details about past records. For the sake of completeness, date extensions are presented in this report.

Details included for each record are, if available: date(s); location and/or municipality (municipal divisions as on 1 January 2013); province; number of birds if more than one, plumage and sex; type of record if trapped, photographed, sound-recorded, videoed or found dead (and where specimen is stored, if known); names of up to three observers involved in finding, identifying and recording, and relevant references in the literature, which normally include (inter)national but not regional journals, and published photographs. A compilation of most rarities videoed can be found in Plomp (2013). Records from 2011 lasting into 2012 that already have been published in the 2011 report (Ovaa et al 2012) are repeated here without reference. Observations not (yet) submitted but mentioned in the 2011 report are not repeated in this report. The sequence of the records in the species accounts is from the current year backwards, with records within one year presented chronologically. Numbers after each (sub)species' name refer to the total number of individuals 1 from 1 January 1800 to 31 December 1979, 2 since 1 January 1980 but excluding 3 the current year. Taxa marked with an asterisk * are new to the Dutch list.

The following CDNA members voted on some or all of the records in this report: Rob S A van Bemmelen, Nils van Duivendijk, Dick Groenendijk (chairman), Arjan Ovaa, Willem van Rijswijk (secretary), Roy Slaterus, Arend Wassink and Rik Winters. Max Berlijn and Marcel Haas supported the committee as non-voting archivists and assisted in submitting many reports published on national and regional websites. Reports can be submitted, preferably using the electronic submission form on www.dutchavifauna.nl or filling in this form after entering a record on www.waarneming.nl. Reports can also be sent by ordinary mail to CDNA, Duinlustparkweg 98A, 2082 EG Santpoort-Zuid, the Netherlands, preferably using the online submission forms at www.dutchavifauna.nl; this online database contains all records of rare birds up to 2012 (cf Dutch Birding 34: 346, 2012). Here, also recently accepted records or rejected reports as well as reports currently under review are listed.
Decisions regarding taxonomy have been delegated to the Dutch committee for avian systematics (Commissie Systematiek Nederlandse Avifauna; CSNA), which on 1 January 2012 consisted of the following members: Arnoud B van den Berg, André J van Loon, C S (Kees) Roselaar and George Sangster (secretary).

In 2012, at least 360 species were recorded, which is a few species below the average of 363 over the last 10 years. This number may rise depending on pending reports. The only record of Bearded Vulture Gypaetus barbatus, in June 2002, was rejected after review (identification accepted but not meeting criteria for acceptance as wild bird). Two taxa were new to the Dutch list in 2012: Sooty Tern Onychoprion fuscatus and Caspian Stonechat Saxicola maurus hemprichii. With Sooty Tern added and Bearded Vulture deleted, the Dutch list now numbers 504 species. Note, however, that a record of Stejneger's Stonechat S stejnegeri on 8-23 October 2012 on Texel, Noord-Holland, is still under review; this may become another new species for the Dutch list. Other highlights for 2012 included the second Steppe Grey Shrike Lanius lahtora pallidirostris, second and third Eastern Black Redstart Phoenicurus ochruros phoenicuroides, third Bufflehead Bucephala albeola, fifth Bonaparte's Gull Chroicocephalus philadelphia, sixth and seventh Black-winged Kite Elanus caeruleus (both twitchable), sixth to eighth Baird's Sandpiper Calidris bairdii (all three twitchable), seventh Eurasian Pygmy Owl Glaucidium passerinum, eighth Lesser Spotted Eagle Aquila pomarina and Black-throated Thrush Turdus atrogularis and ninth (but only third to be seen alive and first twitchable) Thick-billed Murre Uria lomvia. In addition, 2012 was a good year for Western Bonelli's Warbler P bonelli with three records, River Warbler Locustella fluviatilis with seven, Radde's Warbler Phylloscopus schwarzi with eight and Buff-breasted Sandpiper C subruficollis with 11, and for Olive-backed Pipit Anthus hodgsoni with (at least) 19 individuals.

Systematic list of records

Ross's Goose / Ross' Gans
Anser rossii 0,12,0
2010 11-14 March, Johannes Kerkhovenpolder, Breebaartpolder and surroundings, Delfzijl, Groningen, white morph, photographed (G Kiekebos et al); 21 March to 22 May, several sites around Lauwersmeer, Dongeradeel/De Marne, Friesland/Groningen, white morph, photographed (A Borhem, T Janssen, J Bosma et al).
1988 20 January to 27 February, Wissenkerke, Noord-Beveland, and Middelplaten, Goes, Zeeland, two adults, white morph, photographed (J Tramper et al).
All reports concern date extensions for birds previously accepted for 20 January to 15 February 1988 (two individuals in Zeeland; van den Berg & Bosman 2001), for 12 March 2010 (Johannes Kerkhovenpolder) and for 23 April 2010 (Ezumakeeg, Lauwersmeer), respectively (Ovaa et al 2012). The birds in 1988 were the second and third for the Netherlands, which returned for several consecutive winters. The other birds mentioned here are considered to be the same as those seen during the winter of 2009/10 (Ovaa et al 2012).

Greenland White-fronted Goose / Groenlandse Kolgans
Anser albifrons flavirostris 14,68,3
29 January, Ferwoude, Súdwest-Fryslân, Friesland, adult, photographed (M Bot, S Bot); 10 March, Polder Maarsseveen, Stichtse Vecht, Utrecht, and 21 March, Polder Achteraf, Breukeleveen, Wijdemeren, Noord-Holland, second calendar-year, photographed (H Russer, P Koken et al); 29 December, Aetsveldsche Polder, Weesp, Noord-Holland, adult, photographed (H van Oosterhout, J Brandjes).
This taxon was annual in 2001-06 with a total of 47 individuals, including flocks of up to 10 birds. After 2006, there have only been records in 2009 (one), 2011 (one) and 2012 (three). Hybrid Anser geese and aberrant orange-billed Siberian White-fronted Geese A a albifrons may present identification challenges.

Surf Scoter / Brilzee-eend
Melanitta perspicillata 3,23,1
5 April to 17 May, Horsmeertjes and Mokbaai, Texel, Noord-Holland, adult male, photographed, videoed (P Duin et al; Dutch Birding 34: 196, plate 259, 2012); 18-21 December, Brouwersdam, Schouwen-Duiveland, Zeeland, first-winter female, photographed (P A Wolf et al; Dutch Birding 35: 60, plate 89, 2013).
The bird on Texel was presumably the same individual that stayed in this area on 10 May 2009 and from 17 April to 2 June 2010 (Ovaa et al 2011). Despite many birders visiting Texel, it was not seen in 2011.

Ring-necked Duck / Ringsnaveleend
Aythya collaris 5,30,0
16-31 January and 16-30 April, Weerribben, Steenwijkerland, Overijssel, female, photographed (J Bredenbeek, K Vledder et al).
2011 5-16 April, Weerribben, Steenwijkerland, Overijssel, female, photographed (J Bredenbeek, K Vledder, D Woets et al).
2006 7 August to 1 September, Budel-Dorplein, Cranendonck, Noord-Brabant, adult female, photographed (R G Bouwman, J-E Kikkert, R Bouwman et al).
Both records in Overijssel are considered to refer to the same bird, which returned again in 2013. The bird in Noord-Brabant is considered a returning bird earlier seen as a first-year from 22 October 2005 to 22 January 2006 (cf van der Vliet et al 2006).

Ring-necked x Tufted Duck / Ringsnaveleend x Kuifeend
Aythya collaris x fuligula 0,8,0
5 February to 19 March and 16 December to 9 February 2013, Natuurplas Breeveld and Woerden, Woerden, Utrecht, adult male, photographed (J de Bruijn, H Russer et al).
This individual is considered to be a returning bird, recorded at this location for the first time on 6 December 2007 (Ovaa et al 2009).

White-headed Duck / Witkopeend
Oxyura leucocephala 5,13,0
17 December 2011 to 24 February, Reeuwijkse Plassen, Reeuwijk, Zuid-Holland, first-winter, photographed (Dutch Birding 34: 68, plate 89, 2012); 12-19 March, Bleeke Heide, Chaam, Alphen-Chaam, Noord-Brabant, adult female, photographed (M-J van Gestel, J van Gestel et al).
The bird at Bleeke Heide is considered to be one of the two individuals that stayed at this site two years earlier, from 24 March to 2 April 2010 and on 6-9 April 2010 (Ovaa et al 2011).

Bufflehead / Buffelkopeend
Bucephala albeola 0,2,1
27 September 2011 to 26 May and 17 September to 3 May 2013, Gaatkensplas and surroundings, Barendrecht, Zuid-Holland, adult male, photographed (B de Jong, P Sintnicolaas et al); 9-23 April, Philipsdam, Schouwen-Duiveland, Zeeland, second calendar-year male, photographed, videoed (M Hoekstein, P A Wolf, M Berlijn et al).
The returning adult male stayed at Barendrecht for its ninth consecutive winter. The young male at Philipsdam may have been the same as the first-year bird that wintered in Cornwall, England (26 October 2011 to 4 March 2012), or the bird seen in Lincolnshire, England, on 27 April (Hudson & the Rarities Committee 2013). Note that the two birds in England were accepted as different birds based on differences in head markings and that they were not confidently sexed (Cornwall bird) or sexed and aged (Lincolnshire bird; Hudson & the Rarities Committee 2013).

American Wigeon / Amerikaanse Smient
Anas americana 5,57,1
29 March to 7 April, Delfzijl, Delfzijl, Groningen, adult male, photographed (G Kiekebos et al).

Blue-winged Teal / Blauwvleugeltaling
Anas discors 6,31,2
1-8 April, De Malpie, Valkenswaard, Noord-Brabant, male, photographed (A Vink, M De Vrindt, T van de Kamp); 4 May, Jaap Deensgat, Lauwersmeer, De Marne, Groningen, adult male, photographed (M Olthoff et al).

Baikal Teal / Siberische Taling
Anas formosa 8,3,0
2011 11 February, Thoornpolder, Noord-Beveland, Zeeland, male, photographed (M Hoekstein, O Boeren, P A Wolf et al; Dutch Birding 33: 148, plate 159, 2011).
This male stayed only briefly and was therefore seen by just a handful of birders. The CDNA decided that the photographs in combination with the fact the bird walked on short grass showing the legs very well was enough to establish that it was unringed.

Green-winged Teal / Amerikaanse Wintertaling
Anas carolinensis 6,50,1
6 March to 5 April, Hilversumse Bovenmeent, Hilversum, Noord-Holland, adult male, photographed (R Sinoo, H van Oosterhout et al); 29 March to 2 April, Ezumakeeg-Zuid, Dongeradeel, Friesland, adult male, photographed (B Loonen et al).
2010 16 October to 15 November, Dijkmanshuizen, Texel, Noord-Holland, adult male, photographed (P Cools, P Duin et al).
2009 9 October 2008 to 8 April, Ottersaat, Dijkmanshuizen, Wagejot and Waal en Burg, Texel, Noord-Holland, adult male in (partial) eclipse plumage, moulting to summer plumage, photographed (J D Eerdmans, P W W de Rouw et al; Dutch Birding 30: 440, plate 527, 2008).
2004 18 May, Tweede Kroon's Polder, Vlieland, Friesland, male, photographed (B van Gemerden, H Ruissen, M Bons).
The male at Ezumakeeg is considered a returning bird seen regularly in this area from at least 2009 onwards (cf Ovaa et al 2012). The report on Texel in the winter of 2008/09 concerns a date extension for a bird earlier accepted for 9 October to 25 December 2008 and 4-8 April 2009 (Ovaa et al 2009, 2010); this bird returned in October-November 2010 and again in November 2011 (cf Ovaa et al 2012)

Atlantic Great Cormorant / Grote Aalscholver
Phalacrocorax carbo carbo 7,41,-
2008 5-16 January, Hoornse Meer, Groningen, Groningen, maximum of two (on 5-6 January), second-winter, photographed (R Winters et al).
This concerns a correction of the information given in Ovaa et al (2012), in which birds were reported for this site on 5-6 and 16-30 January. This taxon is no longer considered since 1 January 2009 but the CDNA still welcomes reports from before this date.

Cory's/Scopoli's Shearwater / Kuhls/Scopoli's Pijlstormvogel
Calonectris borealis/diomedea 0,9,0
2011 9 August, Nes, Ameland, Friesland (M Olthoff).
There have been five records of Cory's C borealis, none of Scopoli's C diomedea and nine of Cory's/Scopoli's Shearwater so far. Scopoli's Shearwater has been recorded in England and Poland, so that species could also occur in Dutch waters. Cape Verde Shearwater C edwardsii has not yet been recorded in north-western European waters; however, it has reached not only the Selvagens (Fagundes et al 2012) but also Atlantic waters off North America (Patteson & Armistead 2004), so it may be a conceivable vagrant in the North Sea as well.

Squacco Heron / Ralreiger
Ardeola ralloides 25 (since 1866),57,1
27 May, Scheveningen, Den Haag, Zuid-Holland, adult summer (T den Outer).

Glossy Ibis / Zwarte Ibis
Plegadis falcinellus 116,64,-
1995 26-27 August, Holierhoekse Polder, Vlaardingen, Zuid-Holland (F van der Lans, F van der Lans, H Westerlaken et al).
This species is no longer considered since 1 January 2000 but the CDNA still welcomes reports from before this date.

Black-winged Kite / Grijze Wouw
Elanus caeruleus 1,4,2
12-13 April, Keent, Oss, and Lage Wijth, Grave, Noord-Brabant, and Loonse Waard, Wijchen, Gelderland, second calendar-year, photographed, videoed (J J F J Jansen, T Janssen, F Coenraadts et al; Jansen et al 2012; Birding World 25: 142, 2012, Dutch Birding 34: 210, plate 290, 2012); 19-20 May, Binnenveld, Rhenen, Utrecht, photographed (H de Nie, A Bos et al; Jansen et al 2012; Dutch Birding 34: 210, plate 291, 2012).
The previous twitchable Black-winged Kite stayed from 4 June to 23 August 2000 at Bargerveen, Drenthe, so this year's two were widely appreciated. Unlike a bird briefly present at Alblasserwaard, Zuid-Holland, in May 2009 and one flying over Nijmegen, Gelderland, in April 2010, both 2012 birds stayed long enough to be admired by many birders.

Griffon Vulture / Vale Gier
Gyps fulvus 9,204,7
16 June to 4 July, Sint Pietersberg, Maastricht, Limburg, second calendar-year, photographed (A Strootman, L Aandeweg et al; Dutch Birding 34: 267, plate 369, 2012); 5-7 July, Tzummarum, Franekeradeel, Friesland, four, photographed (J op den Dries et al; Dutch Birding 34: 264, plate 365, 337, plate 467, 2012); 7 July, Dwingelderveld, Westerveld, Drenthe, videoed (S Haak, L van Bergeijk, G van der Kroef et al); 7 July, Kropswolderbuitenpolder, Hoogezand-Sappemeer, Groningen (C Both); 7 July, Weerselo, Dinkelland, Overijssel, photographed (V de Lenne); 9 July, Noordbroeksterhamrik, Menterwolde, Nieuweschans, Oldambt, and Johannes Kerkhovenpolder, Delfzijl, Groningen, photographed (J Smit, A Boven et al); 9 July, Baak, Bronckhorst, Gelderland, photographed (M Schaap); 18 July, Olde Maten, Staphorst, Overijssel (G de Jong et al); 26 July, Oranje Nassau's Oord, Wageningen, Gelderland, photographed (R Middelveld); 31 July, Volkel, Uden, Noord-Brabant, second calendar-year, photographed (T Janssen et al; Dutch Birding 34: 337, plate 469, 2012); 1 August, De Kuilen, Mill, Noord-Brabant, second calendar-year, photographed (P Smeets); 3 August, Engbertsdijksvenen, Twenterand, Overijssel, second calendar-year, photographed (X Gerritsen, R Gerritsen); 8 August, Vriescheloo, Bellingwedde, Groningen, photographed (R Verstok); 9 August, Groenoord, Leiden, Zuid-Holland, photographed (W Teunissen); 10 August, Midden-Delfland, Midden-Delfland, and Voorhout, Voorhout, Zuid-Holland (M Poot, M de Graaf van Rootselaar); 18 August, De Leijen and Lankhorst, Staphorst, Overijssel, photographed (J Compagner, M Bunskoek, L van Bergeijk et al); 27 August, De Houtmaat, Hengelo, Overijssel, photographed (G ter Haar); 2 September, Lauwersoog, Dongeradeel, Friesland, and Kustweg, De Marne, Groningen, second-calendar-year, photographed (M Bot, R de Lange); 4 September, Prins Bernardweg, Schiermonnikoog, Friesland, photographed (F van Eerve, F Zwerts et al).
2011 22 May, Budel-Dorplein, Cranendonck, Noord-Brabant, two (H Vrolijk); 1 October, Almelo, Almelo, Overijssel, three, photographed (T Roeke).
2010 12 June, Den Burg, Texel, Nieuwe Haven, Den Helder, and Broekermeer, Waterland, Waterland, Noord-Holland, photographed (R E Brouwer, R Vos).
It is extremely difficult to establish the precise number of birds seen in 2012. The CDNA's conservative estimate is that seven birds were involved in the long list of sightings. The first one was present in a quarry near Maastricht, Limburg, and moved to a quarry c 5 km southward in Belgium, where it stayed until 29 July. Next, a group of four turned up near Tzummarum, Friesland, of which at least one wandered through the northern part of the country and south to Wageningen, Gelderland. The last sighting of presumably this individual was on Schiermonnikoog, Friesland, on 4 September. Probably, another one was seen on 31 July and 1 August in Noord-Brabant and, finally, one turned up in Zuid-Holland on 9-10 August. The two birds near Cranendonck on 22 May 2011 were part of a group of 17 flying past Chaam, Noord-Brabant, earlier that day (Ovaa et al 2012).

Short-toed Snake Eagle / Slangenarend
Circaetus gallicus 3,68,-
2011 7 May, Kinderdijk, Nieuw-Lekkerland, Zuid-Holland, adult, photographed (B van de Wetering, A Clements, R Slagboom et al).
2010 16 July, Leusbroekerweg, Leusden, Utrecht, photographed (R Jousma); 9 October, De Banjaard, Noord-Beveland, Zeeland, adult, photographed (M Hoekstein, I Meulmeester, N de Schipper).
The bird at Leusden in 2010 was erroneously mentioned for 2011 in the previous report (Ovaa et al 2012). The bird at De Banjaard was the same individual as the one recorded c 70 min earlier 21 km north-north-east at Ouddorp, Zuid-Holland (Ovaa et al 2012). This species is no longer considered from 1 January 2012 onwards but the CDNA still welcomes reports from before this date.

Pallid Harrier / Steppekiekendief
Circus macrourus 5,76,-
2011 10 September, Westkapelle and surroundings, Veere, Zeeland, juvenile, photographed (C Beeke, P Goedbloed et al); 17 September, Brobbelbies Noord, Landerd, Noord-Brabant, juvenile, photographed (T Janssen); 7 October, Kinderdijk, Nieuw-Lekkerland, Zuid-Holland, juvenile, photographed (J Hamelink et al); 14-16 October, Rottumerplaat, Eemsmond (M Zekhuis, M Hottinga, E Wanders et al), and 16-17 October, Rottumeroog, Eemsmond, Groningen, juvenile female, photographed (M W Kaales).
The total number accepted for 2011 is now 30. The bird at Brobbelbies Noord was seen in the municipality of Landerd, not Bernheze as mentioned in Ovaa et al (2012). The juvenile female seen on Rottumerplaat on 14-16 October was also seen on the neighbouring islet of Rottumeroog on 16-17 October (and not on 18 October as stated in Ovaa et al 2012). This species is no longer considered from 1 January 2012 onwards but the CDNA still welcomes reports from before this date.

Lesser/Greater Spotted Eagle / Schreeuwarend/Bastaardarend
Aquila pomarina/clanga 0,3,0
2011 23 April, Meijendel, Wassenaar, Zuid-Holland, and Berkheide and Vliegveld Valkenburg, Katwijk, Zuid-Holland, adult, photographed (G van der Bent, R van Rossum, R Genuït et al).
Submitted as Lesser Spotted Eagle A pomarina and most likely that species but the photographs did not show enough detail to exclude Greater Spotted Eagle A clanga or a hybrid Lesser x Greater Spotted Eagle.

Lesser Spotted Eagle / Schreeuwarend
Aquila pomarina 3,4,1
14 May, Hoog Buurlo, Apeldoorn, Gelderland, third calendar-year, photographed (A ten Hoeve; Dutch Birding 34: 197, plate 261, 2012).
This bird was photographed by just one lucky observer. Lesser Spotted Eagle remains very rare, despite breeding as nearby as north-eastern Germany and being a long-distance migrant.

Booted Eagle / Dwergarend
Aquila pennata 0,19,2
29 May, Buinerveen, Borger-Odoorn, Drenthe, dark morph (L van Welie, R Kamps); 7 June, Hoeven, Uden, Noord-Brabant, second calendar-year, pale morph, photographed (R van Rossum; Dutch Birding 34: 268, plate 372, 2012).
2011 1 May, Santpoort-Zuid, Velsen, Noord-Holland, pale morph (P A Nuyten); 7 May, Maarnsche Berg, Utrechtse Heuvelrug, Utrecht, pale morph (A Schaftenaar).
The last twitchable Booted Eagle was in June-July 2000; all records after 2000 refer to single birds flying over. The bird on 1 May 2011 is considered the same bird that was observed at several nearby sites on 30 April 2011 (Ovaa et al 2012).

Gyrfalcon / Giervalk
Falco rusticolus 4,5,0
28 October 2011 to 18 March, between Westdorpe, Terneuzen, and Maagd van Gent, Sluis, Zeeland, first-winter, grey morph, photographed, videoed (S Baeten, G De Vos, W De Rouck et al; Birding World 25: 11, 2012, Dutch Birding 34: 51, plate 54, 63, plate 77, 68, plate 88, 126, plate 174-175, 2012).
This bird (first seen past Katwijk aan Zee on 14 October 2011) was one of the crowd-pullers of the winter of 2011/12, although it roamed a very large area (including parts of neighbouring Belgium) and therefore could be difficult to pin down, sometimes not being reported for days.

Little Crake / Klein Waterhoen
Porzana parva 36,15,3
9-27 June, Beulakerpolder, De Wieden, Steenwijkerland, Overijssel, male, singing, sound-recorded (M Bunskoek, H Pohlmann, L Steen et al); 19-23 June, Arnhem, Arnhem, Gelderland, singing, photographed, sound-recorded (R Wester, J van Bruggen et al); 27-28 June, Beulakerpolder, De Wieden, Steenwijkerland, Overijssel, female, singing, sound-recorded (R Messemaker, A B van den Berg).

Baillon's Crake / Kleinst Waterhoen
Porzana pusilla 171,57,-
Justin Jansen and Gerald Oreel conducted a full revision of all reports and records of this species from 1800 to 2006 (from 2007, the species is no longer considered); the results were published in Jansen (2013). During 1976-2006, the species was considered by the CDNA but the pre-1976 records had not been revised. In the revision, 265 records were reviewed: 110 records were (re)accepted (including several breeding records) and 155 records were not accepted. The number of accepted individuals was 228 (including pulli). The monthly distribution was as follows (based on the first record date): April (one), May (26), June (35), July (11), August (17) and September (seven). From 13 breeding records, the month is unknown but it was assumed that these birds were found in May-June. The years with the highest number of individuals were: 1857 (18), 1858 (10), 1862 (six), 1898 (five), 1957 (seven), 1958 (eight), 1964 (10), 1965 (10), 1971 (11), 1975 (nine) and 2005 (17). The CDNA decided to adopt all decisions published in Jansen (2013). To avoid double use of space, we refer to this paper and the list of records (accepted and non-accepted) therein.

Little Bustard / Kleine Trap
Tetrax tetrax 32,11,1
15 January, Verdronken Land van Saeftinge, Hulst, Zeeland, photographed (A Wieland, P L Meininger et al; Dutch Birding 34: 53, plate 57, 2012).
This bird stayed for just one afternoon and was superbly photographed, resulting in the best photographs ever taken of this species in the Netherlands. It was only the third in the new millennium, after birds on 7 April 2000 and 3 September 2011; in 1980-89, five birds were accepted and, in 1990-99, four.

Great Bustard / Grote Trap
Otis tarda -,26 (since 1986),0
1987 21 March, Camperduin, Bergen, Noord-Holland (J W de Roever, M Platteeuw, W E M van der Schot et al; cf Platteeuw et al 1994).
This concerns a date correction; the record was previously published for 28 March (cf van den Berg & Bosman 2001). The bird was seen by a group of seabird migration observers when it came flying in from the North Sea.

Cream-colored Courser / Renvogel
Cursorius cursor 3,1,0
1844 c 18 October, 's-Graveland, Wijdemeren, Noord-Holland, first calendar-year, shot, skin retained at Naturalis Biodiversity Center at Leiden (via R J J Vlek; Dutch Birding 34: 356, plate 493, 2012).
This record was already mentioned in Ovaa et al (2012). Contrary to what was stated there, the original article about this record was published in the Amsterdamsche Courant on 21 October 1844. During the next week, seven other Dutch newspapers paid attention to this rare bird (Ruud Vlek in litt).

Collared Pratincole / Vorkstaartplevier
Glareola pratincola 5,18,1
23 May, Wormer- en Jisperveld, Wormerland, Noord-Holland, adult summer, photographed (R E Brouwer; Dutch Birding 34: 203, plate 270, 2012).
The bird was found by a single observer doing a bird survey in the heart of a vast marsh area, from where he could not distribute the news on time for others to see it.

Greater Sand Plover / Woestijnplevier
Charadrius leschenaultii 1,13,1
12-23 May, Punt van Reide and Dollard, Delfzijl, Groningen, second calendar-year, photographed (L Brinkhuizen, D Brinkhuizen et al; Birding World 25: 195, 2012, Dutch Birding 34: 198, plate 264, 2012).
2011 4 May, Duinen bij Falga, and 5 May, Mariëndal, Den Helder, Noord-Holland, second calendar-year female, photographed (H Bouma, C van Vliet et al; Dutch Birding 33: 272, plate 344, 2011).
The record at Den Helder in 2011 (the same individual as the one at Hoek van Holland, Zuid-Holland, on 27 April) was erroneously mentioned in Ovaa et al (2012) without date. Totals include three records of Anatolian Sand Plover C l columbinus.

American Golden Plover / Amerikaanse Goudplevier
Pluvialis dominica 1,32,4
17-18 May, Vogelpôlle, Ameland, Friesland, adult summer male, photographed (J Postma); 20 June, Slufter, Texel, Noord-Holland, adult summer, photographed (A Wassink, J van den Berg, P Duin et al); 17 July to 18 August, Schelphoek, Schouwen-Duiveland, Zeeland, adult summer male, photographed, videoed (S Lilipaly et al; Dutch Birding 34: 338, plate 472, 2012); 16-18 September, Broekerpolder, Wieringen, Hollands Kroon, Noord-Holland, adult, photographed (F Visscher, R Visscher, C Martens et al).

Pacific Golden Plover / Aziatische Goudplevier
Pluvialis fulva 9,35,5
19-24 May, Zandvoortweg, Middelburg, Zeeland, adult summer female, photographed (C Beeke, J Kolijn, T Luiten et al; Dutch Birding 34: 208, plate 288, 2012); 28 June, Westkapelle, Veere, Zeeland, adult summer male, photographed (F Arts); 3-4 July, Mariëndal, Den Helder, Noord-Holland, adult summer male, photographed (R Hovinga, H van Lierop, H Post et al; Dutch Birding 34: 338, plate 473, 2012); 8-10 July, Midden-Eierland, Texel, Noord-Holland, and 21-23 July, Slufter, Texel, Noord-Holland, maximum of two (on 21 July), adult summer, photographed, videoed (E Menkveld, R F J van Beusekom, A Wassink et al); 31 July to 1 August, Polder Waal en Burg, Texel, Noord-Holland, adult, photographed, videoed (R S A van Bemmelen, A Wassink, E Menkveld et al); 16 August, Ezumakeeg, Dongeradeel, Friesland, photographed (S Bernardus, R Olivier et al).
The reports at Westkapelle, Den Helder and Midden-Eierland, Texel (which is also assumed to be one of the two at Slufter, Texel, on 21 July) are considered to refer to the same individual because it had some missing feathers on its head, making it easily recognizable. This bird was also seen at Cley, Norfolk, England, on 22-27 June (cf Hudson & the Rarities Committee 2013).

American/Pacific Golden Plover / Amerikaanse/Aziatische Goudplevier
Pluvialis dominica/fulva 0,7,1
21 August, Prunjepolder, Schouwen-Duiveland, Zeeland, adult summer, photographed (W Janse, H Janse, K Scharroo).
This bird was submitted as American Golden Plover P dominica. It was seen in flight only, which made it impossible to distinguish safely between American and Pacific Golden Plover P fulva.

Sociable Lapwing / Steppekievit
Vanellus gregarius 12,38,1
22 June, Oostvaardersplassen, Almere, Flevoland, adult summer, photographed (M Zekhuis, H Hupkes).
2011 31 July to 22 August, Swifterbant, Dronten, and Lelystad, Flevoland, adult, photographed (R Alma, I Hagens et al; Dutch Birding 33: 350, plate 456, 2011).
The bird near Swifterbant in 2011 was not only observed in the municipality of Dronten (cf Ovaa et al 2012) but also in neighbouring Lelystad.

White-rumped Sandpiper / Bonapartes Strandloper
Calidris fuscicollis 1,36,1
28 July, Sophiapolder, Sluis, Zeeland, adult summer, photographed (P Dhaluin et al).
Remarkably, considering that there were 31 records in 2000-09, this was the first since 2009.

Baird's Sandpiper / Bairds Strandloper
Calidris bairdii 0,5,3
13-17 May, Veenoordkolk, Deventer, Overijssel, adult summer, photographed, sound-recorded, videoed (T Meijer, M W Kaales, F Meijer et al; Dutch Birding 34: 208, plate 289, 2012); 27-30 August, Noordzeestrand, Wassenaar, Zuid-Holland, juvenile, photographed, sound-recorded, videoed (F de Boer, M Veldt et al; Dutch Birding 34: 336, plate 466, 367, plate 468, 2012); 29 September, Groote Keeten, Schagen, Noord-Holland, juvenile, photographed (B van den Boogaard, L Kaaij et al; Dutch Birding 34: 417, plate 588, 2012).
The bird at Deventer constituted the first spring record. Three in one year is remarkable, as there were only five records before 2012.

Broad-billed Sandpiper / Breedbekstrandloper
Calidris falcinellus 23,93,-
2001 28 August, Breebaartpolder, Delfzijl, Groningen, adult (A Boven, B-J Prak, J J F J Jansen et al).
1990 15 May, Maasvlakte, Rotterdam, Zuid-Holland (B van Dijk).
This species is no longer considered since 1 January 2003 but the CDNA still welcomes reports from before this date.

Buff-breasted Sandpiper / Blonde Ruiter
Calidris subruficollis 3,56,11
8 May, Blije, Ferwerderadiel, Friesland, photographed (J Bosma); 31 July to 3 August, Utopia, Texel, Noord-Holland, adult, photographed, videoed (A Wassink, J van den Berg, P Duin et al; Dutch Birding 34: 338, plate 471, 2012); 12 August to 1 September, Ezumakeeg, Dongeradeel, Friesland, maximum of two (on 26 August), photographed (R Wilschut, D Klein, T de Groot et al); 17-24 August, 't Volgerland, Goedereede, Zuid-Holland, adult, photographed (G Tanis et al); 20-22 August, De Zeester, Schiermonnikoog, Friesland, adult, photographed (A van Lübeck et al); 21-22 August, Prunjepolder, Schouwen-Duiveland, Zeeland, adult, photographed (I Meulmeester et al; Dutch Birding 34: 338, plate 470, 2012); 24-30 August, between Hoorn and Oosterend, Terschelling, Friesland, adult, photographed (W van Splunder et al); 2 September, Midden-Eierland, Texel, Noord-Holland (A Wassink); 17 September to 5 October, Schakerloopolder, Tholen, Zeeland, adult, photographed (R Kraayeveld et al); 7-9 October, Buren, Ameland, Friesland, first calendar-year, photographed (M Olthoff, M Berlijn et al).
2010 24 July to 4 August, Ezumakeeg, Lauwersmeer, Dongeradeel, Friesland (M Stienstra et al), and 10-16 August, Achter de Zwarten, Lauwersmeer, De Marne, Groningen, adult, photographed (C Beeke, W-J Fontijn, R Cazemier et al).
The best year ever. The average in recent years was c five records per year. The bird at Ezumakeeg was erroneously mentioned for 2011 in last year's report (Ovaa et al 2012). It was also seen at Achter de Zwarten on the eastern side of the Lauwersmeer.

Great Snipe / Poelsnip
Gallinago media -,37,0
2010 5-6 April, Bergschenhoek, Lansingerland, Zuid-Holland (J Mudde).
The earliest spring record since 1977 (before 1 January 1977, the species was not considered); only three more were found in April, on 10 April 1999, 15 April 1998 and 30 April 1987.

Long-billed Dowitcher / Grote Grijze Snip
Limnodromus scolopaceus 0,33,2
16 September, Ezumakeeg, Dongeradeel, Friesland, first calendar-year, photographed (G Tamminga, M van der Velde); 10-11 and 18-21 November, Bantpolder, Dongeradeel, Friesland, first calendar-year, photographed (S Bernardus, R Cazemier, M Olthoff et al).
2011 15-22 May, De Blikken, Sluis, Zeeland, adult summer, photographed (J Baert, M Capello, P Dhaluin et al).
2010 13-14 May, Braakmanpolder, Terneuzen, Zeeland, adult summer, photographed (P Dhaluin, A Kind, P A Wolf et al); 28 May to 6 June, Ezumakeeg, Lauwersmeer, Dongeradeel, Friesland, adult summer, photographed (R Cazemier, K Bode et al).
Better photographs enabled to accept the dowitcher at De Blikken in 2011 as Long-billed Dowitcher L scolopaceus (earlier, it was accepted as Long-billed/Short-billed Dowitcher L scolopaceus/griseus; Ovaa et al 2012). The records at Braakmanpolder and Ezumakeeg concern date extensions for birds previously accepted for 13 May and 29 May to 6 June, respectively (Ovaa et al 2012).

Long-billed/Short-billed Dowitcher / Grote/Kleine Grijze Snip
Limnodromus scolopaceus/griseus 1,5,0
2010 28 August to 4 September, Jaap Deensgat, Lauwersmeer, De Marne, Groningen, adult, photographed (A Boven et al).
This concerns a date extension for a bird previously accepted for 28 August (Ovaa et al 2012).

Slender-billed Curlew / Dunbekwulp
Numenius tenuirostris 9,0,0
1888 5 December, Zierikzee, Schouwen-Duiveland, Zeeland, collected, photographed, skin at Missiemuseum Steijl (Jansen 2012; Dutch Birding 34: 315, plate 426, 2012).
This report was already mentioned in Ovaa et al (2012). Ruud Vlek submitted a copy of the original paper by H W de Graaf (de Graaf 1893) in which information about the date and location of this collected bird was given.

Terek Sandpiper / Terekruiter
Xenus cinereus 1,47,4
12 May, Wolfsbarge, Zuidlaardermeer, Hoogezand-Sappemeer, Groningen (W-J Fontijn); 13-18 May, Breebaartpolder, Delfzijl, Groningen, adult summer, photographed (R Cazemier, P Zuidhof et al); 27 May, Markelo, Hof van Twente, Overijssel, photographed (J Meijerink); 27-28 May, Kerkwerve, Schouwen-Duiveland, Zeeland, adult summer, photographed (B Rijksen, A Strootman et al).

Spotted Sandpiper / Amerikaanse Oeverloper
Actitis macularius 1,2,0
2011 30-31 July, Hogerwaardpolder, Rilland, Reimerswaal, Zeeland, and Woensdrecht, Noord-Brabant, adult summer, photographed, videoed (J Simons, M Krijnen et al; Krijnen et al 2011; Dutch Birding 33: 313, plate 393-394, 314, plate 395-396, 2011, 35: 359, plate 500, 2012).
This bird was not seen in the municipality of Bergen op Zoom (cf Ovaa et al 2012) but in Woensdrecht.

Greater Yellowlegs / Grote Geelpootruiter
Tringa melanoleuca 0,4,0
17 October 2010 to 7 May, several sites on Noord-Beveland, Noord-Beveland, Zeeland, second calendar-year (on arrival), photographed, sound-recorded, videoed (M Hoekstein et al; Birding World 23: 441, 2010, 24: 10, 234, 2011, Dutch Birding 32: 423, plate 598, 2010, 33: 144, plate 153, 273, plate 345, 364, plate 474, 2011, 34, 360, plate 502, 2012).
This popular bird, discovered in mid-October 2010, ended its stay on 7 May 2012, after being present for an impressively long period of almost 19 months.

Lesser Yellowlegs / Kleine Geelpootruiter
Tringa flavipes 2,23,2
5-6 May, Dijkmanshuizen, Texel, Noord-Holland, adult summer, photographed (P M A van de Wielen, A Leegwater et al; Dutch Birding 34: 203, plate 273, 2012); 23 June to 8 July, Nieuwe Keverdijkse Polder, Weesp, Noord-Holland, second calendar-year, photographed, videoed (E de Bruin, R van Dijk, H van Oosterhout et al).

Wilson's Phalarope / Grote Franjepoot
Phalaropus tricolor 6,17,1
14-19 May, Ezumakeeg, Dongeradeel, Friesland, adult summer female, photographed (J Liefting, M Stienstra, A-J Bosscher et al; Dutch Birding 34: 198, plate 263, 2012).

Bonaparte's Gull / Kleine Kokmeeuw
Chroicocephalus philadelphia 0,4,1
3 May, Razende Bol, Texel (T Zutt, R Hovinga, J van Dijk), and 4-18 June, Robbenjager and surrounding area, De Cocksdorp, Texel, Noord-Holland, first-summer, photographed, videoed (H Wien et al; Ebels & Hovinga 2012; Dutch Birding 34: 187, plate 240, 203, plate 272, 238, plate 320-321, 239, plate 322-324, 2012).
This fifth for the Netherlands was long overdue. The previous twitchable one was in February 1990 and with an individual briefly present in April 1994, not many expected that it would take 18 years before the next one would turn up. When this individual was seen off Texel on 3 May, hopes were high that it would be refound on the island itself, where it finally turned up a month later, seen by many birders during its two-week stay (Ebels & Hovinga 2012).

Ross's Gull / Ross' Meeuw
Rhodostethia rosea 1,15,0
2011 23 April, Hollands Diep near Willemstad, Moerdijk, Noord-Brabant, adult winter (J J F J Jansen, W Janse, T O V Muusse et al).
This bird was already mentioned in Ovaa et al (2012) for 21-25 April in the province of Zuid-Holland; however, on 23 April, it also foraged at the southern side of Hollands Diep in the province of Noord-Brabant.

Ring-billed Gull / Ringsnavelmeeuw
Larus delawarensis 0,8,1
23 February, Maasbracht, Maasgouw, and 7-13 March, Roosteren, Echt-Susteren, Limburg, adult, wearing colour-ring, photographed, videoed (J Nagtegaal et al; Dutch Birding 34: 132, plate 187, 2012).
This bird was wearing a red colour ring with white inscription PAA3 on its right tarsus. It turned out to be a bird trapped and ringed at Szczecin-Klucz, Zachodniopomorskie, Poland, in January 2005. This was the first recovery of this bird outside Poland. The bird was also seen across the border in Belgium in February-March (cf Dutch Birding 34: 183, plate 231, 2012).

Baltic Gull / Baltische Mantelmeeuw
Larus fuscus fuscus 0,14,2
2 May, Jan Ayeslag, Texel, Noord-Holland, adult female, wearing colour-ring, photographed (P Duin, B Loos); 4 October, Westkapelle, Veere, Zeeland, adult, wearing colour-ring, photographed (M van Kleinwee).
The adult female on Texel (with black ring with inscription J8KK on its left tarsus) had been ringed as an adult at Nordhorsvær, Sømna, Nordland, Norway, on 17 July 2005. According to Helberg et al (2009), only Baltic Gulls (and no British Lesser Black-backed Gulls L f graellsii or Scandinavian Lesser-Black-backed Gulls L f intermedius) are present in this colony. The bird at Westkapelle (with red ring with inscription C21S on its left tarsus) had been ringed as pullus near Uusikaarlepyy, Finland, on 11 June 2007.

* Sooty Tern / Bonte Stern
Onychoprion fuscatus 0,0,1
31 August, Maasvlakte, Rotterdam, Zuid-Holland, adult, photographed (B van den Broek; van den Broek & Ebels 2012; Dutch Birding 34: 303, plate 409-414, 2012).
This bird was seen and photographed by a single observer. It was flying west (out to sea) at a distance of c 300 m and could be observed for less than one minute, during which six photographs were taken. The species is a very rare vagrant in north-western Europe, mostly in summer.

Roseate Tern / Dougalls Stern
Sterna dougallii 3,32,0
2011 18-20 June, Westkapelle, Veere, Zeeland, maximum of two (on 19 June), adult summer, photographed, videoed (H Reijnhoudt, P A Wolf et al).
Although two individuals were reported, the CDNA did not receive proof that two were present and, at first, only one was accepted (Ovaa et al 2012). However, additional video footage was submitted in early 2013 that convincingly showed two individuals on 19 June.

Whiskered Tern / Witwangstern
Chlidonias hybrida 257,102,-
1995 10-16 May, Molenplaat, Bergen op Zoom, Noord-Brabant (P A Wolf, P L Meininger, S Lilipaly).
This species is no longer considered since 1 January 1996 but the CDNA still welcomes reports from before this date.

Thick-billed Murre / Kortbekzeekoet
Uria lomvia 5,3,1
28 July, Lauwersoog (M Zweemer, A Witteveen), and 29 July, Kustweg, De Marne, Groningen, adult summer, photographed, videoed (N van Duivendijk, J de Bruijn, H Zevenhuizen et al; van Duivendijk et al 2013, Zweemer et al 2012; Birding World 25: 276, 2012; 26: 24, 2013, Dutch Birding 34: 344, plate 482, 2012, 35: 101, plate 120-121, 102, plate 122, 2013), and 11-13 August, Huisduinen, Den Helder, Noord-Holland, adult summer, photographed, videoed (K Rebel, F Geldermans, M Renden et al; Zweemer et al 2012, van Duivendijk et al 2013; Dutch Birding 34: 340, plate 478, 345, plate 483, 2012; 35: 103, plate 123-124, 105, plate 127, 2013).
The ninth record but the first really twitchable bird, after an oil-stained individual seen by just a handful in February 1979 and a flyby in October 2005. Birders who did not see this individual at Lauwersoog got another chance almost two weeks later when the same bird reappeared c 130 km to the west. Unfortunately, its condition was weak and, on the last day of its stay, it was seen afloat with its head mostly under water, eventually dying and floating off (van Duivendijk et al 2013). A mid-summer appearance was most unexpected for this species.

Black Guillemot / Zwarte Zeekoet
Cepphus grylle 31,63,-
1992 25 September and 7-10 October, Egmond aan Zee, Bergen, and 10, 11 and 13 October and 18-25 October, Camperduin, Bergen, Noord-Holland, first-winter (N F van de Ham, L Stegeman, K J Eigenhuis et al).
1982 13-31 December 1981, Brouwersdam, Goedereede, Zuid-Holland, and 14 January, Middelplaat, Brouwersdam, Schouwen-Duiveland, Zeeland, adult winter (H de Jongh).
These are date extensions for birds mentioned in earlier reports (cf van den Berg & Bosman 2001). The bird in Noord-Holland in the autumn of 1992 was also present on 11 and 13 October near Camperduin. The 1982 record concerns a date extension for a bird already accepted for 13-31 December 1981 at the Zuid-Holland side of Brouwersdam. This species is no longer considered since 1 January 2007 but the CDNA still welcomes reports from before this date.

Pale Barn Owl / Witte Kerkuil
Tyto alba alba 3,6,2
14 January, Ouwerkerk, Schouwen-Duiveland, Zeeland, ringed, photographed (R van 't Hof); 10-11 November, Leemkuilen, Haaren, Noord-Brabant, photographed (A Hamers).

Eurasian Pygmy Owl / Dwerguil
Glaucidium passerinum 0,6,1
2 August, Holwerd, Dongeradeel, Friesland, photographed (R-J van der Leij, M de Vries; Dutch Birding 34: 336, plate 465, 2012).
This bird was photographed between parked cars at the ferry harbour and had probably just arrived. After it flew off, it could not be relocated. It concerns the seventh record and the sixth for the north of the country.

Boreal Owl / Ruigpootuil
Aegolius funereus 34,25,3
25-30 May, Veluwezoom, Rheden, Gelderland, singing, sound-recorded (R Stolk, H Damen, B Rijksen et al); 3 October, Rijkerswoerd, Arnhem, Gelderland, immature, photographed (J Goed, M Goed); 30 October, Gelredome, Arnhem, Gelderland, photographed, taken into care, released late November (per R Wester).
The bird on 3 October was photographed perched on the ground in a city garden. Despite an extensive search the next day, it was not refound. The bird on 30 October was found near the soccer stadium and was brought to animal recovery centre Stichting Opvang Noach in Halle, Gelderland. It was released in good health three weeks later at an undisclosed site. The CDNA considers it another individual than the bird seen on 3 October, also in Arnhem.

Alpine Swift / Alpengierzwaluw
Apus melba 7,48,2
30 April, Berkel en Rodenrijs, Lansingerland, Zuid-Holland (J Mudde); 28 May, De Hamert, Bergen, Limburg (J-E Kikkert).
2010 6 April, Clinge, Hulst, Zeeland (J Kolijn).
The bird at Clinge was not observed on 4 April (cf Ovaa et al 2012) but on 6 April.

European Roller / Scharrelaar
Coracias garrulus 53,19,0
2011 10 July, Zuidland, Bernisse, Zuid-Holland, two, one photographed, videoed (A Buurman, W Delwel et al; Dutch Birding 33: 262, plate 324, 355, plate 464, 2011).
One of the birds was very confiding and observed by many birders. The second bird was only briefly present.

Lesser Grey Shrike / Kleine Klapekster
Lanius minor 21,20,1
14 May, Amsterdam Science Park, Amsterdam, Noord-Holland, male, photographed, videoed (F Roos, T Visbeek, F Ossendorp et al; Dutch Birding 34: 208, plate 285, 2012).
1987 18-21 June, Kobbeduinen, Schiermonnikoog, Friesland, adult (E-J Alblas).
The 1987 record concerns a date extension for a bird earlier accepted for 18 June (van den Berg & Bosman 2001).

Steppe Grey Shrike / Steppeklapekster
Lanius lahtora pallidirostris 0,1,1
27 October to 9 November, Hoornder Nieuwland and Buitendijk, Texel, Noord-Holland, first calendar-year, photographed, videoed (S van Breukelen, E Menkveld, M Plomp et al; Ottens 2012, Ebels 2013; Birding World 25: 455, 2012, Dutch Birding 34: 424, plate 602, 425, plate 603, 2012, 35: 64, plate 96, 219, plate 271, 220, plate 272, 221, plate 273-275, 222, plate 276, 2013).
The second record, also for Texel, where the first was seen on 4-23 September 1994 (Wassink 1997). Given the multiple records in north-western Europe, it was long overdue. Not surprisingly, it was admired by 100s of birders during its stay. Ebels (2013) published a survey and analysis of all European records up to 2012 (73).

Woodchat Shrike / Roodkopklauwier
Lanius senator senator -,76,-
2000 30 May, Maashorst, Landerd, Noord-Brabant, male (G van Aalst).
1999 8 May, Kunstenaarsduintjes, IJmuiden, Velsen, Noord-Holland, adult female (M Broeckaert, J Sambo).
The nominate subspecies has been considered in 1957-2003 (38 are listed for 1957-79; van den Berg & Bosman 2001) and the CDNA still welcomes reports from this period. The total excludes the two records of Balearic Woodchat Shrike L s badius (1983 and 1993) (cf Boele & van Winden 2013).

Calandra Lark / Kalanderleeuwerik
Melanocorypha calandra 0,5,0
2011 29 April, Sallandse Heuvelrug, Nijverdal, Overijssel, photographed (A Hegemann, P ten Den, H A H Jansman).
The bird was found during research on the ecology of the last (and very small) population of Black Grouse Tetrao tetrix in the Netherlands; it was seen for just 10 min.

Greater Short-toed Lark / Kortteenleeuwerik
Calandrella brachydactyla 3,42,0
2010 26 April, Prunjepolder, Schouwen-Duiveland, Zeeland (W Janse, J Janse).
This was the first blank year since 1996.

Eurasian Crag Martin / Rotszwaluw
Ptyonoprogne rupestris 0,10,0
2009 31 October, Nolledijk, Vlissingen, Zeeland (T Luiten, P Beeke, P L Meininger et al).
Late-autumn records are typical, with only one record being earlier (4 October 2010) and all other birds being present between 31 October and 12 December.

Greenish Warbler / Grauwe Fitis
Phylloscopus trochiloides 6,56,3
12 June, Heiloo, Heiloo, Noord-Holland, singing, sound-recorded (A Wijker); 12-13 June, Rottumeroog, Eemsmond, Groningen, photographed (M Bunskoek; Dutch Birding 34: 267, plate 370, 2012); 26-30 July, Terrein Bergen-Noord, Noordhollands Duinreservaat, Bergen, Noord-Holland, singing, sound-recorded (A Wijker, D Groenendijk et al).
2011 4 June, Schiermonnikoog, Schiermonnikoog, Friesland, singing, photographed (E Janssen, B Sikkema).

Pallas's Leaf Warbler / Pallas' Boszanger
Phylloscopus proregulus 9,83,-
1983 2 October, Den Haag, Zuid-Holland, photographed (M Roos, H Harmsen).
This species is no longer considered since 1 January 1997 but the CDNA still welcomes reports from before this date.

Hume's Leaf Warbler / Humes Bladkoning
Phylloscopus humei 2,38,5
9 December 2011 to 22 April and 21 December to 7 January 2013, Duinpark and Berkheide, Katwijk aan Zee, Katwijk, Zuid-Holland, photographed, videoed, sound-recorded (G Twigt, S Gobin, M Langbroek et al; Dutch Birding 34: 72, plate 97, 2012); 12-29 January, Spiegel- en Blijkpolderplas, Wijdemeren, Noord-Holland, photographed, sound-recorded (E de Bruin et al); 3-12 December 2011 and 15 March to 22 April, Volkspark, Schiedam, Zuid-Holland, photographed, sound-recorded (K Hoogteyling et al; Dutch Birding 34: 72, plate 96, 207, plate 279 and 281, 2012); 25 March to 5 April, Heerenschoolbos, Katwijk aan Zee, Katwijk, Zuid-Holland, photographed, sound-recorded, videoed (C Zuyderduyn, A W J Meijer, A van der Plas et al; Dutch Birding 34: 205, plate 277, 2012); 31 October to 5 November, Eemshaven-Oost, Eemsmond, Groningen, ringed, photographed, sound-recorded (L Tervelde, M Sandifort, P Pepers et al); 22 December to 2 January 2013, Beijum, Groningen, Groningen, photographed, sound-recorded (I Weeber, E B Ebels et al; Dutch Birding 35: 62, plate 92, 2013); 26 December to 18 January 2013, Bosjes van Poot, Den Haag, Zuid-Holland, photographed, sound-recorded (V van der Spek, R van der Vliet et al).
The two at Katwijk aan Zee were at different sites; the one at Duinpark was the first to return in consecutive winters. The best year for new birds remains 2003 with six individuals but with two long-stayers from 2011 and five new birds found in 2012, this year could equally be considered the best year ever.

Radde's Warbler / Raddes Boszanger
Phylloscopus schwarzi 2,23,8
18 October, Noordhollands Duinreservaat, Castricum, Noord-Holland, ringed, photographed (H Levering et al); 20 October, Noordhollands Duinreservaat, Castricum, Noord-Holland, ringed, photographed (Q L Slings et al; Dutch Birding 34: 420, plate 592, 2012); 20 October, Zwanenwater, Schagen, Noord-Holland, ringed, photographed (F Koning, P Spannenburg); 20 October, Vliehors, Vlieland, Friesland, photographed (G Bakker, R Halff, R de Beer et al); 20 October, Bomenland, Vlieland, Friesland, sound-recorded (R Cazemier, J Scharringa, P Lindenburg et al); 20 October, Bomenland and Vallei van Malgum, Vlieland, Friesland, photographed, sound-recorded (I Goedbloed, H Heikamp, A Linckens et al); 20-21 October, Poterslid, Vlieland, Friesland, photographed, sound-recorded (H Zevenhuizen, A de Jong, D Groenendijk et al); 23 October, Spinnenkoppenvlak, Kennemerduinen, Bloemendaal, Noord-Holland, ringed, photographed (E J Maassen, R Maaskant).
With eight records, 2012 was a record year. The multiple arrivals on 20 October are noteworthy, with a total of six and four on Vlieland alone.

Dusky Warbler / Bruine Boszanger
Phylloscopus fuscatus 1,74,-
2011 27 October, Noordhollands Duinreservaat, Castricum, Noord-Holland, sound-recorded (V Hart, S Wytema, L B Steijn et al); 2-4 November, Zwarte Pad, Katwijk aan Zee, Katwijk, Zuid-Holland, photographed, sound-recorded (A W J Meijer, R van Rossum, G van der Bent et al); 12 November, Ouddorp, Goedereede, Zuid-Holland, sound-recorded (N van Houtum, S Rijnbeek et al).
2007 24 October, Westkapelle, Veere, Zeeland, sound-recorded (J Luiten, C Beeke, P A Wolf).
These records brings the total for 2011 to 13, a record year. The CDNA no longer considers this species from 1 January 2012 but still welcomes reports from before this date.

Western Bonelli's Warbler / Bergfluiter
Phylloscopus bonelli 5,28,3
2 May, Westervoort, Westervoort, Gelderland, singing, photographed, sound-recorded (R Wester, F Wagenaar, R Stolk et al; Dutch Birding 34: 207, plate 280, 2012); 21-22 May, Grenspark De Zoom-Kalmthoutse Heide, Woensdrecht, Noord-Brabant, singing, photographed, sound-recorded (B Goyens, G Vermeersch et al); 10 June to 9 July, Veluwezoom, Rheden, Gelderland, singing, photographed, sound-recorded (B van Balen et al; Dutch Birding 34: 267, plate 368, 2012).
The only other year with three birds was 1994. The bird at Woensdrecht was also observed at Kalmthoutse Heide, Antwerpen, Belgium; it was singing exactly on the border between Belgium and the Netherlands. On 30 June, the long-staying individual at Veluwezoom was feeding young in a nest. Never during the period, two Western Bonelli's Warblers were seen, so this bird was probably paired with another Phylloscopus species, or it was feeding as a helper at a nest, of which it was not a parent.

Siberian Chiffchaff / Siberische Tjiftjaf
Phylloscopus collybita tristis -,39,-
Genetic analysis of mist-netted birds at several ringing stations at coastal sites in the Netherlands showed that this taxon was much more common than previously thought (de Knijff et al 2013). This taxon, therefore, is no longer considered by the CDNA from 1 January 2012. In addition, also earlier reports will not be considered anymore, as the strict criteria used previously would be in disparity with recently developed, less strict criteria.

Iberian Chiffchaff / Iberische Tjiftjaf
Phylloscopus ibericus 2,27,1
13-26 April, Drachten, Smallingerland, Friesland, photographed, sound-recorded (G Tuinstra, S Bot et al; Dutch Birding 34: 207, plate 283, 2012).
2011 6-28 June, Hoorn, Terschelling, Friesland, photographed, sound-recorded (D Groenendijk et al).
The record on Terschelling concerns a date extension for a bird earlier accepted for 6-24 June (Ovaa et al 2012).

Subalpine Warbler / Baardgrasmus
Sylvia cantillans 5,57,2
5-6 May, De Nollen, Den Helder, Den Helder, Noord-Holland, second-calendar-year male, photographed, sound-recorded (M Renden et al; Dutch Birding 34: 207, plate 278, 2012); 6 May, Robbenjager, De Cocksdorp, Texel, Noord-Holland, second-calendar-year female (M Bot, M Haas, P van der Luit).
2011 16-17 September, Rottumerplaat, Eemsmond, Groningen, first calendar-year or female, photographed (M Zekhuis, N de Vries, H Pohlmann; Dutch Birding 33: 422, plate 572, 2011).
The bird on Rottumerplaat was only seen on 16-17 September, not 16-19 September as reported in Ovaa et al (2012). The totals include Eastern Subalpine Warbler S c albistriata (two) and Western Subalpine Warbler S c cantillans/inornata.

River Warbler / Krekelzanger
Locustella fluviatilis 6,54,7
21-24 May, Kandelaar, Rotterdam, Zuid-Holland, singing, photographed, sound-recorded, videoed (B van den Broek, A Joon et al; Birding World 25: 196, 2012, Dutch Birding 34: 204, plate 275, 2012); 23 May, Polder Peizer- en Eeldermaden, Noordenveld, Drenthe, singing, videoed (T Mulder); 25 May, Zoutkamperplaat, Lauwersmeer, Kollumerland, Friesland, singing, sound-recorded (F-J Hoogstra); 26-27 May, Hoogeveen, Hoogeveen, Drenthe, singing, sound-recorded (F van Egmond); 28 May to 10 June, Schoonlooërveld, Midden-Drenthe, Drenthe, singing, photographed, sound-recorded (E Reinstra et al); 30 May to 11 June, Broekbos, Zeewolde, Flevoland, singing, photographed, sound-recorded (S Deuzeman, W van Manen, R Kluit); 12 August, Robbenjager, De Cocksdorp, Texel, Noord-Holland (J van den Berg, W van Rijswijk, A Wassink et al).
Two or three in one year was about the average number in recent years. A singing bird at Flevopark, Amsterdam, Noord-Holland, from 22 May to 14 June has not yet been submitted. With seven records, this was the best year ever, including a rare autumn field record. Between 2000 and 2011, numbers varied from none in 2002 to six in 2004 and 2008.

Paddyfield Warbler / Veldrietzanger
Acrocephalus agricola 1,31,1
4 September, AW-duinen, Zandvoort, Noord-Holland, first calendar-year, ringed, photographed (M Schalkwijk, P Hesselman).

Blyth's Reed Warbler / Struikrietzanger
Acrocephalus dumetorum 0,16,3
11 August, Meijendel, Wassenaar, Zuid-Holland, adult, ringed, photographed (V van der Spek, M Verrips, R van der Vliet et al; Dutch Birding 34: 341, plate 479, 2012); 21 October, Noordhollands Duinreservaat, Castricum, Noord-Holland, first calendar-year, ringed, photographed (H Levering, C S Roselaar, J Visser et al); 3, 6 and 9 November, Noordhollands Duinreservaat, Castricum, Noord-Holland, first calendar-year, ringed, photographed (L Heemskerk et al)
2011 1 October, Lange Paal, Vlieland, Friesland, first calendar-year, photographed, sound-recorded (J B Groot, W A van Splunder, J van der Laan et al; Dutch Birding 33: 422, plate 571, 2011).
2010 1 October, Noordhollands Duinreservaat, Castricum, Noord-Holland, first calendar-year, ringed, photographed (Dutch Birding 32: 436, 2010; A J Wijker, Q L Slings, C S Roselaar).
The best year ever. Most individuals of this species are ringed, and Castricum is by far the best place to trap it, with eight of the 19 birds in mist-nets. October is the best month with eight records; the second bird at Castricum in 2012 was the first November record. The 2011 record on Vlieland was a bird observed in the field and not trapped but, thanks to good photographs and sound-recordings, it was readily accepted. A bird ringed at Eemshaven, Groningen, on 6 May 2011 and published as Blyth's Reed Warbler (Dutch Birding 33, 275, plate 495, 2011) was not accepted.

Wallcreeper / Rotskruiper
Tichodroma muraria 0,2,0
6 March, ENCI-groeve, Pietersberg, Maastricht, Limburg, photographed (N Rensen, W Schep, F Oling et al; Dutch Birding 34: 118, plate 160, 2012).
In 2010, one stayed here from 22 November to 11 December (Ovaa et al 2011), and it was seen again by a few lucky birders on only one day in March 2012. It is considered to be the same bird, as consecutive returns to sites away from the regular wintering areas are well known for this species. The lack of more reports in the winter of 2011/12 may be explained by the fact that this is a large and mostly inaccessible quarry, where it may be very difficult to (re)find such a small bird.

White's Thrush / Goudlijster
Zoothera aurea 11,7,0
1952 c 19 (18, 19 or 20) November, Den Burg, Texel, Noord-Holland, male, found dead (specimen retained at Ecomare, De Koog, Texel), photographed (per P Duin).
This record was listed in van den Berg & Bosman (2001) for 9 April 1953 but research by Pieter Duin revealed a report of this bird in the local newspaper (Texelse Courant) of 22 November 1952, stating that the bird had been found dead a few days before; the bird was mounted in April 1953.

Black-throated Thrush / Zwartkeellijster
Turdus atrogularis 0,7,1
11 November, Katwijk aan Zee, Katwijk, Zuid-Holland, male (R Hofland, N Aarts, G van der Bent et al).
This must be one of the dream birds to see whilst counting birds on migration. This fine male flying past was seen and described well enough by all observers to rule out other thrushes.

Eastern Black Redstart / Oosterse Zwarte Roodstaart
Phoenicurus ochruros phoenicuroides 0,1,2
8-12 November, Rolde, Aa en Hunze, Drenthe, first calendar-year male, photographed, sound-recorded, videoed (A-W Faber et al; Faber & Huiting 2012; Dutch Birding 34: 429, plate 605, 2012, 35: 63, plate 94, 2013); 9-12 November, Paesens, Dongeradeel, Friesland, first calendar-year male, photographed (B Duker, R Huiting et al; Faber & Huiting 2012; Dutch Birding 34: 429, plate 606, 2012, 35: 63, plate 95, 2013).
The second and third turned up within the period of just a few days. The first was at IJmuiden, Noord-Holland, on 21-23 October 2003 (Steijn 2005). Steijn (2005) investigated the crucial identification characters to safely exclude hybrids Common x Black Redstart P phoenicurus x ochruros. A bird photographed at Oosterend, Terschelling, Friesland, on 13 November 2011 and published as Eastern Black Redstart (Dutch Birding 34: 68, plate 90, 2012) was not accepted because the photographs showed not enough detail to establish the wing-tip spacing.

Stejneger's Stonechat / Stejnegers Roodborsttapuit
Saxicola stejnegeri 0,0,0
A report at Robbenjager, Texel, Noord-Holland, on 8-23 October is still under review. Remarkably, this same individual (established by a series of feather details visible on photographs) was relocated at Portland Bill, Dorset, England, on 24 October where it was trapped and stayed until 26 October. DNA analysis indicated this bird to be a Stejneger's Stonechat. It was accepted as such by the British rarities committee and now awaits formal admission to the British list (cf Kok 2012, Hudson & Rarities Committee 2013).

* Caspian Stonechat / Kaspische Roodborsttapuit
Saxicola maurus hemprichii 0,0,1
6-20 October, Kooisplek, Vlieland, Friesland, adult male, photographed, videoed (H Zevenhuizen, E Nieuwstraten et al; Bot et al 2012; Birding World 25: 421, 2012, Dutch Birding 34: 379, plate 521-524, 381, plate 525-526, 384, plate 527, 2012).
This isolated Caspian subspecies of Siberian Stonechat S maurus is a new taxon for the Dutch list. The bird belonged to the northern population of Caspian Stonechat, which is regarded as a separate subspecies S m hemprichii (separate from Armenian Stonechat S m variegatus (formerly S m armenicus)) by Svensson (2012) (cf Redactie Dutch Birding 2013). It was seen (and photographed) by a constant stream of admirers.

Siberian Stonechat / Aziatische Roodborsttapuit
Saxicola maurus maurus 9,32,1
13-15 October, Slufter, Texel, Noord-Holland, first calendar-year male, photographed (F van der Lans, F van der Lans, J Kleijweg et al).
A bird at Stengweg ('Tuintjes') near De Cocksdorp, Texel, Noord-Holland, on 25 October (according to the observer a bird different from the Stejneger's Stonechat S stejnegeri that stayed nearby until 23 October) has not (yet) been submitted. All birds accepted up to 2012 are provisionally listed as S m maurus but a revision will be necessary to exclude Stejneger's Stonechat S stejnegeri (now considered a full species, previously S m stejnegeri) or to accept them as Siberian/Stejneger's Stonechat.

Pied x Eastern Black-eared Wheatear
Oenanthe pleschanka x melanoleuca 0,0,0
A report of a first-summer male photographed on Texel, Noord-Holland, on 21 May is still under review.

Desert Wheatear / Woestijntapuit
Oenanthe deserti 1,30,0
2005 9-24 November, Kennemerstrand, IJmuiden, Velsen, first-winter male (B van 't Holt, R Rotscheid, R G M Altenburg et al; Dutch Birding 28: 60, plate 78, 356, plate 499, 2006).
This concerns a date extension for a bird earlier accepted for 11-24 November 2005 (van der Vliet et al 2006).

Collared Flycatcher / Withalsvliegenvanger
Ficedula albicollis 24,10,1
23-24 May, Vinkel, Maasdonk, Noord-Brabant, adult male, photographed (B van der Meulengraaf; Dutch Birding 34: 208, plate 284, 2012).

Alpine Accentor / Alpenheggenmus
Prunella collaris 0,8,2
28 April, Scheveningen, Den Haag, Zuid-Holland, possibly caught by cat, died next day at Vogelasiel de Wulp, photographed, skin retained at Naturalis Biodiversity Center at Leiden (R van der Vliet, S de la Parra et al); 21 May, Parkeerterrein Jan Ayeslag, Texel, Noord-Holland, second calendar-year, photographed, videoed (M Plomp et al; Dutch Birding 34: 204, plate 274, 2012).

Citrine Wagtail / Citroenkwikstaart
Motacilla citreola 0,34,2
30 April to 1 May, Azewijn, Oude IJsselstreek, Gelderland, maximum of two (on 30 April), females, photographed (R Schwartz, W Gerritsen, E Ernens et al; Dutch Birding 34: 208, plate 287, 2012).
The first record of two birds together.

Olive-backed Pipit / Siberische Boompieper
Anthus hodgsoni 0,26,19
6 October, Vliehors, Vlieland, Friesland, photographed (N Gilissen); 10 October, Vuurboetsduin, Vlieland, Friesland, photographed (S Radstaak, M Bunskoek, A Vink et al); 13 October, Westerduinen, Texel, Noord-Holland, photographed (R Wilschut, D Drukker); 15-20 October, De Koog, Texel, Noord-Holland, photographed, sound-recorded, videoed (D Kok, J van den Berg, H Brinks et al); 16-19 October, Colijnholte, Schiermonnikoog-Dorp, Schiermonnikoog, Friesland, photographed (W van der Ham, B van de Meulengraaf, E B Ebels et al); 17 October, Noordzijderpolder, Noordwijkerhout, Zuid-Holland, photographed, videoed, sound-recorded (M Wielstra, R van Rossum, A B van den Berg et al); 17-21 October, Hoornse Bos, Terschelling, Friesland, two, photographed, sound-recorded (R Jousma, G Jager, E Nieuwstraten et al); 17-25 October, Ruige Plak, Oost-Vlieland, Vlieland, Friesland, maximum of four (four on 18 October, three on 19-23 October, two on 17 and 24 October), photographed, sound-recorded (C Beeke, N van Duivendijk et al); 19 October, Vulkaan, Den Haag, Zuid-Holland, photographed (E Opperman); 19 October, Noordhollands Duinreservaat, Castricum, Noord-Holland, first calendar-year, ringed, photographed, sound-recorded (H Levering, J Visser, A J van Loon et al); 20 October, Noordhollands Duinreservaat, Castricum, Noord-Holland, ringed, photographed (P Admiraal et al); 20 October, Esdoornlaan, Oost-Vlieland, Vlieland, Friesland, photographed (R Hofland); 27 October, Vliehors, Vlieland, Friesland, photographed, sound-recorded (S Lagerveld, B Lagerveld, L Edelaar et al); 31 October to 4 November, Robbenoordbos, Hollands Kroon, Noord-Holland, two, photographed (L van der Vaart, O de Vries, A ten Hoeve et al).
2011 27 September, Schiermonnikoog, Schiermonnikoog, Friesland, photographed (W B Janssen).
The autumn of 2012 experienced by far the largest influx of this Siberian pipit ever in western Europe. In Britain, at least 52 birds were recorded, an all-time high in the last year for which the species was considered by the British rarities committee (Hudson & Rarities Committee 2013). At Robbenoordbos, up to four birds were reported in the first days of November but the committee so far received only conclusive evidence for two individuals. The number of records for 2012 is not yet complete. A few reports are still under consideration or have not (yet) been submitted. Consequently, the number of individuals may rise to more than 20. The previous year record was four in 2010.

Arctic Redpoll / Witstuitbarmsijs
Carduelis hornemanni 43,69,0
2010 24 November, Groene Glop, Schiermonnikoog, Friesland, adult male, ringed, photographed (H Bouwmeester, H Huiskamp).
1988 28 December to 16 January 1989, Pampushaven, Almere, Flevoland (R Nuiver, A Vink, M Olthoff et al).
The 1988/89 record concerns a date extension for a bird earlier accepted for 7-8 January 1989 (van den Berg & Bosman 2001). The totals exclude Hornemann's Redpoll C h hornemanni (one).

Two-barred Crossbill / Witbandkruisbek
Loxia leucoptera 36,228,2
25 April to 3 June, between West-Terschelling and West aan Zee, Terschelling, Friesland, male and adult female, photographed (H van Diek, J de Jong et al; Dutch Birding 34: 201, plate 267, 2012).
2004 22 October, Landgoed de Eese, Steenwijk, Overijssel, adult male, photographed (J van Arkel).
The male and female on Terschelling were present throughout the breeding season in suitable habitat but no definite proof of breeding was found, although a possible juvenile was reported on (only) 9 May. The plumage of the male was bright golden-yellow, not the regular pinkish-red. This feature (which may be diet related) is well known in Red Crossbill L curvirostra (Cramp & Perrins 1994).

Cretzschmar's Bunting / Bruinkeelortolaan
Emberiza caesia 1,2,0
2011 13-17 May, Rottumerplaat, Eemsmond, Groningen, male, photographed (B Spaans, H Roersma, N van Brederode et al; Ebels et al 2013; Dutch Birding 33: 209, plate 248, 280, plate 364, 2011, 34: 371, plate 518, 2012, 35: 180, plate 203, 2013).
This concerns a date extension for a bird previously accepted for 13-16 May 2011 (Ovaa et al 2012).

Rustic Bunting / Bosgors
Emberiza rustica 14,69,-
2008 3 October, Rottumeroog, Eemsmond, Groningen, female or first-winter, photographed (J van der Weele).
This species is no longer considered from 1 January 2009 but the CDNA still welcomes reports from before this date.

Systematic list of rejected reports

This list contains all records not accepted by the CDNA. Records marked with @ were rejected by all committee members in the first or second voting. Most records were rejected because the identification was not fully established (often due to lack of documentation) or when the bird showed signs of captivity, such as dubious rings, excessive wear and/or aberrant behaviour. Species, for which the CDNA unanimously decided that all records up to and including 2012 refer to birds of captive origin, are indicated with an asterisk (*). This included records of birds of which all ancestors are assumed to be of captive origin (introduced species of British category C).

Ross's Goose / Ross' Gans Anser rossii 25 October, Werkendam, Noord-Brabant, adult, white morph, photographed (@ identification accepted but legs not visible on photographs, so it was impossible to exclude presence of rings).

Booted Eagle / Dwergarend Aquila pennata 5 May, Holysloot, Waterland, Noord-Holland, two (description incomplete); 11 July, Middenduin, Overveen, Bloemendaal, Noord-Holland (@ description was accompanied by photographs of a probable stork, a probable Short-toed Snake Eagle Circaetus gallicus, a Bonelli's Eagle A fasciata and a pale morph Booted Eagle). Alpine Swift / Alpengierzwaluw Apus melba 23 October, Berkheide, Wassenaar, Zuid-Holland (@ description incomplete). Calandra Lark / Kalanderleeuwerik Melanocorypha calandra 8 May, Noordkaap, Eemsmond, Groningen (incomplete description of bird flying by); 22 May, Kapittelduinen, Hoek van Holland, Rotterdam, Zuid-Holland (CDNA was not totally convinced that a European Skylark Alauda arvensis also present and misidentified by many observers as Calandra Lark was fully excluded. This confusion made it unsafe to accept this record). Iberian Chiffchaff / Iberische Tjiftjaf Phylloscopus ibericus 13 April to 1 May, De Kwakel, Uithoorn, Noord-Holland, photographed, sound-recorded, videoed (song not typical for this species).

Eastern Yellow Wagtail / Oostelijke Gele Kwikstaart Motacilla tschutschensis, 21 October, Oost-Vlieland, Vlieland, Friesland, first calendar-year, photographed, sound-recorded (@ CDNA is, based on current knowledge, not able to exclude all other yellow wagtail taxa and possible hybrids).

2009
Arctic Warbler / Noordse Boszanger Phylloscopus borealis 26-27 September, Robbenjager, Texel, Noord-Holland, photographed, videoed (documentation shows wing-barred Phylloscopus, probably Greenish Warbler P trochiloides or Two-barred Warbler P plumbeitarsus, but photographs, video images and descriptions were considered not conclusive and described sound appeared to be at odds with both species; the observation has recently been resubmitted as Two-barred, accompanied by detailed analysis of all available documentation).

Golden Eagle / Steenarend Aquila chrysaetos 3 February, Westerveen, Noordenveld, Drenthe (description incomplete).

1800-2006
For the revision of Baillon's Crake / Kleinst Waterhoen Porzana pusilla records for the period 1800-2006, see Jansen (2013); in total, 155 individuals (out of 265) were not accepted, including several multiple reports and breeding reports. Not all rejected reports listed had been accepted in the past, because many previously unknown reports traced by the author were included in the revision. All decisions published in Jansen (2013) have been adopted by the CDNA and are not repeated here.
