Two-barred Warbler at Kamperhoek in November 2013-January 2014

On 23 November 2013, a Two-barred warbler Phylloscopus plumbeitarus was trapped and ringed at Kamperhoek, Flevoland, the Netherlands. On 29 November, it was refound in the field and then observed by many birders on the next days. After 3 December, it was reported infrequently and the last sighting was on 3 January 2014. Identification was based on, eg, the double wing-bar, lack of a white tip to the tertials, silver-white underparts and flank (more greyish in Arctic Warbler P borealis), and emarginations on four primaries (not three, as in Arctic). The record has been accepted as the third for the Netherlands; earlier records were at Castricum, Noord-Holland, on 17 September 1990 (trapped) and on Terschelling, Friesland, on 2 October 1996 (first identified as Arctic but re-identified as Two-barred).
