| Interesting find indeed (at the same location as the thayeri it seems). It's noticable that in this image the tiny dark mark on p10 is totaly invisble. |

| P9 I mean...:-) |
|
| At this site two adults have been seen together, so photographs may concern different individuals (possibly different ssp and with different wing markings). |

| Good be Arnoud, but not in this case. In the picture after this one (taken in the same second) the dark mark is visible. It looks like when you see the bird with an angle from behind with its wings (stretched) up it is not visible. With the wings down it is. |
