Not quite sure where to post this since it is neither a beginner or advanced query.
Black-winged Stilt is a common resident breeding bird here and as well as seeing the 40+ local birds on the marsh every day, I see many hundreds of this species wherever I go along the Algarve coast (and in southern Spain).
Recently my wife pointed out an "odd" stilt (I tend not to scrutinize common birds too closely) and when I looked I became a bit excited since there have been reports of a Black-necked Stilt in Spain not long ago. My first views of the bird were of it facing away and rather hunched and it did indeed look as though the black extended from the nape right down to the mantle. Subsequent views show this not to be the case and there is a white "gap" between nape and mantle.
Having done a literature search I now know that Himantopus sp. are extremely variable in the amount of black on the head and neck of adult males, but I have never seen an example of the nominate European species with as much black as this bird.
So, the attached photos are just for your comments; has anyone seen a bird like this in S Europe? (By the way, the third photo shows him with his mate and they have now built their nest and she is "sitting" - it will be interesting to see what the off-spring look like).
