Ruddy Turnstone 翻石鷸

Black-headed Gull 紅嘴鷗

Now you know, although my head is brown, human beings called me black-headed because I don't have pale iris and I don't have white patches near wing tips of my primaries.

Don't land on my head, you brown headed black-headed!

The gull is a Black-headed. The name is a bit inappropriate, because this species has a brown head in breeding plumage!

I think it's a great photo of Grey-tailed Tattler.

Thank you very much, ajohn, for your comments. 'Brown-headed Gull' has been rectified to 'Black-headed Gull' as advised.

And one more photo - a plover with a very white face and relatively long legs (at centre of photo). Could this be a white-faced plover?

The plover in the last photo is a non-breeding Greater Sand Plover. They can be fairly pale-faced at times.

Thank you for your comment, ajohn. But I thought non-breeding Greater Sand Plover typically has a brown line between bill base and the eye, which is lacking on this bird?

Author: ajohn Time: 12/05/2015 23:33

It's true that the do have a dark line on the lores (between the eye and bill). But this can fade slightly over the winter, and may not be as obvious at certain angles (especially it seems when seen from the front as this bird). Notice that the bird slightly behind and to the left also seems to have a rather white face (although perhaps not as much).

Besides the white lores, there are a number of features that fit with this being a Greater Sand Plover and not White-faced e.g. large size, heavy bill, leg colour (dark olive, not pinkish), size of dark patches on the breast sides.

Thank you for your further elaborations, ajohn. I am still not convinced that this is non breeding Greater Sand Plover, as there is literature saying that Greater (and Lesser) Sand Plover does not have the white band extending to the back neck, which is seen on this bird.
As for the leg colour of White-Faced Plover, the pinkish colour could only be seen under strong direct sunlight, which is absent in the photo. In fact, many photos of White-Faced Plover in Oriental Bird Club Image Database do not show pinkish legs.
