MP, 25May. Lesser Sand Plover (atrifrons)?

Too blur for good ID, but it looks like Greater Sand Plover to me.

Yes, I agree with Greater Sand Plover.
Because it is largely in breeding plumage, the best clue on this bird is the breast band. On this bird the breast band is typically very narrow and even width across the breast. Lesser Sand Plover (including [i]atrifrons[/i]) has a broader breast band, often spreading onto the belly/flanks. The long, heavy bill of this bird also looks typical for Greater Sand Plover.
Beware that Greater Sand Plover in Hong Kong can sometimes show an almost complete black forehead, which could cause confusion with [i]atrifrons[/i] (although it's not clear if this bird has white on the forehead or not). It is better to rely on several features rather than only the forehead pattern.

"atrifrons" Lesser Sand Plover

FWIW, here is an "atrifrons" Lesser Sandplover - with a broader breast band as described by ajohn above

Thanks John. This bird also shows the bill structure well - compare it against the long, heavy bill typical of Greater Sand Plover.

Thanks all for your advice. I was wondering what is the extend of wide breast-band and the image for the atrifrons told the difference. Thanks again!
