*Decided to move this from the European Birds section where it appears to have "died".
Attached is a photograph of a pluvialis taken on 12th November 2007 at the Ria de Alvor, Algarve, Southern Portugal. It is not a good shot but I cannot get closer then about 100 metres to the bird. This bird arrived here (or at least I first noticed it here) in June 2002 and has not moved away since then! It does occasionally go onto the estuary at low tide to feed but is mainly confined to an area of marshland approximately 400 square meters in size. It seems to prefer to be in shallow water rather than on dry land. Its moult from winter to summer plumage is very subtle and mainly consists of developing an overall more yellow plumage together with a very distinct white supercillium (I will try to dig out an even poorer digiscoped shot of it in summer plumage). It has never developed any dark head or belly plumage, so I assume that it is a female.
The bird is a "loner" even though we now have a large flock (ca 400) of European Golden Plover in close vicinity, all of which are very vocal when in flight or even at roost. This bird appears to be a "mute".
I have a bit more information which I will disclose in due course, but for now just wanted to see what others who are familiar with all three pluvialis species think about this bird.
