Hi
I hope I'm not too boaring with my sandpipers....
I send more pictures on

We are only 20 of august, that's not so late...I don't think that all the
Western are in complete wintering plumage at this time, do they ??
This bird perhaps spend the northern summer here.... as some yellowlegs and
others shorebirds (I don't think that the 250 Baird's Sandpiper are
"arriving" bird as I didn't see any inland even in Peru where I've been 3
weeks ago). I think that these birds spend the northern summer here.

Yes, this bird have clearly markings on the hindmost portion of the flanks,
but also on the flanks (see the new pic Sandpip2-f).
I'm very surprise to learn that the Semipalmated sandpiper could also have
these kind of markings ! I didn't know it, and would like to see some
pictures of these kind of birds... do you have some ?

Fabrice
