White-rumped Sandpiper can be difficult to distinguish from
other similar tiny shorebirds; that are known collectively
as 'peeps'. One of the best identification features is the
long wings which extend beyond the tail when the bird is on
the ground. Other useful features include a pale base to the
lower mandible, a clear supercilium and obvious streaks
along the flanks. Only the Baird's Sandpiper shows a primary
projection and that bird can be distinguished by the lack of
a white rump.
