Western Sandpiper
The Western Sandpiper, Calidris mauri, is a very small shorebird.
Adults have dark legs and a short thin dark bill, thinner at the tip. The body is brown on top and white underneath. They are reddish-brown on the crown. This bird can be difficult to distinguish from other similar tiny shorebirds, especially the Semipalmated Sandpiper. This is particularly the case in winter plumage, when both species are plain gray. Western Sandpiper acquires winter plumage much earlier in the autumn than Semipalmated Sandpiper.
Their breeding habitat is on tundra in eastern Siberia and Alaska. They nest on the ground usually under some vegetation.
They migrate to both coasts of North America and South America. It is a very rare vagrant to western Europe.
These birds forage on mudflats by probing or picking up food by sight. They mainly eat insects, small crustaceans and mollusks.
This is the most abundant shorebird in western North America with a population in the millions.
