ID tip

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 grey. The western sandpiper acquires winter plumage much earlier in the autumn than the semipalmated sandpiper. Measurements: Length: 14–17 cm (5.5–6.7 in) Wingspan: 35–37 cm (14–15 in) Weight: 22–35 g (0.78–1.23 oz)

About the Western Sandpiper

The western sandpiper is a small migratory shorebird. The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds. The specific mauri commemorates Italian botanist Ernesto Mauri (1791–1836).
