- Calidris pusilla
Dark legs with partially webbed toes (best seen from rear), short, dark, straight bill, thinner at the tip but not as thin as Western Sandpiper. Most birds have shorter bills than Western Sandpiper but there is much overlap.
Breeding: pale basic color more ochre-brown than on Western Sandpiper with fewer and smaller dark spots on underside and mantle, scapulars with black centers but not showing a strong reddish-brown contrast, and brown or crown and ear-coverts less reddish and contrasting than on Western Sandpiper.
Winter: mostly pale grey upperside, white underside with darker ear-coverts and upper breast.
Juvenile: more uniform on back than western (lacking rufous V) but with a strong scaled effect, pale underside, darker ear-coverts and upper breast than Western Sandpiper. Dark stripes on crown can produce an effect as a dark cap.
