Sharp-tailed Sandpiper

The Sharp-tailed Sandpiper is a small-to-medium wader with a rather pot-bellied body, flat back, straight dark bill, and olive to yellow legs. Chestnut-brown upperparts have dark-centred feathers, while the crown is chestnut and a strong pale eyebrow crosses the face. Unlike the similar Pectoral Sandpiper, it lacks a sharply bounded breast band and instead shows chevron-like marks along the flanks. Breeding plumage is richer, and juveniles are especially bright and crisply patterned. (Wikipedia, Sharp-tailed Sandpiper account)

This strongly migratory sandpiper breeds in eastern Siberian tundra and winters chiefly in Australasia. During passage it uses muddy margins of shallow fresh or brackish wetlands, flooded sedges, saltmarshes, lagoons, and coastal mudflats. Birds pick prey from the surface or probe soft substrates, eating aquatic insects, molluscs, crustaceans, worms, other invertebrates, and occasional seeds. A ground nest is a leaf-and-grass-lined hollow, usually holding four eggs; the female incubates and raises the chicks. (Wikipedia, Sharp-tailed Sandpiper account)
