The Gray-tailed Tattler (Tringa brevipes (formerly Heteroscelus brevipes)), is a species of shorebird found on stony riverbeds in northeast Siberia. Though it nests on the ground, it is often found perching in trees. It is a strongly migratory bird and winters on muddy and sandy coastal areas from southeast Asia to Australia. They are rare visitors to western North America and western Europe.
The Gray-tailed Tattler has unpatterned, grayish wings and back, and a scaly breast pattern that extends more or less onto the belly in breeding plumage. The eye-stripe is weak. This bird is similar in shape and size to the Common Redshank. The upperparts, underwings, face and neck are gray, and the belly is white. The legs are short and yellowish. The bill is yellow with a pale base and dark tip. The call is a disyllabic whistle.
This bird is not usually gregarious and is seldom seen in large flocks, except when roosting. It forages on the ground or in water, picking up food by sight. The diet consists of insects, crustaceans and other invertebrates.
The Gray-tailed Tattler is listed as threatened on the Victorian Flora and Fauna Guarantee Act (1988). On the 2007 advisory list of threatened vertebrate fauna in Victoria, it is listed as critically endangered. It is not listed as threatened on the Australian Environment Protection and Biodiversity Conservation Act 1999.
