Red-necked Stint

The red-necked stint is among the smallest waders, 13–17 centimetres long with a wingspan of 28–37 centimetres and a weight of 21–51 grams. It is very similar to the little stint, with which it was once considered a single species. Its small size, fine dark bill, dark legs and quicker movements distinguish it from all waders except the other dark-legged stints, and a fine bill tip, unwebbed toes and longer primary projection separate it from the western and semipalmated sandpipers in all plumages.

A small, strongly migratory wader, it breeds along the Arctic coast of eastern Eurasia, in northeast Russia, and spends the non-breeding season on the coasts of Southeast Asia and Australasia, as far south as Tasmania and New Zealand. It is a rare vagrant to western Europe, with records from several countries, and is often seen in western Alaska and occasionally elsewhere in the Americas. (Wikipedia, general species account)
