The Greenshank (Tringa nebularia) is a species of wading bird of the family Scolopacidae. It is a sub-Arctic bird, breeding from northern Scotland east across northern Europe and Asia. It is migratory and winters in Africa, south Asia, and Australia. It is usually a bird of fresh water in the winter. It is closely related to the Greater Yellowlegs.
Apart from the Willet, the Greenshank is the largest of the shanks. It has a coarse, dark, and fairly crisp breast pattern. The plumage in the breeding season is mostly brown, and more gray-brown in the winter. It has long greenish legs and a long bill with a gray base. It shows a white wedge on the back in flight. The alarm call is a loud trisyllabic whistle.
It breeds on dry ground near marshy areas, laying about four eggs in a ground scrape. Like most waders, they feed on small invertebrates, but will also take small fish. The Greenshank is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
