The common greenshank (Tringa nebularia) is a wader in the large family Scolopacidae, the typical waders. This is a subarctic bird, breeding from northern Scotland eastwards across northern Europe and east across the Palearctic. It is a migratory species, wintering in Africa, the Indian subcontinent, and Australasia, usually on fresh water. 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 and amphibians.
The common greenshank is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.
