Habitat Arctic Tern Bird

Arctic Tern bird is a summer visitor to higher latitudes than any other of our terns, it typically nests colonially and in the north of its range these colonies can be very large. Almost always found nesting close to the coast, on inshore islets and islands, shingle beaches, rocky shores, pastures, sedge moor and coastal meadows. In northern Scandinavia, however, Arctic Tern bird also nests far inland along rivers on islands and banks. Outside the breeding season it can be found migrating along the coasts of our region, occasionally visiting inland water bodies when weather conditions funnel migrants overland. It ha; possibly the longest migration of any bird, wintering in Antarctica.
