The bar-tailed godwit (''Limosa lapponica'') is a large wader in the family Scolopacidae, which breeds on Arctic coasts and tundra mainly in the Old World, and winters on coasts in temperate and tropical regions of the Old World and of Australia and New Zealand.〔del Hoyo, J., Elliott, A., & Sargatal, J., eds. (1996). ''Handbook of the Birds of the World'' Vol. 3. Lynx Edicions, Barcelona ISBN 84-87334-15-6.〕 Its migration is the longest known non-stop flight of any bird and also the longest journey without pausing to feed by any animal.〔 == Description == The bar-tailed godwit is a relatively short-legged species of godwit. The bill-to-tail length is , with a wingspan of . Males average smaller than females but with much overlap; males weigh , while females weigh ; there is also some regional variation in size (see subspecies, below). The adult has blue-grey legs and a slightly upturned bi-colored bill, pink at the base and black towards the tip. The neck, breast and belly are unbroken brick red in breeding plumage, off white in winter. The back is mottled grey.〔 It is distinguished from the black-tailed godwit (''Limosa limosa'') by its barred, rather than wholly black, tail and a lack of white wing bars. The most similar species is the Asiatic dowitcher. There are three subspecies, listed from west to east:〔〔 * ''Limosa lapponica lapponica'' (Linnaeus, 1758). Breeds from northern Scandinavia east to the Taymyr Peninsula; winters western coasts of Europe and Africa from the British Isles and the Netherlands south to South Africa, and also around the Persian Gulf. Smallest subspecies, males up to 360 g, females to 450 g. * ''Limosa lapponica menzbieri'' (Portenko, 1936). Breeds northeastern Asia from the Taymyr Peninsula east to the Kolyma River delta; winters southeastern Asia and Australia. Intermediate between the other two subspecies. * ''Limosa lapponica baueri'' (Naumann, 1836). Breeds far northeastern Asia east of the Kolyma River, and western Alaska; winters in Australia and New Zealand.
