The Greylag is a large goose, 74-84 cm (29-33 in) long with a 149-168 cm (59-66 in) wingspan and a body weight of 2.3-5.5 kg (5-12 lbs). It has a large head and almost triangular bill. The legs are pink, and the bird is easily identified in flight by the pale leading edge to the wing. It has a loud cackling call, kiYAAA-ga-ga, like the domestic goose.This species is found throughout the Old World, apparently breeding where suitable localities are to be found in many European countries, although it no longer breeds in southwestern Europe. Eastwards it extends across Asia to China.The geese are migratory, moving south or west in winter, but Scottish breeders, some other populations in northwestern Europe, and feral flocks are largely resident. This species is one of the last to migrate. One theory on the etymology of the name (American Heritage Dictionary) is that "-lag" derives from this "lagging behind", although the Oxford English Dictionary analyses "-lag" as a dialectical word for "goose", of unknown orig
