The Greylag is the largest and bulkiest of the grey Anser geese. It has a rotund, bulky body, a thick and long neck, and a large head and bill. It has pink legs and feet, and an orange or pink bill. It is 74 to 91 cm (29 to 36 in) long with a wing length of 41.2 to 48 cm (16.2 to 19 in). It has a tail 6.2 to 6.9 cm (2.4 to 2.7 in), a bill of 6.4 to 6.9 centimetres (2.5 to 2.7 in) long, and a tarsus of 7.1 to 9.3 centimetres (2.8 to 3.7 in). It weighs 2.16 to 4.56 kg (4.8 to 10.1 lb), with a mean weight of around 3.3 kg (7.3 lb). The wingspan is 147 to 180 cm (58 to 71 in). Males are generally larger than females, with the sexual dimorphism more pronounced in the eastern subspecies rubirostris, which is larger than the nominate subspecies on average. The plumage of the Greylag Goose is greyish-brown, with a darker head and paler belly with variable black spots. Its plumage is patterned by the pale fringes of its feathers. It has a white line bordering its upper flanks. Its coverts are lightly coloured, contrasting with its darker flight feathers. Juveniles differ mostly in their lack of a black-speckled belly.
