Description
The length ranges from 68 to 90 centimetres (27–35 in), wingspan from 140 to 174 centimetres (55–69 in) and weight from 1.7–4 kilograms (3.7–8.8 lb). In the nominate subspecies, males average 3.2 kg (7.1 lb) and females average 2.84 kg (6.3 lb). The bill is black at the base and tip, with an orange band across the middle; the legs and feet are also bright orange.
The upper wing-coverts are dark brown, as in the White-fronted Goose (Anser albifrons) and the Lesser White-fronted Goose (A. erythropus), but differing from these in having narrow white fringes to the feathers.
The voice is a loud honking, higher pitched in the smaller subspecies.
The closely related Pink-footed Goose (A. brachyrhynchus) has the bill short, bright pink in the middle, and the feet also pink, the upper wing-coverts being nearly of the same bluish-grey as in the Greylag Goose. In size and bill structure, it is very similar to Anser fabalis rossicus, and in the past was often treated as a sixth subspecies of Bean Goose.

“The next Augustan age will dawn on the other side of the Atlantic. There will, perhaps, be a Thucydides at Boston, a Xenophon at New York, and, in time, a Virgil at Mexico, and a Newton at Peru. At last, some curious traveller from Lima will visit England and give a description of the ruins of St. Paul’s, like the editions of Balbec and Palmyra.”
