Greylag goose

Greylag Goose

The greylag or barnyard goose (Anser anser) is a domestic species native to Europe and parts of Asia. This species has been domesticated for thousands of years. The standard or wild type is gray, but there are many variations in size and color. This species is large and bulky, bred to provide a lot of meat. Males typically weigh 3.5-3.8 kg (7.7-8.4 lb); females range from 2.7-3.1 kg (6.0-6.8 lb).

Greylag geese consume a variety of foodstuffs, however plant material like grass, roots, leaves, stems, seed-heads, and sprouts, make up the bulk of the diet.
