The Graylag Goose (Greylag Goose) is considered the ancestor of most breeds of domestic goose. They are mostly dark gray all over, with a pinkish-orange bill which sometimes has a white tip at the end, and dull pink legs.

Graylag Geese in North America are often domesticated geese and may be too large to fly. Wild ones are rare to find here as they are originally from Europe.

Habitat And Diet

You may find Graylag Geese in marshes, lakes, and reservoirs during their breeding season. They prefer habitats with thick ground cover like reeds, rushes, and bushes. In winter, they are seen on saltwater marshes, estuaries, bogs, and even on agricultural land. 

Graylag Geese feed both on land and water. On land, they graze in pastures feeding on the grass with sheep or cows. They also feed on cereals, like oats, wheat, and barley, that they find in agricultural fields and farmlands.

Near or on water, Graylag Geese feed on aquatic plants and insects, such as small fish, amphibians, crustaceans, mollusks, and insects.
