The Goose Terms
Goose Groups
The geese (in the family Anatidae, tribe Anserini) are divided into two groups, the black geese (Branta) and the grey geese (Anser). The black geese are geese with areas of solid black plumage and the grey geese are geese without solid areas of black plumage (they look rather grey as a result hence the name). Our three geese here belong to:
The broad chin band of the Canadian Goose is conspicuous even from a distance. |
Common Name Latin Name Group
Greylag Goose Anser anser grey
Canadian Goose Branta canadensis black
Brent Goose Branta bernicla black
Goose Sexes and Juvenile Names
A male goose is called a gander and a female goose is just a goose, whereas a male and female swan are a cob and a pen and in ducks a drake and duck. A juvenile goose is a gosling but in the field guides chick or juvenile or immature are mainly used. The calls of geese are referred to by most as honking as geese do make trumpeting honks.
Goose Alternative Names
There are alternative names for many birds. The Greylag Goose is spelt in the United States as Graylag and the Canadian Goose is just the plain Canada Goose in the bird books. Some people call Brent Geese Brant Geese. Be careful with American bird field guides as birds which occur over here in Britain (or if you are American, the opposite) because birds that occur in both countries may be called different things e.g. the Little Tern is called by that name in Britain, but is called the Least Ten in America.
The Geese
The Canadian Goose
Appearance: The Canadian Goose is a large goose, sometimes described as swanlike, although smaller than a swan. The bill, head and long neck are black, with a broad white chin band, touching the eye and extending to the crown. The upperparts and wings are brown with pale feather edging and the legs are dark. The rump is white and the underparts are pale with no clear definition between the flank colouring and the belly.

Sorry if the labels on this diagram are a bit small. I should have written them bigger.

The Greylag Goose
The Greylag Goose is not as big as the Canadian Goose but bigger than the Brent Goose. It is grey all over but with pale feather edges and it grazes in fields but never on eelgrass like Brent Geese. They fly in a v shape when migrating. The legs of these geese are pink and the bill is orange and very big and heavy compared to the bills of other geese.

You can read the writing well on this diagram. Woo!
