A large waterfowl in the Anatidae family.
A gander is a male goose. Young birds are called goslings. A group of geese on the ground is a gaggle; when in flight, they are called a skein, team, or wedge; when flying close together, they are called a plump.
Geese are larger than ducks and smaller than most swans.
