Geese are waterfowl belonging to the tribe Anserini of the family Anatidae. This tribe comprises the genera Anser (the grey geese), Branta (the black geese) and Chen (the white geese). Some other birds, mostly related to the shelducks, have "goose" as part of their names. More distantly related members of the family Anatidae are swans, most of which are larger than true geese, and ducks, which are smaller.


Geese first appeared in "Dinosaurs". An adult Canada goose and gosling were shown eating water plants in the water as Martin explained that ducks and geese have amazing bills with sharp edges that they use to grind water plants.

Canada geese also appeared in "The Four F's".
