Claire Goose

A genus of prehistorically extinct seaducks, Chendytes, is sometimes called "diving-geese" due to their large size.
The unusual Magpie Goose is in a family of its own, the Anseranatidae.
The Northern Gannet, a seabird, is also known as the "Solan Goose" although it is a bird unrelated to the true geese, or any other Anseriformes for that matter.
