Magpie geese

The magpie goose (Anseranas semipalmata) is the sole living representative waterbird species of the Anseranatidae family.

It is a resident breeder in northern Australia and a vagrant to southern New Guinea.

The species was once also widespread in southern Australia, but disappeared from there largely due to the drainage of the wetlands where the birds once bred.

Magpie geese are unmistakable birds with their black and white plumage and yellowish legs.

The feet are only partially webbed, and the magpie goose feeds on vegetable matter in the water, as well as on land.

Males are larger than females. Unlike true geese, their moult is gradual, so no flightless period results.

Their voice is a loud honking.
