Everything about Magpie Goose totally explained
The
Magpie-goose,
Anseranas semipalmata, is a waterbird found in
Australia and
New Guinea. It is a unique member of the
bird order
Anseriformes, and arranged in a separate
family and
genus.
The Magpie-goose is a resident breeder in northern Australia, where it isn't threatened and has a controlled hunting season when numbers are large, and in southern New Guinea. It is found in a variety of open wet areas such as floodplains and swamps. It is fairly sedentary apart from some movement during the dry season.
Its nest is on the ground, and a typical clutch is 5-14 eggs. Some males mate with two females.
Magpie-geese are unmistakable birds with their black and white plumage and yellowish legs. The feet are only partially webbed, although the Magpie-goose will feed on vegetable matter in the water as well as on land. Males are larger than females. Unlike true geese, the
moult is gradual, and there's no flightless period.
They are colonial breeders and are gregarious outside of the breeding season when they can form large and noisy flocks of up to a few thousand individuals. The voice is a loud honking.
This species is placed in the order
Anseriformes, having the characteristic bill structure, but is considered to be distinct from the other species in this
taxon. The related and extant families,
Anhimidae (
screamers) and
Anatidae (
ducks,
geese and
swans), contain all the other taxa. The Magpie-goose is contained in a
monotypic arrangement: the genus
Anseranas and family
Anseranatidae.
This family is quite old, having apparently diverged before the
Cretaceous–Tertiary extinction event. The
fossil record is limited, nonetheless, with an undescribed species from the Late
Oligocene of
Billy-
Créchy (
France) being known (Hugueney
et al, 2003). The enigmatic genus
Anatalavis (Hornerstown Late Cretaceous/Early Paleocene of New Jersey, USA - London Clay Early Eocene of Walton-on-the-Naze, England) is sometimes considered to be the earliest known anseranatid.
