Magpie goose

The magpie goose is the sole living representative species of the family Anseranatidae. This waterbird is found in northern Australia and southern New Guinea. The species is not truly migratory but it sometimes travels large distances to find food and water, especially when not breeding, and is sometimes recorded outside its core range. 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. Due to their importance to Aboriginal people as a seasonal food source, as subjects of recreational hunting, and as a tourist attraction, their expansive and stable presence in northern Australia has been "ensured [by] protective management".

Description
The magpie goose has black-and-white plumage in both sexes, with a long neck and legs and a long hooked bill. It is typically 75–90 cm (30–35 in) in length with an average weight of around 3 kg (6.5 lb). 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 molt is gradual, so no flightless periods result. Their voice is a loud honking. ==Systematics and evolution==
Systematics and evolution
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 the genus Anseranas and family Anseranatidae, which are monotypic now. Additional fossils from North America and Europe suggest that the family was spread across the globe during the late Paleogene period. The Australian distribution of the living species ties in well with the presumed Gondwanan origin of Anseriformes, but Northern Hemisphere fossils are puzzling. Perhaps the magpie geese were one of the dominant groups of Paleogene waterfowl, only to become largely extinct later. ==Ecology and status==
Ecology and status
, Singapore) The magpie goose is found in a variety of open wetland areas such as floodplains and swamps, where they wade and swim. They eat mostly vegetation such as dry grass blades, grass seeds, spike rush bulbs and wild rice. Magpie geese are fairly sedentary apart from some movement during the dry season. 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. Magpie geese nest on the ground or in trees where they can be five meters or higher above the ground. Their typical clutch is between five and 14 eggs. Some males mate with two females, all of which raise the young, unlike some other polygamous birds. This may be beneficial when predation of young is high as chicks raised by trios are more likely to survive. This species is plentiful across its range, although this is significantly reduced in comparison to the range at time of European settlement. The range once extended as far south as the Coorong and the wetlands of the southeast of South Australia and Western Victoria. For Australia as a whole, it is not threatened and has a controlled hunting season when numbers are large. However, most of the southern populations were extirpated in the mid-20th century by overhunting and habitat destruction. The species has been subject to reintroduction projects such as Bool Lagoon between Penola and Naracoorte. Populations in more northern areas have again reached a level where it can be regularly utilized by hunters, although not in the example provided. The magpie goose was listed as near threatened on the 2007 advisory list of threatened vertebrate fauna in Victoria. ==In Aboriginal languages==
In Aboriginal languages
The Kunwinjku of western Arnhem Land know this bird as manimunak. It became an important food item with the formation of wetlands about 1500 ya, and is depicted in rock art from this period. Mimi figures are often shown holding goose-feather fans. In Yolŋu Matha the bird is known as gurrumaṯtji, or around Ramingining as gumang. In the Wadawurrung language, the magpie goose is known as . ==Gallery==
