The magpie goose (Anseranas semipalmata) is the sole living representative species of the family Anseranatidae. This common waterbird is found in northern Australia and southern New Guinea. [2] As the species is prone to wandering, especially when not breeding, it is sometimes recorded outside its core range. [2] 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, [3] as subjects of recreational hunting, [4] and as a tourist attraction, their expansive and stable presence in northern Australia has been "ensured [by] protective management". [5]

Description

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

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. [6]

A cladistic study of the morphology of waterfowl found that the magpie goose was an early and distinctive offshoot, diverging after screamers and before all other ducks, geese, and swans. [7]

This family is quite old, a living fossil, having apparently diverged before the Cretaceous–Paleogene extinction event — the relative Vegavis iaai lived some 68-67 million years ago. The fossil record is limited, nonetheless. The enigmatic genus Anatalavis (Hornerstown Late Cretaceous or Early Paleocene of New Jersey, USA - London Clay Early Eocene of Walton-on-the-Naze, England) is sometimes considered to be the earliest known. Other Paleogene birds sometimes considered magpie-geese are the genera Geranopsis from the Hordwell Formation Late Eocene to the Early Oligocene of England and Anserpica from the Late Oligocene of Billy-Créchy (France). [8]

The earliest known member of the group in Australia is Eoanseranas represented by fossils found in the late Oligocene Carl Creek Limestone of Queensland. [9] Additional fossils from North America and Europe suggest that the family was spread across the globe during the late Paleogene period. [10] 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.[ original research? ]

Ecology and status

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. [11]

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 5-14 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. [12] In the December 2007 Flora and Fauna Guarantee Act list of threatened fauna, it is also listed. [13] [14] As of early 2008, an Action Statement for the recovery and future management of this species had not been prepared. [15]

With the advent of climate change, and more frequent seawater inundations of the current extensive freshwater floodplains, CSIRO scientists argue that magpie geese populations may be at risk. [16]

In Aboriginal languages

The Kunwinjku of western Arnhem Land know this bird as manimunak. [17] 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. [18] In Yolŋu Matha the bird is known as gurrumaṯtji, [19] or around Ramingining as gumang. [20]

In the Wadawurrung language, the magpie goose is known as Ngangok.

<span class="mw-page-title-main">Goose</span> Common name for a group of waterfowl

A goose is a bird of any of several waterfowl species in the family Anatidae. This group comprises the genera Anser and Branta. Some members of the Tadorninae subfamily are commonly called geese, but are not considered "True Geese" taxonomically. More distantly related members of the family Anatidae are swans, most of which are larger than true geese, and ducks, which are smaller.

<span class="mw-page-title-main">Anatidae</span> Biological family of water birds

The Anatidae are the biological family of water birds that includes ducks, geese, and swans. The family has a cosmopolitan distribution, occurring on all the world's continents except Antarctica. These birds are adapted for swimming, floating on the water surface, and in some cases diving in at least shallow water. The family contains around 174 species in 43 genera.

<span class="mw-page-title-main">Anseriformes</span> Order of water birds

Anseriformes is an order of birds also known as waterfowl that comprises about 180 living species of birds in three families: Anhimidae, Anseranatidae, and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans. Most modern species in the order are highly adapted for an aquatic existence at the water surface. With the exception of screamers, males have penises, a trait that has been lost in the Neoaves. Due to their aquatic nature, most species are web-footed.

<span class="mw-page-title-main">Anserinae</span> Subfamily of birds

The Anserinae are a subfamily in the waterfowl family Anatidae. It includes the swans and the true geese. Under alternative systematical concepts, it is split into two subfamilies, the Anserinae contain the geese and the ducks, while the Cygninae contain the swans.

<span class="mw-page-title-main">Oxyurini</span> Tribe of birds

The Oxyurini are a tribe of the duck subfamily of birds, the Anatinae. It has been subject of considerable debate about its validity and circumscription. Some taxonomic authorities place the group in its own subfamily, the Oxyurinae. Most of its members have long, stiff tail feathers which are erected when the bird is at rest, and relatively large, swollen bills. Though their relationships are still enigmatic, they appear to be closer to swans and true geese than to the typical ducks. The highest diversity is found in the warmer parts of the Americas, but at least one species occurs in a major part of the world.

<span class="mw-page-title-main">Anseranatidae</span> Family of birds

Anseranatidae, the magpie-geese, is a biological family of waterbirds. The only living species, the magpie goose, is a resident breeder in northern Australia and in southern New Guinea.

<i>Branta</i> Genus of birds

The black geese of the genus Branta are waterfowl belonging to the true geese and swans subfamily Anserinae. They occur in the northern coastal regions of the Palearctic and all over North America, migrating to more southerly coasts in winter, and as resident birds in the Hawaiian Islands. Alone in the Southern Hemisphere, a self-sustaining feral population derived from introduced Canada geese is also found in New Zealand.

Anas is a genus of dabbling ducks. It includes the pintails, most teals, and the mallard and its close relatives. It formerly included additional species but following the publication of a molecular phylogenetic study in 2009 the genus was split into four separate genera. The genus now contains 31 living species. The name Anas is the Latin for "duck".

<span class="mw-page-title-main">Pygmy goose</span> Genus of birds

The pygmy geese are a group of very small "perching ducks" in the genus Nettapus which breed in the Old World tropics. They are the smallest of all wildfowl. As the "perching ducks" are a paraphyletic group, they need to be placed elsewhere. The initially assumed relationship with the dabbling duck subfamily Anatinae has been questioned, and it appears they form a lineage in an ancient Gondwanan radiation of waterfowl, within which they are of unclear affinities. An undescribed fossil species from the late Hemphillian of Jalisco, central Mexico, has also been identified from the distal end of a tarsometatarsus. It is only record of the genus in the New World.

<i>Anser</i> (bird) Genus of birds

Anser is a waterfowl genus that includes the grey geese and the white geese. It belongs to the true goose and swan subfamily of Anserinae under the family of Anatidae. The genus has a Holarctic distribution, with at least one species breeding in any open, wet habitats in the subarctic and cool temperate regions of the Northern Hemisphere in summer. Some also breed farther south, reaching into warm temperate regions. They mostly migrate south in winter, typically to regions in the temperate zone between the January 0 °C (32 °F) and 5 °C (41 °F) isotherms.

<i>Dromornis</i> Extinct genus of birds

Dromornis is a genus of large to enormous prehistoric birds native to Australia during the Oligocene to Pliocene epochs. The species were flightless, possessing greatly reduced wing structures but with large legs, similar to the modern ostrich or emu. They were likely to have been predominantly, if not exclusively, herbivorous browsers. The male of the largest species, Dromornis stirtoni, is a contender for the tallest and heaviest bird, and possibly exhibited aggressive territorial behaviour. They belong to the family Dromornithidae, extinct flightless birds known as mihirungs.

Serendip Sanctuary is a 250 ha protected area in Victoria, Australia, near the You Yangs and the town of Lara, some 22 km (14 mi) north of Geelong and 60 km (37 mi) south-west of Melbourne. Originally used for farming and other purposes, it was purchased in 1959 by the State Government of Victoria for wildlife research and the captive management and breeding of species threatened in Victoria, such as the brolga, magpie goose, Australian bustard, and bush stone-curlew. The sanctuary contains many different types of wetland and is home to many plant species as well, such as river red gums, tall spikerush, and tussock grass. Serendip now focuses more on environmental education about the flora and fauna of the wetlands and open grassy woodlands of the Volcanic Western Plains of Victoria. It was opened to the public in 1991 and is now managed by Parks Victoria.

Anatalavis is genus of prehistoric birds related to ducks and geese, perhaps to the magpie-goose in particular. Alternatively, it might have been a more basal lineage of Anserimorphae distinct from the living waterfowl, similar or even related to the roughly contemporary Conflicto antarcticus from the Danian of Antarctica.

Eoanseranas handae, also sometimes referred to as Hand's dawn magpie goose, is an extinct genus and species of bird. Allied to the family Anseranatidae, which are represented by modern magpie geese, it existed during the Late Oligocene or Early Miocene of northern Australia. It was described from fossil material found at a Carl Creek Limestone site at Riversleigh, in the Boodjamulla National Park of northwestern Queensland. It was slightly smaller than its perceived descendant, the extant magpie goose Anseranas semipalmata.
