Australian magpie

The Australian magpie (Gymnorhina tibicen) is a medium-sized black and white passerine bird native to Australia and southern New Guinea. Although once considered to be three separate species, it is now considered to be one, with nine recognised subspecies. A member of the Artamidae, the Australian magpie is placed in its own genus Gymnorhina and is most closely related to the black butcherbird (Melloria quoyi). It is not, however, closely related to the European magpie, which is a corvid. The adult Australian magpie is a fairly robust bird ranging from 37 to 43 cm (14.5 to 17 in) in length, with distinctive black and white plumage, gold brown eyes and a solid wedge-shaped bluish-white and black bill. The male and female are similar in appearance, and can be distinguished by differences in back markings. The male has pure white feathers on the back of the head and the female has white blending to grey feathers on the back of the head. With its long legs, the Australian magpie walks rather than waddles or hops and spends much time on the ground. Described as one of Australia's most accomplished songbirds, the Australian magpie has an array of complex vocalisations. It is omnivorous, with the bulk of its varied diet made up of invertebrates. It is generally sedentary and territorial throughout its range. Common and widespread, it has adapted well to human habitation and is a familiar bird of parks, gardens and farmland in Australia and New Guinea. This species is commonly fed by households around the country, but in spring a small minority of breeding magpies (almost always males) become aggressive and swoop and attack those who approach their nests. Over 1000 Australian magpies were introduced into New Zealand from 1864 to 1874 but have subsequently been accused of displacing native birds and are now treated as a pest species. Introductions also occurred in the Solomon Islands and Fiji, where the birds are not considered an invasive species. The Australian magpie is the mascot of several Australian sporting teams, most notably the Collingwood Magpies, the Western Suburbs Magpies and Port Adelaide Magpies. The Australian magpie was first described by English ornithologist John Latham in 1801 as Coracias tibicen, the type collected in the Port Jackson region. Its specific epithet derived from the Latin tibicen 'flute-player' or 'piper' in reference to the bird's melodious call. An early recorded vernacular name is piping poller, written on a painting by Thomas Watling, one of a group known collectively as the Port Jackson Painter, sometime between 1788 and 1792. Tarra-won-nang, or djarrawunang, wibung, and marriyang were names used by the local Eora and Darug inhabitants of the Sydney Basin. Booroogong and garoogong were Wiradjuri words, and carrak was a Jardwadjali term from Victoria. Among the Kamilaroi, it is burrugaabu, galalu, or guluu. It was known as Warndurla among the Yindjibarndi people of the central and western Pilbara. Other names used include piping crow-shrike, piper, maggie, flute-bird and organ-bird. The term bell-magpie was proposed to help distinguish it from the European magpie but failed to gain wide acceptance. The bird was named for its similarity in colouration to the European magpie; it was a common practice for early settlers to name plants and animals after European counterparts. However, the European magpie is a member of the Corvidae, while its Australian counterpart is placed in the family Artamidae (although both are members of a broad corvid lineage). The Australian magpie's affinities with butcherbirds and currawongs were recognised early on and the three genera were placed in the family Cracticidae in 1914 by John Albert Leach after he had studied their musculature. American ornithologists Charles Sibley and Jon Ahlquist recognised the close relationship between woodswallows and the butcherbirds in 1985, and combined them into a Cracticini clade, in the Artamidae. The Australian magpie is placed in its own monotypic genus Gymnorhina which was introduced by the English zoologist George Robert Gray in 1840. The name of the genus is from the Ancient Greek gumnos for 'naked' or 'bare' and rhis, rhinos 'nostrils'. Some authorities such as Glen Storr in 1952 and Leslie Christidis and Walter Boles in their 2008 checklist, have placed the Australian magpie in the butcherbird genus Cracticus, arguing that its adaptation to ground-living is not enough to consider it a separate genus. A molecular genetic study published in a 2013 showed that the Australian magpie is a sister taxon to the black butcherbird (Melloria quoyi) and that the two species are in turn sister to a clade that includes the other butcherbirds in the genus Cracticus. The ancestor to the two species is thought to have split from the other butcherbirds between 8.3 and 4.2 million years ago, during the late Miocene to early Pliocene, while the two species themselves diverged sometime during the Pliocene (5.8–3.0 million years ago). The Australian magpie was subdivided into three species in the literature for much of the twentieth century—the black-backed magpie (G. tibicen), the white-backed magpie (G. hypoleuca), and the western magpie (G. dorsalis). They were later noted to hybridise readily where their territories crossed, with hybrid grey or striped-backed magpies being quite common. This resulted in them being reclassified as one species by Julian Ford in 1969, with most recent authors following suit. There are currently thought to be nine subspecies of the Australian magpie, although there are large zones of overlap with intermediate forms between the taxa. There is a tendency for birds to become larger with increasing latitude, the southern subspecies being larger than those further north, except the Tasmanian form which is small. The original form, known as the black-backed magpie and classified as Gymnorhina tibicen, has been split into four black-backed races:
