The Australian Magpie (Gymnorhina tibicen) is a medium-sized black and white passerine bird native to Australia and southern New Guinea. A member of the Cracticidae, it is closely related to the butcherbirds. At one stage, the Australian Magpie was considered to be three separate species, although zones of hybridisation between forms reinforced the idea of a single species with several subspecies, nine of which are now recognised. The adult Australian Magpie is a fairly robust bird ranging from 37 to 43 cm (14.5–17 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.
