[65] Natural predators of magpies include various species of monitor lizard and the barking owl. The pied butcherbird has a similar build and plumage, but has white underparts unlike the former species' black underparts. Like corvids and raptors elsewhere in the world, Australian birds may use stones for a variety of purposes. Defending a common territory from other groups of magpies is their primary intention. In the extreme south-west, south-east, central Australia, and in Tasmania, the rump part and the back are completely white. The Australian magpie produces a clutch of two to five light blue or greenish eggs, which are oval in shape and about 30 by 40 mm (1.2 by 1.6 in) The chicks hatch synchronously around 20 days after incubation begins; like all passerines, the chicks are altricial—they are born pink, naked, and blind with large feet, a short broad beak and a bright red throat.Their eyes are fully open at around 10 days. [120] Such teams tend to wear uniforms with black and white stripes. With all other controls in place, this could only mean that magpies had recognized themselves in the mirrors.

[57] In general, evidence suggests the range and population of the Australian magpie has increased with land-clearing, although local declines in Queensland due to a 1902 drought, and in Tasmania in the 1930s have been noted; the cause for the latter is unclear but rabbit baiting, pine tree removal, and spread of the masked lapwing (Vanellus miles) have been implicated. More rarely, a bird may dive-bomb and strike the intruder's (usually a cyclist's) head with its chest. These non-breeding birds often form flocks with a home range of up to 20 hectares (about 50 acres) and may pair up within the flock. Black-backed subspecies have a black saddle and white nape. 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. They make a small hole in the ground with their beak, place the food in it and cover it with grass, a stone or a leaf. Across most of Australia, the remainder of the body is black.
