The male and female are similar in appearance, but can be distinguished by differences in back markings. The male has pure white feathers on the back of the head where the female has white blending to grey feathers. With its long legs, the Australian magpie walks rather than waddles or hops and spends much time on the ground.
Female in Melbourne. The female has a white throat and the male has a black throat. The magpie-lark is a small to medium size bird, reaching 25 to 30 cm (9.8 to 11.8 in) long when fully grown, or about the same size as a European common blackbird, and boldly pied in black and white; the weight range is 63.9 to 118 g (2.25 to 4.16 oz) for males, and 70 to 94.5 g (2.47 to 3.33 oz) for females.

[29] [30] Small for the size of the bird, they are typically pale blue-green, with close specks and spots of olive brown, but show much variation in ground and marking. [31] The eggs are incubated for 21–22 days by the female, who is fed on the nest by the male. [32] The chicks are altricial, hatching nearly naked with closed eyes.
The Australian magpie, Cracticus tibicen, is conspicuously "pied", with black and white plumage reminiscent of a Eurasian magpie. It is a member of the family Artamidae and not a corvid. The magpie-robins , members of the genus Copsychus , have a similar "pied" appearance, but they are Old World flycatchers , unrelated to the corvids.
However, such sex differences are primarily limited to the anthropoid primates; most of the strepsirrhine primates (lemurs and lorises) and tarsiers are monomorphic. [2] Sexual dimorphism can manifest itself in many different forms. In male and female primates there are obvious physical difference such as body size or canine size.
The magpie starling is about 16–19 cm (6.5–7.5 in) in length. The white patches at base of primaries are obvious in flight. The male is a shiny blue-black on upperparts, head and upper breast, with mostly white below and bloodred eyes. The female is a dull blackish above with dark grey crown, and a dark grey throat is separated from white ...
Incubation, by the female only, starts when the clutch is complete, and lasts 16–21 days. The nestling period is three to four weeks. Black-billed magpies in the wild have a lifespan of six to seven years. Black-billed magpies have a long history with humans, being featured in stories told by Indigenous tribes of the Great Plains.

The male and female are similar in appearance. Known for its melodious calls, the species' name currawong is believed to be of indigenous origin. Within its range, the pied currawong is generally sedentary , although populations at higher altitudes relocate to lower areas during the cooler months.
