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.
Male (left) and female (right) magpies of Tasmania. The Australian magpie (Gymnorhina tibicen) is a medium-sized black and white passerine bird native to Australia and southern New Guinea. Three subspecies, including both black-backed and white-backed magpies, were introduced to New Zealand from the 1860s to control pests in pastures. They are ...
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.

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.
The yellow-billed magpie lineage likely split off soon after due to the Sierra Nevada uplift and the beginning of an ice age. [9] A comparatively low genetic difference, however, suggests that some gene flow between the black-billed and yellow-billed magpies still occurred during interglacial periods until the Pleistocene.

The Eurasian magpie or common magpie (Pica pica) is a resident breeding bird throughout the northern part of the Eurasian continent. It is one of several birds in the crow family (corvids) designated magpies , and belongs to the Holarctic radiation of " monochrome " magpies.
On his first day back in office on Monday, President Trump issued an executive order declaring that the U.S. government would only recognize a person's sex assigned at birth, limit the definition ...
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.
