A passerine is any bird of the order Passeriformes which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement of their toes, which facilitates perching.
Magpies are birds of the family Corvidae. Like other members of their family, they are widely considered to be intelligent creatures. The Eurasian magpie, for instance, is thought to rank among the world's most intelligent creatures and is one of the few nonmammalian species able to recognize itself in a mirror test. They are particularly well known for their songs and were once popular as cagebirds. In addition to other members of the genus Pica, corvids considered as magpies are in the genera Cissa, Urocissa, and Cyanopica.
Corvidae is a cosmopolitan family of oscine passerine birds that contains the crows, ravens, rooks, magpies, jackdaws, jays, treepies, choughs, and nutcrackers. In colloquial English, they are known as the crow family or corvids. Currently, 135 species are included in this family. The genus Corvus containing 47 species makes up over a third of the entire family. Corvids (ravens) are the largest passerines.
The yellow-billed magpie(Pica nuttalli), also known as the California magpie, is a large corvid that inhabits California's Central Valley and the adjacent chaparral foothills and mountains. Apart from its having a yellow bill and a yellow streak around the eye, it is virtually identical to the black-billed magpie (Pica hudsonia) found in much of the rest of North America. The scientific name commemorates the English naturalist Thomas Nuttall.
The black-billed magpie, also known as the American magpie, is a bird in the corvid family found in the western half of North America. It is black and white, with the wings and tail showing black areas and iridescent hints of blue and blue-green. It was once thought to be a subspecies of the Eurasian magpie, but was placed into its own species in 2000 based on genetic studies.
The Eurasian magpie or common magpie 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. In Europe, "magpie" is used by English speakers as a synonym for the Eurasian magpie: the only other magpie in Europe is the Iberian magpie, which is limited to the Iberian Peninsula. Despite having a shared name and similar colouration, it is not closely related to the Australian Magpie.
The passerine birds of the genus Aphelocoma include the scrub jays and their relatives. They are New World jays found in Mexico, western Central America and the western United States, with an outlying population in Florida. This genus belongs to the group of New World jays–possibly a distinct subfamily–which is not closely related to other jays, magpies or treepies. They live in open pine-oak forests, chaparral, and mixed evergreen forests.
Pica is a genus of seven species of birds in the family Corvidae in both the New World and the Old.
Formicariidae is a family of smallish suboscine passerine birds of subtropical and tropical Central and South America known as antthrushes. They are between 10 and 20 cm in length, and are most closely related to the ovenbirdss in the family Furnariidae, and the tapaculos in the family Rhinocryptidae. The family Formicariidae contains 12 species in two genera.
The pink robin is a small passerine bird native to southeastern Australia. Its natural habitats are cool temperate forests of far southeastern Australia. Like many brightly coloured robins of the family Petroicidae, it is sexually dimorphic. Measuring 13.5 cm (5.3 in) in length, the robin has a small, thin, black bill, and dark brown eyes and legs. The male has a distinctive white forehead spot and pink breast, with grey-black upperparts, wings and tail. The belly is white. The female has grey-brown plumage. The position of the pink robin and its Australian relatives on the passerine family tree is unclear; the Petroicidae are not closely related to either the European or American robins, but appear to be an early offshoot of the Passerida group of songbirds.
The black-rumped magpie is a species of magpie found in central Bhutan to west-central China. It was formerly classified as a subspecies of the Eurasian magpie.
The Asir magpie, also known as the Arabian magpie, is a highly endangered species of magpie endemic to Saudi Arabia. It is only found in the country's southwestern highlands, in the Asir Region. It occurs only in African juniper forest in well-vegetated wadis and valleys. It was formerly classified as a subspecies of the Eurasian magpie, and still is by many authorities. This species is highly threatened by habitat destruction, as its native forests are not regenerating. Tourism development and climate change are also posing a threat. Only 135 pairs are known to survive in the wild, and this number is declining.
The Maghreb magpie is a species of magpie found in North Africa from Morocco east to Tunisia. It can be distinguished from the Eurasian magpie by the patch of blue skin behind its eye, the narrower white belly, the shorter wings, and the longer tail.
