Eurasian Magpie

Pica pica

The Eurasian Magpie, European Magpie, or Common Magpie, (Pica pica), is a resident breeding bird throughout Europe, much of Asia and northwest Africa. It is one of several birds in the crow family named as magpies, and belongs to the Holarctic radiation of "monochrome" magpies. In Europe, "Magpie" is used by English speakers as a synonym for the European Magpie; it is the only magpie in Europe outside the Iberian Peninsula.

The Eurasian Magpie is one of the most intelligent birds, and it is believed to be one of the most intelligent of all animals. The expansion of its neostriatum is approximately the same in its relative size as is found in chimpanzees, orangutans and humans.

The Eurasian Magpie is 44-46 centimetres (17-18 in) in length - in the adult over 50% of this is tail - and a wingspan of 52-62 centimetres (20-24 in). Its head, neck and breast are glossy black with a metallic green and violet sheen; the belly and scapulars (shoulder feathers) are pure white; the wings are black glossed with green or purple, and the primaries have white inner webs, conspicuous when the wing is open. The graduated tail is black, shot with bronze-green and other iridescent colours. The legs and bill are black.

The young resemble the adults, but are at first without much of the gloss on the sooty plumage. The male is slightly larger than the female.

There are numerous subspecies. The northwest African race differs in having a patch of blue bare skin around the eye, no white patch on the rump and an unglossed tail. The southwest Arabian race differs in being smaller, with dull black plumage lacking iridescent tones, and minimal white in the wings. The Siberian races have more extensive white in the wings, and brilliant green iridescence; Korean birds have a purple gloss instead and relatively longer wings and a shorter tail.

Analysis of mtDNA sequences has indicated that the Korean race, P. pica sericea, is very distinct from the other Eurasian forms, and may be a separate species. The North American Black-billed Magpie which looks almost identical to the Eurasian form and was previously considered conspecific is genetically closer to the Yellow-billed Magpie. The main Eurasian lineages of this astoundingly variable species have not been sufficiently sampled to clarify the status of such forms as the northwest African race P. p. mauretanica and the southwest Arabian race P. p. asirensis, which could also be distinct species.

A larger palaeosubspecies of the European Magpie was described as Pica pica major.
