全長は 34-39cm で、キジバトより一回り大きい程度。ただし尾羽が 20-23cm と長く、頭と体の大きさはムクドリ大。 名前の由来は、尾羽が長いことによる。
頭は黒く、背は淡い灰褐色、翼と尾は青灰色、のどから腹は灰白色で、尾の先が白い。雌雄同色である。
なお、イベリア半島に分布する亜種は尾羽の先の白斑がない。
The Azure-winged Magpie (Cyanopica cyana) is a bird in the crow family. It is 31 35 cm long and similar in overall shape to the European Magpie (Pica pica) but is more slender with proportionately smaller legs and bill. It belongs to the monotypical genus Cyanopica.
It has a glossy black top to the head and a white throat. The underparts and the back are a light grey-fawn in colour with the wings and the feathers of the long (16 20 cm) tail are an azure blue. It inhabits various types of coniferous (mainly pine) and broadleaf forest, including parks and gardens in the eastern populations.
