The Iberian magpie (Cyanopica cooki) is a bird in the crow family. It is 31–35 cm (12–14 in) long and similar in overall shape to the Eurasian magpie (Pica pica) but is slenderer with proportionately smaller legs and bill. It belongs to the genus Cyanopica.
This taxon was formerly treated as conspecific with the azure-winged magpie (C. cyana), but this population is 5,400 miles (9,000 km) away from those in eastern Asia.[9] Genetic analysis has suggested that Iberian and azure-winged magpies are distinct species.[10][11] Other common names include Iberian azure-winged magpie,[2] Cook's azure-winged magpie, and Spanish azure-winged magpie.[9]
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.
The Iberian magpie occurs in southwestern and central parts of the Iberian Peninsula, in Spain and Portugal. However, it can sometimes be spotted also in south-western France,[12] and recently its presence has been reported even in north-western Italy.[13] It inhabits various types of coniferous (mainly pine) and broadleaf forest, including parks and gardens in the eastern populations.
Often Iberian magpies find food as a family group or several groups making flocks of up to 70 birds. The largest groups congregate after the breeding season and throughout the winter months. Their diet consists mainly of acorns (oak seeds) and pine nuts, extensively supplemented by invertebrates and their larvae, soft fruits and berries, and also human-provided scraps in parks and towns.
This species usually nests in loose, open colonies with a single nest in each tree,[14] same mean clutch size is 6.2 eggs, but only 32% of nesting attempts are successful, with an average 5.1 young fledged.[15]
