Iberian magpie

The Iberian magpie (Cyanopica cooki) is a bird in the crow family. It is 31–35 cm long and similar in overall shape to the Eurasian magpie (Pica pica) but is more slender with proportionately smaller legs and bill. It belongs to the genus Cyanopica.

Other common names include Iberian azure-winged magpie,[1] Cook's azure-winged magpie and Spanish azure-winged magpie.[2]

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.

Distribution and habitat

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,[3] and recently its presence has been reported even in northern Italy.[4] This taxon is usually treated as conspecific with azure-winged magpie C. cyana, but this population is 5400 miles (9,000 km) away from those in eastern Asia.[2] Recent genetic analysis has shown that the Iberian magpie and the azure-winged magpie are distinct at species level.[5]

Behaviour and ecology

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.[6] There are usually 6–8 eggs that are incubated for 15 days.[7]

gollark: See, this is bad because it presumably runs below 3GB/s.
gollark: Maybe it would be easier to just run it a lot, and calculate the time complexity.
gollark: I can't actually understand this.
gollark: Strassen, then?
gollark: I assumed that the only entry not doing that (or calling out to external stuff which did ???) was mine, which did an equally inefficient algorithm in a weird recursive way.
