The Eurasian magpie or common magpie (Pica pica) 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 (Cyanopica cooki), 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 Eurasian magpie is one of the most intelligent birds, and it is believed to be one of the most intelligent of all non-human animals. The expansion of its nidopallium is approximately the same in its relative size as the brain of chimpanzees, gorillas, orangutans and humans. It is the only bird known to pass the mirror test, along with very few other non-avian species.
The range of the magpie extends across temperate Eurasia from Portugal, Spain and Ireland in the west to the Kamchatka Peninsula.
The preferred habit is open countryside with scattered trees and magpies are normally absent from treeless areas and dense forests. They sometimes breed at high densities in suburban settings such as parks and gardens. They can often be found close to the centre of cities.
Magpies are normally sedentary and spend winters close to their nesting territories but birds living near the northern limit of their range in Sweden, Finland and Russia can move south in harsh weather.
