Eurasian magpie or common 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 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.

The Eurasian magpie is almost identical in appearance to the North American black-billed magpie (Pica hudsonia) and at one time the two species were considered to be conspecific.[ In 2000, the American Ornithologists' Union decided to treat the black-billed magpie as a separate species based on studies of the vocalization and behaviour that indicated that the black-billed magpie was closer to the yellow-billed magpie (Pica nuttalli) than to the Eurasian magpie

 

Etymology

The prefix "mag" dates from the 16th century and comes from the short form of the given name Margaret, which was once used to mean women in general (as Joe or Jack is used for men today); the pie's call was considered to sound like the idle chattering of a woman, and so it came to be called the "Mag pie". "Pie" as a term for the bird dates to the 13th century, and the word "pied", first recorded in 1552, became applied to other birds that resembled the magpie in having black-and-white plumage.

 

Feeding

 

The magpie is omnivorous, eating young birds and eggs, small mammals, insects, scraps and carrion, acorns, grain, and other vegetable substances.

 

Intelligence

 

The Eurasian magpie is believed to be not only among the most intelligent of birds, but also among the most intelligent of all animals. Along with the western jackdaw, the Eurasian magpie's nidopallium is approximately the same relative size as those in chimpanzees and humans and significantly larger than the gibbons. Like other corvids, such as ravens and crows, their total brain-to-body mass ratio is equal to most great apes and cetaceans. A 2004 review suggests that the intelligence of the corvid family to which the Eurasian magpie belongs is equivalent to that of the great apes (chimpanzees, bonobos, gorillas and orangutans) in terms of social cognition, causal reasoning, flexibility, imagination and prospection.

 

Magpies have been observed engaging in elaborate social rituals, possibly including the expression of grief. Mirror self-recognition has been demonstrated in European magpies, making them one of only a few species known to possess this capability. The cognitive abilities of the Eurasian magpie are regarded as evidence that intelligence evolved independently in both corvids and primates. This is indicated by tool use, an ability to hide and store food across seasons, episodic memory, and using their own experience to predict the behavior of conspecifics. Another behaviour exhibiting intelligence is cutting their food in correctly sized proportions for the size of their young. In captivity, magpies have been observed counting up to get food, imitating human voices, and regularly using tools to clean their own cages. In the wild, they organise themselves into gangs and use complex strategies hunting other birds and when confronted by predators.

 

Status

 

The Eurasian magpie has an extremely large range. The European population is estimated to be between 7.5 and 19 million breeding pairs. Allowing for the birds breeding in other continents, the total population is estimated to be between 46 and 228 million individuals. The population trend in Europe has been stable since 1980. There is no evidence of any serious overall decline in numbers, so the species is classified by the International Union for Conservation of Nature as being of Least Concern.
