About These Birds
American Crow
The American crow is one of North America's most familiar and intelligent birds. Research has shown they can recognize individual human faces and communicate perceived threats to other crows. They form large winter roosts of up to hundreds of thousands of individuals in some cities.
Eurasian Magpie
The Eurasian magpie is one of the most intelligent animals on Earth and the first non-mammal demonstrated to recognize itself in a mirror. These bold corvids build elaborate domed nests of sticks and have a well-known attraction to shiny objects, though this reputation may be exaggerated.
