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.
Wilson's Bird-of-paradise
Wilson's bird-of-paradise is one of the most extraordinarily colored birds on Earth. Males meticulously clear a patch of forest floor as a display court, removing every leaf and twig. The species was virtually unknown to science until the late 20th century due to its restricted island range.
