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.
European Goldfinch
The European goldfinch is a strikingly beautiful finch whose tinkling song and colorful plumage have made it popular in art and as a caged bird for centuries. It appears frequently in Renaissance paintings as a symbol of the Passion of Christ. Flocks of goldfinches are charmingly called a charm.
