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.
House Sparrow
The house sparrow is perhaps the most successful bird in the world at living alongside humans. Introduced to New York in 1851, it spread across North America within decades. Despite its global abundance, house sparrow populations have declined significantly in parts of western Europe.
