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.
Common Kingfisher
The common kingfisher is a dazzling jewel of waterways, its iridescent blue plumage caused by light refraction in the feather structure rather than pigment. These birds inspired the design of the Shinkansen bullet train in Japan — the shape of their bill was copied to reduce sonic booms when trains exit tunnels.
