About These Birds
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.
Northern Cardinal
The northern cardinal is the state bird of seven US states, more than any other species. Unlike many songbirds, both males and females sing, often in duets. Cardinals do not migrate and their brilliant red plumage against winter snow makes them a favorite among backyard birdwatchers.
