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.
European Roller
The European roller gets its name from the spectacular rolling and tumbling aerial displays performed by males during courtship. It is the only roller species in Europe and one of the continent's most colorful birds. Declining across much of its western range due to agricultural intensification and habitat loss.
