About These Birds
Common Kestrel
The common kestrel is Europe's most abundant falcon, famous for its ability to hover motionless in the wind while scanning for prey. Research has shown kestrels can see ultraviolet light, allowing them to detect vole urine trails that reflect UV. The species has adapted remarkably well to urban environments.
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.
