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.
Red-crowned Crane
The red-crowned crane is one of the rarest crane species and a potent symbol of longevity and fidelity in East Asian culture. Their elaborate unison call and dancing displays have inspired art and folklore for millennia. The resident population on Hokkaido, Japan, recovered from about 33 birds in 1952 to over 1,800 today.
