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.
Great Cormorant
The great cormorant is one of the most widespread seabirds in the world. Unlike most waterbirds, cormorants lack fully waterproof plumage, leading to the iconic pose of standing with wings spread open to dry. In Asia, cormorants have been used by fishermen to catch fish for over a thousand years.
