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.
Eurasian Wren
The Eurasian wren is one of the smallest birds in Europe but possesses an astonishingly loud song for its size. Males build multiple dome-shaped nests, from which the female selects one to line and use. In British folklore, the wren is known as the king of birds for outwitting the eagle in a flying contest.
