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 Starling
The common starling is famous for its murmurations — vast swirling flocks of thousands that create mesmerizing patterns in winter skies. An accomplished mimic, it can imitate other birds, car alarms, and phone ringtones. Introduced to North America by a group intent on establishing every bird mentioned by Shakespeare.
