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.
Bat Falcon
The Bat Falcon is a compact, fast-flying falcon found from Mexico through Central and South America to Argentina. It has slate-black upperparts, a rufous breast and belly, and a distinctive white throat patch. As its name suggests, it specializes in hunting bats at dusk, as well as swifts, swallows, and large insects caught in aerial pursuit.
