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 Eagle-Owl
The Eurasian eagle-owl is one of the largest owl species in the world, with females sometimes reaching a wingspan of nearly two meters. Its deep booming call can be heard up to four kilometers away on calm nights. These apex predators sit at the top of the avian food chain, preying on other raptors including buzzards and smaller owls.
