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 Ostrich
The common ostrich is the world's largest living bird, standing up to 2.7 meters tall and weighing up to 145 kg. Despite being flightless, it is the fastest bird on land, sprinting at speeds up to 70 km/h. Ostrich eggs are the largest of any living bird, weighing about 1.4 kg each.
