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.
Emu
The emu is the second-tallest living bird and the largest bird native to Australia. It is the only bird with calf muscles, enabling powerful running at up to 50 km/h. In the famous Emu War of 1932, the Australian military was deployed against crop-raiding emus — and the emus arguably won.
