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.
Emperor Penguin
The emperor penguin is the tallest and heaviest of all penguin species. They breed in the harshest conditions on Earth, enduring Antarctic winter temperatures of -60 C and wind speeds of 200 km/h. Males incubate the single egg on their feet under a brood pouch for about 65 days while fasting.
