About These Birds
Betet alap-alap
The cockatiel is the smallest member of the cockatoo family and one of the most popular pet birds globally. These gentle, intelligent parrots can learn to whistle tunes and mimic sounds. Wild cockatiels are nomadic, traveling in flocks following food and water availability across the Australian outback.
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.
