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.
Resplendent Quetzal
The resplendent quetzal was considered divine by the Maya and Aztec civilizations, associated with the feathered serpent god Quetzalcoatl. Its iridescent green plumage and long tail streamers make it one of the most beautiful birds in the world. Guatemala's currency is named after this bird.
