Habitat Comparison
Môi Trường Sống Chung
Common Kestrel only
Common Kestrel
Open country including farmland, grasslands, moorland, and urban areas. Common along motorways and in cities across Europe.
Griffon Vulture
Mountains, cliffs, and open grasslands. Nests on cliff ledges in colonies. Requires thermals for soaring flight.
Song & Call Comparison
Common Kestrel
A shrill, repeated 'kee-kee-kee-kee' or 'kik-ik-ik', especially near nest. Alarm call is a nasal chattering. Generally less vocal than larger falcons. Calls ring clearly in open country.
Griffon Vulture
Generally silent; hisses and grunts at carrion with other vultures. Gives low croaking 'arrr' near nest. At colonies produces cackling and grunting — not melodic vocalizations.
Geographic Range & Migration
Common Kestrel
Europe, Asia, and Africa. One of the most common and widespread raptors in the Old World.
Griffon Vulture
Southern Europe, North Africa, the Middle East, and Central Asia. Resident in most of its range.

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.
Griffon Vulture
The griffon vulture is one of Europe's largest flying birds and a crucial scavenger in Mediterranean ecosystems. These social birds nest in large cliff colonies and can soar for hours using thermals without flapping. Vulture populations faced a crisis from the veterinary drug diclofenac, which proved fatal when consumed through contaminated carcasses.
