Griffon Vulture only
Rock Pigeon only
Griffon Vulture
Mountains, cliffs, and open grasslands. Nests on cliff ledges in colonies. Requires thermals for soaring flight.
Rock Pigeon
Originally cliff-nesting in Mediterranean regions. Now the quintessential urban bird, inhabiting cities worldwide on every continent.
Song & Call Comparison
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.
Rock Pigeon
Soft, rhythmic cooing 'roo-c'too-coo' repeated multiple times, with emphasis on second syllable. Male courtship coo is deeper and more persistent. Wing-clapping on takeoff is loud.
Geographic Range & Migration
Griffon Vulture
Southern Europe, North Africa, the Middle East, and Central Asia. Resident in most of its range.
Rock Pigeon
Native to Europe, North Africa, and South Asia. Feral populations on every continent except Antarctica.

Hooked yellowish bill adapted for tearing carrion
Rock Pigeon
Wild-type has a blue-grey body with iridescent green and purple neck feathers, two black wing bars, and a white rump. Feral populations show enormous color variation.

About These Birds
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.
Rock Pigeon
The rock pigeon is the ancestor of all domestic pigeon breeds and one of the most abundant birds in cities worldwide. Pigeons have served humans as messengers, food, and subjects for scientific research — their homing ability and vision have been studied extensively. Darwin's study of pigeon breeding contributed to his theory of evolution.
