Size Comparison
Habitat Comparison
兀鹫
Mountains, cliffs, and open grasslands. Nests on cliff ledges in colonies. Requires thermals for soaring flight.
白尾海雕
Coastlines, large lakes, and rivers with mature trees or cliffs for nesting. Requires large undisturbed areas.
Song & Call Comparison
兀鹫
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.
白尾海雕
High-pitched, yelping 'klee-klee' and deep barking 'ra-ra-ra'. Less vocal than Bald Eagle but similar chattering quality. Gives gull-like wailing near nest in breeding season.
Geographic Range & Migration
兀鹫
Southern Europe, North Africa, the Middle East, and Central Asia. Resident in most of its range.
白尾海雕
Northern Europe and Asia from Greenland and Scandinavia to Japan. Reintroduced to Scotland and Ireland.

About These Birds
兀鹫
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.
白尾海雕
The white-tailed eagle is Europe's largest eagle and the fourth-largest eagle in the world. Once extinct in Britain, it has been successfully reintroduced to Scotland and Ireland through conservation programs. These powerful raptors can live over 25 years and form lifelong pair bonds.
