Size Comparison
Habitat Comparison
عقاب رخماء
Large bodies of open water including coasts, rivers, and lakes with abundant fish and old-growth trees for nesting.
نسر أسمر
Mountains, cliffs, and open grasslands. Nests on cliff ledges in colonies. Requires thermals for soaring flight.
Song & Call Comparison
عقاب رخماء
High-pitched, chattering whistle: a rapid 'kleek-kik-ik-ik-ik'. Surprisingly weak and thin for such a large raptor. Also gives a lower 'kwit-kwit' call near the nest.
نسر أسمر
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
عقاب رخماء
North America from Alaska and Canada through the contiguous United States to northern Mexico.
نسر أسمر
Southern Europe, North Africa, the Middle East, and Central Asia. Resident in most of its range.

About These Birds
عقاب رخماء
The bald eagle is the national bird and symbol of the United States. Once endangered due to DDT pesticide use, it made a remarkable recovery and was removed from the endangered species list in 2007. These powerful raptors build the largest tree nests of any bird, some weighing over two tons.
نسر أسمر
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.
