Habitat Comparison
Common Raven
Diverse habitats from Arctic tundra to deserts, mountains, forests, and coastlines. Avoids dense urban areas but thrives near human activity.
シロエリハゲワシ
Mountains, cliffs, and open grasslands. Nests on cliff ledges in colonies. Requires thermals for soaring flight.
Song & Call Comparison
Common Raven
Highly varied: deep resonant 'kraa-kraa-kraa', hollow 'tok-tok', liquid 'klonk', and wing-whooshing. Among the most intelligent corvid callers; uses calls contextually in groups.
シロエリハゲワシ
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.

Holarctic distribution across North America, Europe, Asia, and North Africa. The most widely distributed corvid.
シロエリハゲワシ
Southern Europe, North Africa, the Middle East, and Central Asia. Resident in most of its range.

About These Birds
Common Raven
ワタリガラス（Corvus corax）— 北半球に広く分布する最大のスズメ目の鳥。高い知性をもち、道具を使うことや問題解決能力が知られている。
シロエリハゲワシ
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.
