About These Birds
Common Ostrich
ダチョウ（Struthio camelus）— 世界最大の鳥でアフリカのサバンナに生息する。飛べないが時速70kmで走ることができ、世界最大の卵を産む。
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.
