About These Birds
European Roller
ヨーロッパで最も色彩豊かな鳥の一つで、求愛時にローリングと呼ばれる独特の空中飛翔を行う。
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.
