About These Birds
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.
Hawfinch
シメはヨーロッパの鳥の中で体の大きさに対して最も強力なくちばしを持ち、27〜43 kgの力でサクランボの種を割ることができる。その特徴的な外見にもかかわらず、著名なほど恥ずかしがり屋で観察が難しい。種割り時に発生する巨大な力を吸収するための頭骨の特殊な適応を持つ。
