About These Birds
Blue Jay
アオカケスは鮮やかな羽毛と大きな鳴き声で知られるカラス科の大胆で知能が高い鳥。アオカケスは毎秋数千個のドングリを蓄えることでカシの木の重要な散布者となっている。複雑な社会的行動には、給餌器から他の鳥を追い払うためにタカの声を真似ることも含まれる。
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.
