About These Birds
American Crow
北米全域に広く分布する大型のカラス（体長40〜53cm）。全身光沢のある黒で、知性が高く強い社会性を持つ。Corvus brachyrhynchos（アメリカガラス）は北米で最もよく見られるカラスで、交通量の多い道路に堅い木の実を置いて車に割らせる「道具使用」が観察されている。Corvidae科。
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.
