About These Birds
Belted Kingfisher
ミヤマカワセミは雌の方が雄よりも派手な色彩を持つという点でユニークで、赤褐色の腹帯が余分に加わっている。これらの騒々しい鳥は独特のガラガラとした鳴き声で縄張りを宣言する。重厚な嘴を使って河岸に最大2.4mもの深さの営巣穴を掘る。
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.
