About These Birds
兀鹫
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.
黑鸢
黑鸢（约900克）是世界上数量最多的猛禽之一，广布于欧洲、亚洲、非洲和澳大拉西亚。尾羽呈浅叉形，具有高度的杂食性和食腐性。以腐肉、垃圾和小型脊椎动物为食，在非洲城市中极为常见。无危；种群数量庞大，适应性极强。
