About These Birds
Great Cormorant
The great cormorant is one of the most widespread seabirds in the world. Unlike most waterbirds, cormorants lack fully waterproof plumage, leading to the iconic pose of standing with wings spread open to dry. In Asia, cormorants have been used by fishermen to catch fish for over a thousand years.
角雕
角雕是美洲最大的猛禽之一，翼展可达224厘米。头部具灰白色双羽冠，体羽黑白对比分明，爪极为强大有力。分布于墨西哥至玻利维亚的热带低地雨林，以树栖哺乳动物为主食，包括树懒和猴子。飞行速度快，是雨林顶级捕食者。
