Song & Call Comparison

双色鹰

白头海雕

鸣唱

High-pitched, chattering whistle: a rapid 'kleek-kik-ik-ik-ik'. Surprisingly weak and thin for such a large raptor. Also gives a lower 'kwit-kwit' call near the nest.

About These Birds

双色鹰

双色鹰（Accipiter bicolor）是一种中型森林鹰，分布于从墨西哥经中美洲至玻利维亚和阿根廷的地区。上体深灰色，下体浅灰至棕褐色。属鹰科（Accipitridae），以蜥蜴和小型哺乳动物为食。

白头海雕

The bald eagle is the national bird and symbol of the United States. Once endangered due to DDT pesticide use, it made a remarkable recovery and was removed from the endangered species list in 2007. These powerful raptors build the largest tree nests of any bird, some weighing over two tons.
