About These Birds
黑冠鹃隼
The Black Baza is a small, striking raptor of South and Southeast Asia with a bold crest, black upperparts, and white underparts barred with chestnut. It inhabits tropical and subtropical forests, including forest edges and secondary growth, from the foothills of the Himalayas through Myanmar, southern China, and the Malay Peninsula. It feeds primarily on large insects, frogs, and lizards, often hunting in small groups.
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.
