About These Birds
pygargue à tête blanche
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.
Circaète à poitrine noire
The Black-chested Snake-eagle is a large, powerful raptor of sub-Saharan African open habitats, with dark brown upperparts, a white belly, and a conspicuous black breast forming a dark chest band. It inhabits open and lightly wooded savanna, grasslands, and semi-arid scrub across much of eastern and southern Africa. As its name suggests, it feeds almost exclusively on snakes and other reptiles.
