About These Birds
عقاب رخماء
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.
مرزة سوداء
The Black Harrier is an endangered, medium-sized raptor endemic to southern Africa with almost entirely black plumage, bold white barring on the tail, and characteristic pale eyes. It inhabits lowland fynbos, Renosterveld, and wetland edges primarily in the Western and Northern Cape provinces of South Africa. It hunts by quartering low over open terrain, capturing small mammals, birds, reptiles, and insects.
