About These Birds
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.
Bat Hawk
The Bat Hawk is a medium-sized raptor found across sub-Saharan Africa and parts of Southeast Asia, inhabiting forest edges and open woodland near water. It is specially adapted for crepuscular hunting, with large eyes and a remarkably wide gape that allows it to swallow bats and swifts whole in flight. Its dark brown plumage and swift, agile flight make it well-suited to hunting in dim light at dusk and dawn.
