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.
短尾雕
The Bateleur is an Endangered eagle of the family Accipitridae found in open savanna and woodland across sub-Saharan Africa. Weighing about 2,400g with an impressive wingspan of 100.1cm, it is distinguished by its extremely short tail and vivid red facial skin and bill. It soars for hours over vast distances, feeding primarily on carrion and occasionally taking live prey.
