A surprisingly deep, resonant croaking 'kowrr-kowrr' often heard at dawn on African savannas. Also gives pig-like grunting sounds. Mostly silent compared to true songbirds.

About These Birds
đại bàng đầu trắng
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.
Diều ăn rắn
The secretary bird is the only raptor that hunts primarily on foot, striding through grasslands on crane-like legs up to 1.2 meters tall. Its name may derive from the crest feathers resembling quill pens tucked behind a secretary's ear. The species is classified as Endangered due to habitat loss and decline across much of its range.
