About These Birds
elang botak
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.
Black Swan
The black swan was once considered impossible by Europeans who believed all swans were white, making it a famous philosophical example of inductive reasoning failure. It is the state emblem of Western Australia. Black swans form lifelong pair bonds and both parents share in incubation and care of cygnets.
