About These Birds
águia-de-cabeça-branca
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.
Common Kingfisher
The common kingfisher is a dazzling jewel of waterways, its iridescent blue plumage caused by light refraction in the feather structure rather than pigment. These birds inspired the design of the Shinkansen bullet train in Japan — the shape of their bill was copied to reduce sonic booms when trains exit tunnels.
