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.
Resplendent Quetzal
The resplendent quetzal was considered divine by the Maya and Aztec civilizations, associated with the feathered serpent god Quetzalcoatl. Its iridescent green plumage and long tail streamers make it one of the most beautiful birds in the world. Guatemala's currency is named after this bird.
