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.
百慕大鹰
The Bermuda Hawk was a large hawk that was endemic to Bermuda and became extinct shortly after human settlement of the islands in the early 17th century. Known only from subfossil bones, it was probably a broad-winged raptor that preyed on seabirds and other island fauna. Habitat destruction and hunting contributed to its extinction.
