The Bald Eagle is a bird of prey found in North America that is most recognizable as the national bird and symbol of the United States. This sea eagle has two known sub-species and forms a species pair with the White-tailed Eagle. Its range includes most of Canada and Alaska, all of the contiguous United States, and northern Mexico. It is found near large bodies of open water with an abundant food supply and old-growth trees for nesting.The plumage of an adult Bald Eagle is evenly brown with a white head and tail. The tail is moderately long and slightly wedge-shaped. Males and females are identical in plumage coloration, however females display reverse sexual dimorphism and are 25 percent larger than males. The beak, feet, and irises are bright yellow. The legs are unfeathered, and the toes are short and powerful with long talons. The highly developed talon of the hind toe is used to pierce the vital areas of prey while it is held immobile by the front toes. The beak is large and hooked, with a yellow cere.Bald Eagles feed primarily on fish, but also eat small animals (ducks, coots, muskrats, turtles, rabbits, snakes, etc.) and occasional carrion (dead animals). They swoop down to seize fish in their powerful, long and sharp talons (approximately 1,000 pounds of pressure per square inch in each foot). They can carry their food off in flight, but can only lift about half their weight. Bald Eagles have been recorded at 44 miles per hour in level flight. They seldom dive vertically on their prey, preferring to decend more gradually and snatch fish, rabbits, etc. with their feet. Their diving speed is estimated at 75 to 100 miles per hour. They can fly to altitudes of 10,000 feet or more, and can soar aloft for hours using natural wind currents and thermal updrafts. Bald Eagles can swim to shore with a heavy fish using their strong wings as paddles. However, it is also possible that they can drown if the fish weighs too much.Bald eagles were officially declared an endangered species in 1967 in all areas of the United States south of the 40th parallel, under a law that preceded the Endangered Species Act of 1973.Until 1995, the bald eagle had been listed as endangered under the Endangered Species Act in 43 of the 48 lower states, and listed as threatened in Wisconsin, Minnesota, Michigan, Washington and Oregon. In July of 1995, the US Fish and Wildlife Service upgraded the status of bald eagles in the lower 48 states to "threatened." On June 28, 2007 the Interior Department took the American bald eagle off the Endangered Species List. The bald eagle will still be protected by the Migratory Bird Treaty Act and the Bald and Golden Eagle Protection Act. The Bald Eagle Protection Act prohibits the take, transport, sale, barter, trade, import and export, and possession of eagles, making it illegal for anyone to collect eagles and eagle parts, nests, or eggs without a permit. Native Americans are able to possess these emblems which are traditional in their culture.
