A bald eagle's white head may make it look bald. But actually the name comes from an old English word, "balde," meaning white. These graceful birds have been the national symbol of the United States since 1782.
Female bald eagles are a bit bigger than males. Their bodies can be three feet (one meter) long, and their wingspan can be eight feet (2.4 meters) across. That's about the distance from the floor to the ceiling!
Babies, called eaglets, are born light gray then turn brown. When they are four to five years old, they develop their normal white heads and tails. In the wild, they can live to be 35 years old or more.
