Juvenile bald eagles are a mixture of brown and white. They reach full maturity in four to five years.
The female bald eagle is 35 to 37 inches, slightly larger than the male. Their wingspan ranges from 72 to 90 inches and they weigh from ten to fourteen pounds.
Bald eagles can fly to an altitude of 10,000 feet. During level flight, they can achieve speeds of about 30 to 35 mph. The beak, talons, and feathers are made of keratin, just like your finger nails.
Wild bald eagles may live as long as thirty years. An eagle’s lifting power is about 4 pounds. Their diet is mainly fish, but they will take advantage of carrion. Once paired, bald eagles remain together until one dies.
The bald eagle became the National emblem in 1782 when the great seal of the United States was adopted.
