How to Tell a Female Bald Eagle From a Male Bald Eagle

The bald eagle is our national emblem. This proud bird reflects America̵7;s strength, freedom and loyalty. The bird is not actually bald; it is called this because of its white feathers on its head. The bald eagle selects a mate and they are together for life. This great bird does not have many natural enemies; sometimes the horned owl or an occasional raccoon can threaten them, but humans are its worst enemies. Male and female bald eagles are almost identical in appearance, but there are a couple of ways to tell the difference.
