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

The bald eagle is our national emblem. This proud bird reflects America'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.

Things You'll Need

• Measuring tape
• Scales

Instructions

1. Weigh the bird. The female is usually slightly larger than the male of the species according to Baldeagle.org. The average weight of the female at adulthood is 11 ½ pounds and the male is 9 ½ pounds.

2. Measure the wingspan, typically the males wings when stretched to their full breadth are 6 feet and 8 inches and the female is 7 feet and 3 inches.

3. Measure the eagle's bill. The female bald eagle has a slightly longer bill than the male.

4. Check the size of the rear claws; these are called the hallux talons. The female's rear claws will be larger.
