Bald Eagle Haliaeetus leucocephalus


Description

The Bald Eagle, which is our national symbol, was considered a bad choice by Benjamin Franklin because the bird sometimes steals food from other birds. He recommended the wild turkey. The Bald Eagle is an amazing bird that has survived near extinction by DDT (a type of pesticide), which causes egg shell thinning that prevents successful nesting. Today, Bald Eagle numbers are up through their protection under the Endangered Species Act and reintroduction programs using captive bred birds.

Some cool facts about this bird are:

1. It can reach speeds of up to 200 miles per hour while diving through the air.

2. The bird isn't actually bald. It has white feathers that stand out against it's overal dark plumage. Thus giving it the appearance of being bald.

3. Bald Eagles will sometimes hunt together, with one bird flushing prey towards the other.
