Eagle

The bald eagle, with its snowy-feathered (not bald) head and white tail, is the proud national bird symbol of the United States—yet the bird was nearly wiped out there. For many decades, bald eagles were hunted for sport and for the "protection" of fishing grounds. Pesticides like DDT also wreaked havoc on eagles and other birds. These chemicals collect in fish, which make up most of the eagle's diet. They weaken the bird's eggshells and severely limited their ability to reproduce. Since DDT use was heavily restricted in 1972, eagle numbers have rebounded significantly and have been aided by reintroduction programs. The result is a wildlife success story—the U.S. Fish and Wildlife Service has upgraded the birds from endangered to least concern.

Description
The majestic Eagle has been used to symbolize courage and power in many cultures, and for good reason. Its large size and superb aerial skills define this animal as the most powerful flying animal available in your army. Females attain a length of about 1 yard (1 meter) from tip of the beak to the tip of the tail, and have a wingspan of about 2 yards (2 meters). Males are smaller, as is true for most birds of prey. The Eagle makes for a great scout combination because it has one of the highest sight radiuses of all of the animals available to you.
