Bald Eagle - Saved US national symbol

The Bald eagle is United States of America's' national symbol of strength and freedom. It almost become nothing but mere memory in 1970's when there were only 500 breeding pairs left in existence. But strong federal protection and especially ban on the use of pesticide DDT helped a lot in this beautiful bird recovery as now there are more than 7,500 breeding pairs and was officially removed from the List of Endangered and Threatened Wildlife on June 28, 2007.

The bald eagle is very large bird with a body length up to 1m, and a wingspan that could reach even 250 cm. Surprisingly females are about 25 % larger than males. Adult bald eagles have brown body and white head while youngsters are completely brown.

The bald eagle prefers habitats near seacoasts, rivers, large lakes, and other large bodies of open water with an abundance of fish. These birds are very sensitive to human activity and therefore have their habitats in areas where there is no human population or where the human population is low..

Therefore it is best for bald eagles (as for many other animals too) not to be interfered with human activity in their habitats, or when this is not possible to limit human activity as much as possible because results of many studies showed that human activity often does terrible things to animal habitats.
