FUN FACTS

1. Eagles are often further divided into four categories depending on diet and physical features. Some examples include:

true or booted eagles - "booted" is a reference to the leg feathers, which extend all the way down to the toes. Golden eagles (Aquila chrysaetos) are a type of true or booted eagle.

harpy eagles - the six types of harpy eagles can be identified by the crests on their heads.

fish eagles - diet is mainly fish. Bald eagles (Haliaeetus leucocephalus) are a type of fish eagle, but their diet also consists of birds and small mammals. In addition, bald eagles are scavengers that harass other birds and steal their fish.

snake eagles - diet includes a variety of snakes. Bateleur eagles (Terathopius ecuadatus) are snake eagles

ECOLOGY AND CONSERVATION

Benjamin Franklin was opposed to the idea of choosing the bald eagle as the national bird of the United States, possibly because of their scavenging nature. Franklin favored the wild turkey instead. Despite his argument that the wild turkey was more important to American settlers, the bald eagle was declared the national bird of the United States in 1782. But human activities such as pesticide contamination and hunting caused a severe decline in its numbers. Although protected by several laws, including the Endangered Species Act, the bald eagle faced extinction. Finally, the trends were reversed, the populations recovered, and the bald eagle was officially removed from the Endangered Species List in 1999.
