An introduction to Eagles

Facts

The term 'eagle' does not refer to any scientifically recognised group of birds. Eagles can generally be divided into six main groups - True Eagles, Sea eagles, Booted eagles, Hawk eagles, Snake Eagles and Specialist Eagles.
There are about 60 species in the world. True eagles come from the genus Aquila, which is Latin for eagle. There are 10 species within this genus, which includes the Golden Eagle of Europe, Asia and North America, the Tawny Eagle of Africa and Asia, and the Wedge-tailed Eagle of Australia. Aquiline eagles are absent from South America, where eagles of other genera take their place.

Features

The features of eagles vary tremendously. As a result, many are not closely related to others. Most eagles have feathered legs although some have bare legs. Almost all eagles have broad wings. They range in size from small to exceptionally large. The largest species can weigh almost 2Olbs (9kg). Regardless of size, eagles usually have a powerful build.

General

There are several specialised eagles throughout the world. They are very large to huge and are some of the most advanced birds of prey in the world. Another widely distributed genus (except for South America) is Haliaeetus. which is Greek for Sea Eagle. These are some of the larger eagles in the world. They eat a large amount of fish, have powerful toes and talons, and usually a loud, raucous call. The Osprey has similar habits to the fish eagles, although it is not closely related to them. This species is usually classified into the broad hawks and relations group but it is in a family all of its own (Pandionidae). It is a very successful raptor and can be found on every continent.
Although many eagles are very predatory, a large number of species will eat carrion regularly.
One of the most widely distributed (and successful) eagles in the world is the Golden Eagle. Despite being capable of catching a wide variety of prey, this species will consume large amounts of carrion and make use of most available food sources.
Throughout history, eagles have been used as symbols of power and strength. The Romans used to march under the banner of an Imperial Eagle. Another well-known eagle is the Bald Eagle. Apart from being the national emblem of the United States, this species is also a very powerful symbol for native North Americans.
