Eagle

Booted Eagle
Eagles are members of the bird family Accipitridae, and belong to several genera which are not necessarily closely related to each other. Most of the more than sixty species occur in Eurasia and Africa. Outside this area, just eleven species can be found - two species (the Bald Eagle and Golden Eagle) in the United States and Canada, nine species in Central America and South America, and three species in Australia.

South nicobar serpent eagle
Eagles are large, powerfully built birds of prey, with a heavy head and beak. Even the smallest eagles, like the Booted Eagle (Aquila pennata), have relatively longer and more evenly broad wings, and more direct, faster flight. Most eagles are larger than any other raptors apart from some vultures. The smallest species called eagle is the South Nicobar Serpent Eagle (Spilornis klossi), at 450 g and 40 cm long. Like all birds of prey, eagles have very large hooked beaks for tearing flesh from their prey, strong muscular legs, and powerful talons. The beak is typically heavier than most other birds of prey.


Some types of eagle are :


- Bald Eagle (Haliaeetus leucocephalus)

Bald Eagle
the bald eagle is a bird of prey found in North America. It is the national bird of the United States of America and appears on its Seal. This sea eagle has two known sub-species and forms a species pair with the White-tailed Eagle. Its range includes most of Canada and Alaska, all of the contiguous United States, and northern Mexico. It is found near large bodies of open water with an abundant food supply and old-growth trees for nesting. The Bald Eagle builds the largest nest of any North American bird, up to 4 meters deep, 2.5 meters wide, and 1.1 tons in weight.

Golden Eagle
- Golden Eagle (Aquila chrysaetos)

The Golden Eagle is one of the best known birds of prey in the Northern Hemisphere. Like all eagles, it belongs to the family Accipitridae. Once widespread across the Holarctic, it has disappeared from many of the more heavily populated areas. Despite being extirpated from or uncommon in some its former range, the species is still fairly ubiquitous, being present in Eurasia, North America, and parts of Africa. The highest density of nesting Golden Eagles in the world lies in southern Alameda County, California. These birds are dark brown, with lighter golden-brown plumage on their heads and necks.

- Harpy Eagle (Harpia harpyja)
Harpy Eagle

The Harpy Eagle , sometimes known as the American Harpy Eagle, is a Neotropical species of eagle. It is the largest and most powerful raptor found in the Americas, and among the largest extant species of eagles in the world. It usually inhabits tropical lowland rainforests in the upper (emergent) canopy layer. Destruction of its natural habitat has seen it vanish from many parts of its former range, and it is almost extinct in Central America.

Crowned Solitary Eagle
- Crowned Solitary Eagle (Buteogallus coronatus)

The Crowned Solitary Eagle, typically known simply as the Crowned Eagle (leading to potential confusion with the African Stephanoaetus coronatus) is an endangered bird of prey from eastern and central South America. This is a large raptor with a length of 73–79 cm, a wingspan of 170–183 cm  and an average weight of 2.95 kg. Adults are almost entirely gray with a large occipital crest and a short, black-and-white-banded tail. The juvenile is gray-brown on the back and pale with gray-brown streaks on the head and underside.

- Black-chested Buzzard Eagle (Geranoaetus melanoleucus)

Black-chested Buzzard Eagle
The Black-chested Buzzard-Eagle is a bird of prey of the hawk and eagle family (Accipitridae). It lives in open regions of South America. This species is also known as the Black Buzzard-eagle, Grey Buzzard-eagle or analogously with "eagle" or "eagle-buzzard" replacing "buzzard-eagle", or as the Chilean Blue Eagle. It is sometimes placed in the genus Buteo.This is a huge eagle-like "buzzard" ("hawk" in American terminology). It has a total length of 60–80 cm and a wingspan of 149–200 cm. In the smaller G. m. australis subspecies, the weight is 1.7-3.2 kg, with no reported weights on the nominate subspecies.
