The adult bald eagle is a large dark brown bird with a white head and tail and yellow bill, eyes, legs and feet. The female is larger than the male by as much as 25 percent.
Common names[ edit ] The common names for various birds of prey are based on structure, but many of the traditional names do not reflect the evolutionary relationships between the groups.
Variations in shape and size Eagles tend to be large birds with long, broad wings and massive feet. Booted eagles have legs and feet feathered to the toes and build very large stick nests.
Ospreysa single species found worldwide that specializes in catching fish and builds large stick nests. Kites have long wings and relatively weak legs. They spend much of their time soaring. They will take live vertebrate prey, but mostly feed on insects or even carrion. The true hawks are medium-sized birds of prey that usually belong to the genus Accipiter see below.
They are mainly woodland birds that hunt by sudden dashes from a concealed perch. They usually have long tails for tight steering.
Buzzards are medium-large raptors with robust bodies and broad wings, or, alternatively, any bird of the genus Buteo also commonly known as "hawks" in North America, while "buzzard" is colloquially used for vultures.
Harriers are large, slender hawk-like birds with long tails and long thin legs. Most use a combination of keen eyesight and hearing to hunt small vertebrates, gliding on their long broad wings and circling low over grasslands and marshes.
Vultures are carrion-eating raptors of two distinct biological families: Members of both groups have heads either partly or fully devoid of feathers. Falcons are medium-size birds of prey with long pointy wings.
They belong to the Falconidae family, rather than the Accipitridae accipiters. Many are particularly swift flyers. Caracaras are a distinct subgroup of the Falconidae unique to the New Worldand most common in the Neotropics — their broad wings, naked faces and appetites of a generalist suggest some level of convergence with either the Buteos or the vulturine birds, or both.
|Search form||Oriental honey-buzzard Pernis ptilorhyncus Accipitrids are predominantly predators and most species actively hunt for their prey. Prey is usually captured and killed in the powerful talons of the raptor and then carried off to be torn apart with a hooked bill for eating or feeding to nestlings.|

|Today's selected stories||Eagles are large birds of prey. Hawks are birds of prey that are usually smaller in size and weight less.|
Owls are variable-sized, typically night-specialized hunting birds. They fly almost silently due to their special feather structure that reduces turbulence.
They have particularly acute hearing. Many of these English language group names originally referred to particular species encountered in Britain. As English-speaking people travelled further, the familiar names were applied to new birds with similar characteristics. Names that have generalised this way include: Some names have not generalised, and refer to single species or groups of closely related sub species: Historical classifications[ edit ] The taxonomy of Carl Linnaeus grouped birds class Aves into orders, genera, and species, with no formal ranks between genus and order.
He placed all birds of prey into a single order, Accipitres, subdividing this into four genera: Vultur vulturesFalco eagles, hawks, falcons, etc. This approach was followed by subsequent authors such as Gmelin, Latham, and Turnton.
Louis Pierre Veillot used additional ranks: In addition to the original Vultur and Falco now reduced in scopeVeillot adopted four genera from Savigny: Bald eagle The order Accipitriformes is believed to have originated 44 million years ago when it split from the common ancestor of the secretarybird Sagittarius serpentarius and the accipitrid species.May 26, · Cape Vulture vs pair of Tawny Eagles or immature Bateleur Eagles for the top perch in a dead tree in Khutze Reserve in Botswana Bald Eagle: Haliaeetus leucocephalus Appearance: The adult bald eagle is a large dark brown bird with a white head and tail and yellow bill, eyes, legs and feet.
The female is larger than the male by as much as 25 percent. The juvenile bald eagle is mostly dark brown with dark brown eyes and a gray or black bill, but has white patches or spots on its tail, belly and under its wings.
The sea eagles also share some traits with the palmnut vulture (Gypohierax angolensis), suggesting a relationship between them and Old World vultures (Brown and Amadon, ).
Using cyt- b sequence data, Seibold and Helbig () studied eight of the nine species of sea eagles in the genus Haliaeetus. The sea eagles also share some traits with the palmnut vulture (Gypohierax angolensis), suggesting a relationship between them and Old World vultures (Brown and Amadon, ).
