About A Field Guide To The Raptors Of The World (Invited Images Only)

This group is designed to give an online version of the raptors of the world. (Not including Owls).



A bird of prey or raptor is a bird that hunts for food primarily using its talons. They display a characteristic curved tip to their beak and have superb vision.
Diurnal birds of prey belong to the orders Accipitriformes and Falconiformes in several groups including:

* Accipitriformes
o Pandionidae: Osprey
o Accipitridae: hawks, eagles, buzzards, kites and Old World vultures
o Sagittariidae: Secretary Bird
* Falconiformes
o Falconidae: falcons

For an alternative taxonomy, see also Sibley-Ahlquist taxonomy.

Nocturnal birds of prey—the owls—are separate from the diurnal families, and are in the order Strigiformes. The term "raptor" includes owls.

Although other bird groups may fill similar ecological roles and sometimes appear closely related at first sight, this is largely because of convergent evolution.

* Eagles are large birds with long, broad wings and massive legs. Booted eagles have feathered legs and build large stick nests.

* Kites have long wings and weak legs. They spend much of their time soaring. They will take live prey but mostly feed on carrion.

* Falcons are small to medium sized birds of prey with long pointed wings. Unlike most other raptors, they belong to the Falconidae rather than the Accipitridae. Many are particularly swift flyers. Instead of building their own nests, falcons appropriate old nests of other birds but sometimes they lay their eggs on cliff ledges or in tree hollows.

* Harriers are large, slender hawk-like birds with long tails and long thin legs. Most hunt by gliding and circling low over grasslands and marshes on their long broad wings.

* Hawks are medium-sized birds of prey that usually belong to the genus Accipiter (but see below). They are mainly woodland birds that hunt by sudden dashes from a concealed perch. They usually have long tails.

* Buzzards are raptors with a robust body and broad wings, or, alternatively, any bird of the genus Buteo (also commonly known as Hawks in North America).
