Bird of prey
Birds of prey are
birds that hunt for food primarily on the wing, using their keen senses, especially vision. Their talons and beaks tend to be relatively large, powerful and adapted for tearing and/or piercing flesh. The term " raptor" is derived from the Latin word [http://en.wiktionary.org/wiki/rapio#Latin "rapere"] and may refer informally to all birds of prey, or specifically to the diurnalgroup.cite book|author=Brown, Leslie|year=1997|publisher=Chancellor Press|isbn=185152732X|title=Birds of Prey]
The diurnal birds of prey are formally classified into five families:
Accipitridae: hawks, eagles, buzzards, harriers, kites and Old World vultures
Pandionidae: the Osprey(sometimes classified as subfamily Pandioninae of the previous family)
Sagittariidae: the Secretary Bird
Falconidae: falcons and caracaras
Cathartidae: New world vultures including condors.
The observation that otherwise unrelated bird groups may perform similar ecological roles and bear striking morphological similarities to one another is explained largely by the idea of
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.
* 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.
*Ospreys a single species found worldwide, specializes in 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 vetebrate 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.
Buzzardsare 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).
* Harriers are large, slender hawk-like birds with long tails and long thin legs. Most hunt small vertebrates with a combination of keen eyesight and hearing, gliding and circling low over
grasslands and marshes on their long broad wings.
Vultures are carrion-eating raptors of two distinct biological families, each occurring in only the Eastern Hemisphere(Accipitridae) or the Western (Cathartidae). Members of both groups have heads either partly or fully devoid of feathers.
* Falcons are small to medium sized birds of prey with long pointed wings. Unlike most other raptors, they belong to the
Falconidaerather 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. Caracaras are a distinct subgroup of the Falconidae unique to the New World, and most common in the Neotropics- broad wings, naked faces and the appetites of a generalist suggest some level of convergence with either the "Buteo"s or the vulturine birds, or both.
Owlsare variable-sized, typically night-specialized hunting birds. They fly soundlessly and have very acute senses of hearing and low-light vision.
