Bird of prey

at Combe Martin Wildlife and Dinosaur Park, North Devon, England]]

A **bird of prey** (also called **raptor**) is a bird that mainly uses its claws (called *talons*) to seize prey. They have strong sharp, hooked beaks and claws and have sharp eyesight. 

They are not classified into one natural family or group. The behaviour evolved many times in different groups. This is an illustration of convergent evolution.

## Classification by ancestry 
### Daytime birds 
Those bird of prey that are active during the day (diurnal) are classified into five families in two orders. The orders are the Falconiformes and Accipitriformes.
 
* Accipitridae: hawks, eagles, buzzards, harriers, kites and Old World vultures
* Pandionidae: the osprey 
* Sagittariidae: secretary-bird
* Falconidae: falcons, caracaras and forest falcons

### Nighttime birds 
Nocturnal birds of prey – the owls – are classified separately, as members of two families of the order Strigiformes.

## Common names 
* **Eagles** are large birds with long, broad wings and massive feet. Booted eagles have feathered legs and build large stick nests.
***Ospreys** are one species found worldwide. They specialize in catching fish. They also build large stick nests.
* **Kites** have long wings and weak legs. They spend much of their time soaring. They will take live vertebrates, but mostly feed on insects and carrion.
* **Hawks** are medium to large-sized birds of prey that usually belong to the genus *Accipiter*. They are mainly woodland birds that hunt by sudden dashes from a concealed perch. They usually have long tails for tight steering.
* **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).
* **Harriers** are large, slender hawk-like birds with long tails and long thin legs. They hunt small vertebrates by sight, gliding and circling low over grasslands and marshes on their long broad wings.
***Vultures** are carrion-eating raptors of two different families. Members of both groups have heads either partly or fully devoid of feathers. The vultures are also regarded as birds of prey, although they may not be closely related to the other groups. The Eastern vultures and the western New World vultures are two groups which have evolved separately. Their similarities are due to convergent evolution.
**The Accipitridae only occurs in the Eastern Hemisphere; and 
**The Cathartidae only occurs in the Western Hemisphere. 
* **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. Kestrels are the smallest birds in the group. Caracaras are a subgroup of the Falconidae unique to the New World, and most common in the tropics. 
* **Owls** are variable-sized nocturnal hunting birds.  They fly soundlessly and have very acute senses of hearing and sight.
**Strigidae (typical owls)
**Tytonidae (barn and bay owls)
