Hawk - Accipitridae

And hawks, and one of the great families of the order Charadriiformes (diurnal birds of prey), is a small family of large birds with a highly variable morphology bills conductivity on the basis of the diet. RSS on a variety of prey from insects and mammals of medium size, with the number of feeding on carrion and feeding on berries. Hawks and worldwide distribution, found in every continent of the world (except Antarctica), and a number of groups of oceanic islands. Some migratory species.

Accipitridae found in most terrestrial environments, including the tundra, and alpine meadows, pastures and deserts, tropical forests and marine and coastal, forest, agricultural, suburban and even in some urban areas. They are also present in most mountainous regions, coastal areas to sea level to mountain tops. Found the greatest number of species in the Accipitridae forest and bush, while the less productive habitats such as desert steppe and tundra can support is usually only one or two species. Many types of birds of prey rely on trees for nesting, roosting, perching and hunting. Therefore, habitat trees can usually withstand a lot of these types of Raptor without trees. 
Accipitridae expel much of the winter between education and habitats. People who migrate south in winter, the winter home of choice is usually a structure similar to breeding habitat. For example, species that breed in forests are generally open habitat selection of winter in tropical forests are open to some extent.

Falcon is one of three families in the order Falconiformes, which also includes falcons (Falconidae) and secretary birds (hawks). Evolutionary relationships between these families is unclear. Have long recognized the members of the taxonomic group hawks, despite previous classifications and collected in many cases, other birds of prey in this group, including eagles and owls of the New World. Although similar patterns of predators and certain characteristics of matter, are not closely related to any of these groups Accipitridae.
There are two types of hawks within the subfamilies, and Accipitrinae Pandioninae. The latter type includes a single species, Pandion haliaetus (Ospreys). And widely discussed in the position of the hawks Ospreys in the family. In fact, the class of most single-species classifications Ospreys in a separate family (hawks). And includes the remaining species Accipitrinae 232 Accipitridae species, including hawks, kites, harriers, eagles, eagles and real fish and birds of prey in the ancient world.

Diurnal birds of prey eagles with wings large, hooked beaks, legs and feet strong and sharp claws. All the Accipitridae Kir, which is the waxy membrane that are often brightly colored and cover the base jaws higher. Their large eyes are shaded by the ridge above the pilgrims in most species, which made his face seem fierce. Scale adult eagles from 50 to 300 cm and the total body length ranging from 25 to 150 cm. The public body Accipitridae wide 80 to 12.5 g kg.

You can see a variety of body shapes and Accipitridae blades. For example, the tail may be square, rounded, wedge-shaped or even forked. Accipitridae reflects the physical properties to adapt to their environment, and how to look for food and prey. For example, species living in forests are generally short wings and long tail, a combination that allows them the ability to maneuver. Species that live in open environments and chased by the general rise in long, broad wings and short tail, allowing them to easily climb over long distances. Many species also high, "fingers", which is the first outer feathers for a time to reduce the drag on the wings of birds has increased slowly without stalling.
Most Accipitridae, unilateral, and much of his life. Although polygamy and polyandry occur regularly in some species, these species are exceptional. Most types of hawks and containment, and protection of land around the nest. The size of the territory of the pair and their ability to defend them against other dogs depends on the species and habitats. Species generally open country, drive the interlopers out more of the species that live in forests, perhaps because foreigners are more difficult to detect in forest habitats. Colonial breeding occurs in some species with an abundance of sites of high prey and suitable nest sites. North American examples of this species include Northern Harrier, and snail kites.
