Hawk
Hawks are birds of prey of the family Accipitridae. They are very widely distributed and are found on all continents, except Antarctica. The subfamily Accipitrinae includes goshawks, sparrowhawks, sharp-shinned hawks, and others. This subfamily are mainly woodland birds with short broad wings, long tails, and high visual acuity. They hunt by dashing suddenly from a concealed perch. In America, members of the ''Buteo'' group are also called hawks, though birds of this group are called buzzards in other parts of the world. Generally, buteos have broad wings and sturdy builds. They are relatively larger-winged and shorter-tailed than accipiters, and fly further distances in open areas. Buteos descend or pounce on their prey rather than engaging in fast, horizontal pursuit. The terms ''accipitrine hawk'' and ''buteonine hawk'' are used to distinguish between the types in regions where ''hawk'' applies to both. The term ''"true hawk"'' is sometimes used for the accipitrine ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-tailed Hawk
The red-tailed hawk (''Buteo jamaicensis'') is a bird of prey that breeds throughout most of North America, from the interior of Alaska and northern Canada to as far south as Panama and the West Indies. It is one of the most common members of the genus ''Buteo''. The red-tailed hawk is one of three species colloquially known in the United States as the "Chickenhawk (bird), chickenhawk", though it rarely preys on standard-sized chickens. Red-tailed hawks can acclimate to all the biomes within their range, occurring on the edges of non-ideal habitats such as dense forests and sandy deserts.Preston, C. R. (2000). ''Red-tailed Hawk''. Stackpole Books. The red-tailed hawk occupies a wide range of habitats and altitudes, including deserts, grasslands, coniferous and deciduous forests, Agricultural land, agricultural fields, and Urbanization, urban areas. Its latitudinal limits fall around the tree line in the subarctic and it is absent from the high Arctic. It favors varied habitats ...

Eurasian Goshawk
The Eurasian goshawk (; ''Astur gentilis'', formerly ''Accipiter gentilis'') is a species of medium-large bird of prey in the Family (biology), family Accipitridae, a family which also includes other extant diurnal raptors, such as eagles, buzzards and harrier (bird), harriers. It was formerly placed in the genus ''Accipiter''. It is a widespread species that inhabits many of the temperate parts of Eurasia. Except in a small portion of southern Asia, it is the only species of "goshawk" in its range and it is thus often referred to, both officially and unofficially, as simply goshawk. It is mainly resident bird, resident, but birds from colder regions bird migration, migrate south for the winter. As of 2023, goshawks found in North America are no longer considered be conspecific, but are now designated as the American goshawk (''Astur atricapillus''). Taxonomy The Eurasian goshawk was Species description, formally described in 1758 by the Swedish naturalist Carl Linnaeus in the 10 ...

Megatriorchis
Doria's hawk or Doria's goshawk (''Megatriorchis doriae'') is a raptor in the family Accipitridae that lives in the Indonesia and Papua New Guinea areas. It is the only species placed in the genus ''Megatriorchis''. Within the family, it is relatively large in size with up to 69 cm long with the female being larger in size than the male. Field identification It is greyish-brown with a black-barred crown and upperparts, whitish underparts, a black streak behind the eye, dark brown irises, a blackish bill and greenish-yellow legs. The sexes are similar. The female is slightly larger than the male. The juvenile is a little bit lighter in color that resembles a reddish brown shade. Doria’s hawk is a grayish-brown bird with a streaking pattern on its chest. The bird has the characteristics of a large, skinny hawk with a hefty bill, tiny head, strong legs, a modest crest, and wings that have a smooth, curved surface. It is not considered a typical hawk.

Micronisus
The gabar goshawk (''Micronisus gabar'') is a small species of African and Arabian bird of prey in the family Accipitridae. Description The gabar goshawk is polymorphic and occurs in two distinct forms which fluctuate in relative abundance across the geographic range of the species. The more frequent, paler form has mostly grey upperparts with a conspicuous, white rump and white and grey barring on the chest, thighs and underwings, and a dark grey, barred tail. In contrast, the less frequent form, which accounts on average for approximately 25 percent of the overall population, is almost completely black. In both forms of adult the eyes are dark, and the legs are long and the cere is red. The cere and the legs are yellow in immatures and the plumage is generally browner, with the pale birds having untidier barring on the chest than the adult. The females are significantly larger than the males, the male's weigh 90 – 173g and the females 167 – 240g The body length is 28–36 ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Accipiter
''Accipiter'' () is a genus of birds of prey in the family Accipitridae. Some species are called sparrowhawks, but there are many sparrowhawks in other genera such as '' Tachyspiza''. These birds are slender with short, broad, rounded wings and a long tail which helps them maneuver in flight. They have long legs and long, sharp talons used to kill their prey, and a sharp, hooked bill used in feeding. Females tend to be larger than males. They often ambush their prey, mainly small birds and mammals, capturing them after a short chase. The typical flight pattern is a series of flaps followed by a short glide. They are commonly found in wooded or shrubby areas. The genus ''Accipiter'' was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The type species is the Eurasian sparrowhawk (''Accipiter nisus''). The name is Latin for "hawk", from ''accipere'', "to grasp".

Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Woodland
A woodland () is, in the broad sense, land covered with woody plants (trees and shrubs), or in a narrow sense, synonymous with wood (or in the U.S., the '' plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American and Australian English explained below). Some savannas may also be woodlands, such as ''savanna woodland'', where trees and shrubs form a light canopy. Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana ha ...

Falconry
Falconry is the hunting of wild animals in their natural state and habitat by means of a trained bird of prey. Small animals are hunted; squirrels and rabbits often fall prey to these birds. Two traditional terms are used to describe a person involved in falconry: a "falconer" flies a falcon; an "austringer" (Old French origin) keeps Eurasian goshawks and uses hawk, accipiters for hunting. In modern falconry, the red-tailed hawk (''Buteo jamaicensis''), Harris's hawk (''Parabuteo unicinctus''), and the peregrine falcon (''Falco perigrinus'') are some of the more commonly used birds of prey. The practice of hunting with a conditioned falconry bird is also called "hawking" or "gamehawking", although the words wikt:hawking, hawking and peddler, hawker have become used so much to refer to petty traveling traders, that the terms "falconer" and "falconry" now apply to most use of trained birds of prey to catch game. However, many contemporary practitioners still use these words in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Duck Hawk
The peregrine falcon (''Falco peregrinus''), also known simply as the peregrine, is a Cosmopolitan distribution, cosmopolitan bird of prey (raptor) in the family (biology), family Falconidae renowned for its speed. A large, Corvus (genus), crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. As is typical for avivore, bird-eating (avivore) raptors, peregrine falcons are Sexual dimorphism, sexually dimorphic, with females being considerably larger than males. Historically, it has also been known as "black-cheeked falcon" in Australia, and "duck hawk" in North America. The breeding range includes land regions from the Arctic tundra to the tropics. It can be found nearly everywhere on Earth, except extreme polar regions, very high mountains, and most tropical rainforests; the only major ice-free landmass from which it is entirely absent is New Zealand. This makes it the world's most widespread Raptor (bird), raptor and one of the most widely found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
