Buteo
''Buteo'' is a genus of medium to fairly large, wide-ranging raptors with a robust body and broad wings. In the Old World, members of this genus are called "buzzards", but "hawk" is used in the New World (Etymology: ''Buteo'' is the Latin name of the common buzzard). As both terms are ambiguous, buteo is sometimes used instead, for example, by the Peregrine Fund. Characteristics Buteos are fairly large birds. Total length can vary from and wingspan can range from . The lightest known species is the roadside hawk, at an average of although the lesser known white-rumped and Ridgway's hawks are similarly small in average wingspan around , and average length around in standard measurements. The largest species in length and wingspan is the upland buzzard, which averages around in length and in wingspan. The upland is rivaled in weight and outsized in foot measurements and bill size by the ferruginous hawk. In both of these largest buteos, adults typically weigh over , and i ...

Common Buzzard
The common buzzard (''Buteo buteo'') is a medium-to-large bird of prey which has a large range. A member of the genus ''Buteo'', it is a member of the family Accipitridae. The species lives in most of Europe and extends its breeding range across much of the Palearctic as far as northwestern China (Tian Shan), far western Siberia and northwestern Mongolia.Ferguson-Lees, J., & Christie, D. A. (2001). ''Raptors of the world''. Houghton Mifflin Harcourt. Over much of its range, it is a year-round resident. However, buzzards from the colder parts of the Northern Hemisphere as well as those that breed in the eastern part of their range typically migrate south for the northern winter, many journeying as far as South Africa.Bildstein, K.

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 within the genus of ''Buteo'' in North America or worldwide. The red-tailed hawk is one of three species colloquially known in the United States as the " chickenhawk", though it rarely preys on standard-sized chickens. The bird is sometimes also referred to as the red-tail for short, when the meaning is clear in context. 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 (from small meadows to the treed fringes of more extensive prairies), coniferous and deciduous forests, agricultur ...

Upland Buzzard
The upland buzzard (''Buteo hemilasius'') is a species of bird of prey in the family Accipitridae. The largest species of the ''Buteo'' genus, this buzzard lives in mountainous grassy and rocky areas in areas of Central Asia, northern South Asia and East Asia from Kazakhstan to Korea.Ferguson-Lees, J., & Christie, D. A. (2001). ''Raptors of the World''. Christopher Helm, London, UK. The upland buzzard is Bird migration, migratory but typically covers a short distance apparently to avoid Snow, snow cover that may hamper prey capture.Bildstein, K. L. & Zalles, J. I. (2005).

Rough-legged Buzzard
The rough-legged buzzard or rough-legged hawk (''Buteo lagopus'') is a medium-large bird of prey. It is found in Arctic and Subarctic regions of North America, Europe, and Russia during the breeding season and migrates south for the winter. It was traditionally also known as the rough-legged falcon in such works as John James Audubon's ''The Birds of America''. Nests are typically located on cliffs, bluffs or in trees. Clutch sizes are variable with food availability, but three to five eggs are usually laid. These hawks hunt over open land, feeding primarily on small mammals. Along with the kestrels, kites, and osprey, this is one of the few birds of prey to hover regularly. Description This fairly large raptorial species is with wingspan ranging from . Individuals can weigh from with females typically being larger and heavier than males. Weights appear to increase from summer to winter in adults, going from an average of in males and from in females. Among the members of t ...

Red-shouldered Hawk
The red-shouldered hawk (''Buteo lineatus'') is a medium-sized buteo. Its breeding range spans eastern North America and along the coast of California and northern to northeastern-central Mexico. It is a permanent resident throughout most of its range, though northern birds do migrate, mostly to central Mexico. The main conservation threat to the widespread species is deforestation. Taxonomy The red-shouldered hawk was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the eagles, hawks and relatives in the genus '' Falco'' and coined the binomial name ''Falco lineatus''. Gmelin based his account on the "barred-breasted buzzard" of John Latham and the "red shouldered falcon" of Thomas Pennant. Latham had described a preserved specimen from North America in the Leverian collection while Pennant's specimen formed part of the collection of Anna Blackburne and had ...

Ferruginous Hawk
The ferruginous hawk, (''Buteo regalis''), is a large bird of prey and belongs to the broad-winged buteo hawks. An old colloquial name is ferrugineous rough-leg, due to its similarity to the closely related rough-legged hawk (''B. lagopus''). The generic name ''buteo'' is Latin for 'buzzard'. The specific epithet ''regalis'' is Latin for 'royal' (from ''rex, regis'', 'king').. The common name 'ferruginous' means 'rust-colored' or 'reddish-brown'. This species is a large, broad-winged hawk of the open, arid grasslands, prairie and shrub steppe country; it is endemic to the interior parts of North America. It is used as a falconry bird in its native ranges. Description This is the largest of the North American ''Buteos'' and is often mistaken for an eagle due to its size, proportions, and behavior. Among all the nearly thirty species of ''Buteo'' in the world, only the upland buzzard (''B. hemilasius'') of Asia averages larger in length and wingspan. The weight of the upland ...

Swainson's Hawk
Swainson's hawk (''Buteo swainsoni'') is a large bird species in the Accipitriformes order. This species was named after William Swainson, a British naturalist. It is colloquially known as the grasshopper hawk or locust hawk, as it is very fond of Acrididae (locusts and grasshoppers) and will voraciously eat these insects whenever they are available. Their breeding habitat is prairie and dry grasslands in western North America. They build a stick nest in a tree or shrub or on a cliff edge. This species is a long-distance migrant, wintering in Argentina; it has been recorded as a vagrant in neighboring Chile, in the island countries of the Dominican Republic, and Trinidad and Tobago, and in Norway. This species or its immediate predecessor is the ancestor of the Galápagos hawk, as demonstrated by recent research. Then later diverged from the mainland birds perhaps 300,000 years ago, a very short time in evolution. Description Swainson's hawk is a raptor and a medium-sized mem ...

Hawk
Hawks are bird of prey, birds of prey of the family Accipitridae. They are 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 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; this group is called buzzards in other parts of the world. Generally, buteos have broad wings and sturdy builds. They are relatively larger-winged, shorter-tailed and fly further distances in open areas than accipiters. Buteos descend or pounce on their prey rather than hunting in a 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 hawks in regions where ''buzzard'' i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roadside Hawk
The roadside hawk (''Rupornis magnirostris'') is a relatively small bird of prey found in the Americas. This vocal species is often the most common raptor in its range. It has many subspecies and is now usually placed in the monotypic genus ''Rupornis'' instead of ''Buteo''. Taxonomy The roadside hawk was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the eagles, hawks and relatives in the genus '' Falco'' and coined the binomial name ''Falco magnirostris''. Gmelin based his description on the "Épervier à gros bec de Cayenne" that had been described and illustrated in 1770 by the French polymath Comte de Buffon in his multi-volume ''Histoire Naturelle des Oiseaux ''. The roadside hawk is now the only species placed in the genus ''Rupornis'' that was introduced in 1844 by the German naturalist Johann Jakob Kaup. The genus name combines the Ancient Greek ''r ...
