Hierofalcon
The hierofalcons are four closely related species of falcon which make up the subgenus ''Hierofalco'': * Lanner falcon, ''Falco biarmicus'' * Laggar falcon, ''Falco jugger'' * Saker falcon, ''Falco cherrug'' * Gyrfalcon, ''Falco rusticolus'' The black falcon of Australia is occasionally considered allied to the hierofalcons: indeed it seems fairly close to them (Wink et al. 2004). They represent members of their genus which are similar to species like the peregrine falcon in outward appearance, but usually with more phaeomelanins which impart reddish or brown colors, and generally more strongly patterned plumage reminiscent of hawks. Their undersides usually have a lengthwise pattern of dark blotches, lines or arrowhead marks. They hunt usually in level flight, more like goshawks than peregrines with their dive attack or hobbies with their acrobatic pursuits. Recent DNA sequence data studies have confirmed that the hierofalcons are a monophyletic group—and, incidentally, that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falcon
Falcons () are birds of prey in the genus ''Falco'', which includes about 40 species. Falcons are widely distributed on all continents of the world except Antarctica, though closely related raptors did occur there in the Eocene. Adult falcons have thin, tapered wings, which enable them to fly at high speed and change direction rapidly. Fledgling falcons, in their first year of flying, have longer flight feathers, which make their configuration more like that of a general-purpose bird such as a broad wing. This makes flying easier while learning the exceptional skills required to be effective hunters as adults. The falcons are the largest genus in the Falconinae subfamily of Falconidae, which itself also includes another subfamily comprising caracaras and a few other species. All these birds kill with their beaks, using a tomial "tooth" on the side of their beaks—unlike the hawks, eagles, and other birds of prey in the Accipitridae, which use their feet. The largest fal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prairie Falcon
The prairie falcon (''Falco mexicanus'') is a medium-large sized falcon of western North America. It is about the size of a peregrine falcon or a crow, with an average length of 40 cm (16 in), wingspan of approximately 1 meter (40 in), and average weight of 720 g (1.6 lb). As in all falcons, females are noticeably bigger than males. Though a separate species from the peregrine, the prairie falcon is basically an arid environment adaptation of the early peregrine falcon lineage, able to subsist on less food than the peregrine, and generally lighter in weight than a peregrine of similar wing span. Having evolved in a harsh desert environment with low prey density, the prairie falcon has developed into an aggressive and opportunistic hunter of a wide range of both mammal and bird prey. It will regularly take prey from the size of sparrows to approximately its own weight, and occasionally much larger. It is the only larger falcon native only to North America. ...

Saker Falcon
The saker falcon (''Falco cherrug'') is a large species of falcon. This species breeds from central Europe eastwards across the Palearctic to Manchuria. It is mainly migratory except in the southernmost parts of its range, wintering in Ethiopia, the Arabian peninsula, northern Pakistan and western China. The saker falcon is the national bird of Hungary, the United Arab Emirates, and Mongolia. Taxonomy and systematics This species belongs to the close-knit hierofalcon complex. In this group, there is ample evidence for rampant hybridization and incomplete lineage sorting which confounds analyses of DNA sequence data to a massive extent; molecular studies with small sample sizes can simply not be expected to yield reliable conclusions in the entire hierofalcon group. The radiation of the entire living diversity of hierofalcons seems to have taken place in the Eemian interglacial at the start of the Late Pleistocene, a mere 130,000–115,000 years ago; the saker falcon represents ...

Peregrine Falcon
The peregrine falcon (''Falco peregrinus''), also known as the peregrine, and historically as the duck hawk in North America, is a Cosmopolitan distribution, cosmopolitan bird of prey (Bird of prey, raptor) in the family (biology), family Falconidae. A large, Corvus (genus), crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The peregrine is renowned for its speed, reaching over during its characteristic hunting stoop (high-speed dive), making it the fastest bird in the world, as well as the Fastest animals, fastest member of the animal kingdom. According to a ''National Geographic (U.S. TV channel), National Geographic'' TV program, the highest measured speed of a peregrine falcon is . As is typical for avivore, bird-eating raptors, peregrine falcons are Sexual dimorphism, sexually dimorphic, with females being considerably larger than males. The peregrine's breeding range includes land regions from the Arctic tundra to the tropics. It can b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Falco Biarmicus
The lanner falcon (''Falco biarmicus'') is a medium-sized bird of prey that breeds in Africa, southeast Europe and just into Asia. It prefers open habitat and is mainly resident, but some birds disperse more widely after the breeding season. A large falcon, it preys on birds and bats. Taxonomy and etymology The lanner falcon was described by the Dutch zoologist Coenraad Jacob Temminck in 1825 under the current binomial name ''Falco biarmicus''. The type locality is Caffraria and the Cape of Good Hope. ''Falco'' is Late Latin for a "falcon", from ''falx'', ''falcis'' "sickle". The Swedish naturalist Carl Linnaeus had used the specific epithet ''biarmicus'' for the bearded reedling and Temminck clearly believed that the word meant "bearded" but it is likely that Linnaeus was using the Latinized form for Bjarmaland, a district in northern Russia. The English word "lanner" is believed to come from the Old French ''lanier'' meaning "cowardly". The first recorded use of the word in E ...

Falco Jugger
The laggar falcon (''Falco jugger''), also known as the lugger falcon or jugger (from Hindi जग्गर — jaggar, “falcon”) is a mid-sized bird of prey which occurs in the Indian subcontinent from extreme southeastern Iran, southeastern Afghanistan, Pakistan, through India, Nepal, Bhutan, Bangladesh and northwestern Myanmar. It resembles the lanner falcon but is darker overall, and has blackish "trousers" (tibiotarsus feathers). Fledglings have an almost entirely dark underside, and first-year subadult birds still retain much dark on the belly. This species belongs to a close-knit complex of falcons known as hierofalcons. In this group, there is ample evidence for rampant hybridization and incomplete lineage sorting which confounds analyses of DNA sequence data to a massive extent; molecular studies with small sample sizes can simply not be expected to yield reliable conclusions in the entire hierofalcon group.

Falco Rusticolus
The gyrfalcon ( or ) (), the largest of the falcon species, is a bird of prey. The abbreviation gyr is also used. It breeds on Arctic coasts and tundra, and the islands of northern North America and the Eurosiberian region. It is mainly a resident there also, but some gyrfalcons disperse more widely after the breeding season, or in winter. Individual vagrancy can take birds for long distances. Its plumage varies with location, with birds being coloured from all-white to dark brown. These colour variations are called morphs. Like other falcons, it shows sexual dimorphism, with the female much larger than the male. For centuries, the gyrfalcon has been valued as a hunting bird. Typical prey includes the ptarmigan and waterfowl, which it may take in flight; it also takes fish and mammals. Taxonomy and etymology The gyrfalcon was formally described by Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under its current binomial name ''Falco ...
