Falco hierofalco (see text)

The hierofalcons are four closely related species of falcon which make up the subgenus Hierofalco:

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 Accipiters 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 hybridization runs rampant in the present species complex. Initial results of mtDNA cytochrome b sequence analyses that suggested they are basal among all living falcons were in error, due to a numt (Wink & Sauer-Gürth 2000). The biogeographically entirely distinct prairie falcon was sometimes placed with the hierofalcons due to its similar coloration; it is now considered not to belong in this subgenus, the similarities being the result of convergent evolution in adaptation to similar habitat.

The hierofalcon lineage as such seems of Late Pliocene origin, maybe as old as the "typical" kestrels (Gelasian, some 2.5–2 million years ago [1] ), maybe somewhat older, though little is known about their fossil history. It seems to have originated in Africa or adjacent regions but apparently became nearly extinct in the past: the present hierofalcon diversity is of rather recent origin, presumably not older than the Eemian interglacial (about 130,000–115,000 years ago) at the start of the Late Pleistocene; only one of the hierofalcon species that presumably diverged between the Pliocene and the Middle Pleistocene has left any living descendants. The lanner falcon appears to be the most phylogenetically ancient species (mainly judging from biogeography); the others diverged—apparently out of a population isolated in northeastern Africa some time during the Riss glaciation 200,000 to 130,000 years ago—in a brief and rapid bout of evolution. DNA sequence data analyses in this group suffers from the extensive hybridization and incomplete lineage sorting confounding the data, and studies with small sample sizes can by no means be considered reliable. Sometimes, all hierofalcons are lumped into one species, Falco hierofalco. [2]

Possible examples of such extinct hierofalcon lineages include Falco bakalovi occurring from the Early Pliocene of Bulgaria to Early Pleistocene of Spain and the Czech Republic [3] and Falco antiquus known from the Middle Pleistocene of Noailles (France) and possibly Hór-völgy (Hungary). [4]

Their name may mean "sacred falcon" (Greek ἱερος = "sacred") or "hawk-falcon" (Greek ἱεραξ = "hawk", but with a Greek grammatical error: the correct combining form of ἱεραξ is "hieraco-").

  3. Similar to the saker falcon (Mlíkovský 2002), but a relationship e.g. with the peregrine falcon cannot be dismissed. Due to the large time interval, it might be more than one species.
  4. Very similar to the saker falcon and classified as a paleosubspecies of that species by Mlíkovský (2002). Not too likely due to the probably more recent origin of the Saker (Nittinger et al. 2005).

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.

<span class="mw-page-title-main">Peregrine falcon</span> Widely distributed bird of prey

The peregrine falcon, also known simply as the peregrine, and historically as the duck hawk in North America, is a cosmopolitan bird of prey (raptor) in the family Falconidae. A large, crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The peregrine is renowned for its speed. It can reach over 320 km/h (200 mph) during its characteristic hunting stoop, making it the fastest member of the animal kingdom. According to a National Geographic TV program, the highest measured speed of a peregrine falcon is 389 km/h (242 mph). As is typical for bird-eating (avivore) raptors, peregrine falcons are sexually dimorphic, with females being considerably larger than males.

<span class="mw-page-title-main">Merlin (bird)</span> Species of bird

The merlin is a small species of falcon from the Northern Hemisphere, with numerous subspecies throughout North America and Eurasia. A bird of prey once known colloquially as a pigeon hawk in North America, the merlin breeds in the northern Holarctic; some migrate to subtropical and northern tropical regions in winter. Males typically have wingspans of 53–58 centimetres (21–23 in), with females being slightly larger. They are swift fliers and skilled hunters which specialize in preying on small birds in the size range of sparrows to quail. The merlin has for centuries been well regarded as a falconry bird. In recent decades merlin populations in North America have been significantly increasing, with some merlins becoming so well adapted to city life that they forgo migration.

<span class="mw-page-title-main">Hobby (bird)</span> Subgenus of birds

A hobby is a fairly small, very swift falcon with long, narrow wings. There are four birds called "hobby", and some others which, although termed "falcon", are very similar. All specialise in being superb aerialists. Although they take prey on the ground if the opportunity presents itself, most prey is caught on the wing; insects are often caught by hawking, and many different birds are caught in flight, where even the quick maneuvering swifts and swallows cannot escape a hobby.

<span class="mw-page-title-main">Eurasian hobby</span> Species of bird

The Eurasian hobby or just hobby, is a small, slim falcon. It belongs to a rather close-knit group of similar falcons often considered a subgenus Hypotriorchis.

<span class="mw-page-title-main">Eleonora's falcon</span> Species of bird

Eleonora's falcon is a medium-sized falcon. It belongs to the hobby group, a rather close-knit number of similar falcons often considered a subgenus Hypotriorchis. The sooty falcon is sometimes considered its closest relative, but while they certainly belong to the same lineage, they do not seem to be close sister species. The English name and the species name eleonorae commemorate Eleanor of Arborea, Queen or Lady-Judge and national heroine of Sardinia, who in 1392, under the jurisdiction conferred by the Carta de Logu, became the first ruler in history to grant protection to hawk and falcon nests against illegal hunters. The genus name falco is from Late Latin falx, falcis, a sickle, referring to the claws of the bird.

<span class="mw-page-title-main">Lanner falcon</span> Bird of prey

The lanner falcon 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. Most likely either the lanner or peregrine falcon was the sacred species of falcon to the ancient Egyptians, and some ancient Egyptian deities, like Ra and Horus, were often represented as a man with the head of a lanner falcon.

<span class="mw-page-title-main">Barbary falcon</span> Subspecies of bird

The Barbary falcon is a medium-sized falcon about the size of a crow. This bird of prey is mainly resident. It ranges from the Canary Islands eastwards across some parts of North Africa, the Middle East and Central Asia.

<span class="mw-page-title-main">Saker falcon</span> Species of bird

The saker falcon is a large falcon species. It breeds from Central Europe eastwards across the Palearctic to Manchuria. It is a partial migrant, which means that some part of the population is migratory, some part is not. In Europe, for example, a part of the juveniles are migrating, while adults are mostly resident. The European and West Asian migratory sakers spend the winter in the Sahel region. On migration, they cross the Middle East, the Arabian peninsula, and Pakistan, where they are exposed to illegal trapping. The migratory birds to the east from Altai Mountains spend the winter in the Qinghai-Tibet Plateau.

<span class="mw-page-title-main">Sooty falcon</span> Species of bird

The sooty falcon is a medium-sized falcon breeding from northeastern Africa to the southern Persian Gulf region. The word sooty means to be covered in soot (ash), and is used to describe the color of the Sooty Falcon. Hence, the falcon gets its name from its color, the color of soot.

<span class="mw-page-title-main">Prairie falcon</span> Species of bird

The prairie falcon 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 divergence 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. It is resident from southern Canada, through western United States, and into northern Mexico. The prairie falcon is popular as a falconry bird, where with proper training it is regarded as being as effective as the more well known peregrine falcon.

<span class="mw-page-title-main">Aplomado falcon</span> Species of bird

The aplomado falcon is a medium-sized falcon of the Americas. The species' largest continuous range is in South America, but not in the deep interior Amazon Basin. It was long known as Falco fusco-coerulescens or Falco fuscocaerulescens, but these names are now believed to refer to the bat falcon. Its resemblance in shape to the hobbies accounts for its old name orange-chested hobby. Aplomado is an unusual Spanish word for "lead-colored", referring to the blue-grey areas of the plumage – an approximate English translation would be "plumbeous falcon". Spanish names for the species include halcón aplomado and halcón fajado ; in Brazil it is known as falcão-de-coleira.

<span class="mw-page-title-main">Gyrfalcon</span> Species of bird

The gyrfalcon, 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.
