The saker falcon (Falco cherrug Gray, 1834) 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. [2]

The saker falcon is the second fastest bird in level flight after the white-throated needletail swift, capable of reaching 150 km/h (93 mph). It is also the third fastest animal in the world overall after the peregrine falcon and the golden eagle, with all three species capable of executing high speed dives known as "stooping", approaching 300 km/h (190 mph). [3] The saker falcon is the national bird of Hungary, the United Arab Emirates, and Mongolia. It is called by Arabs "Hur" ie Free-bird where it is used in falconry since very ancient times in the Arabic peninsula.Saker Falcons are the national bird of the United Arab Emirates, Saudi Arabia, Qatar, Oman and Yemen and have been integral to Arab heritage and culture for over 9,000 years. They are the national emblem of many Arabic countries. [4] [5]

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 a lineage that expanded out of northeastern Africa into the interior of southeastern Europe and Asia, by way of the eastern Mediterranean region. [6] [7] [8] [9]

The Saker Falcon has four officially recognized subspecies in the international ornithology according to IOC World Bird List:


- F.c. cherrug - the nominate subspecies distributed from Central Europe to Central Asia;

- F.c. coatsi - a subspecies of the desert regions of West and South Kazakhstan and Uzbekistan;

- F.c. milvipes - the typical subspecies widespread in most parts of Central Asia;

- F.c. hendersoni - the subspecies of high elevations of Tibet and the Qinghai Plateau.


Some saker falcons at the northeast edge of the range in the Altai Mountains are slightly larger, and darker and more heavily spotted on the underparts. These, known as the Altai falcon , have been treated in the past either as a distinct species "Falco altaicus" or as a hybrid between saker falcon and gyrfalcon. However, modern opinion (e.g. ( Orta 1994 )) treats them as a form of saker falcons, and now new research in population genetics and ecology supports that view. [10] According to a a recent study, Altai falcons are genetically intermingled with the broader Asian Saker population and do not constitute a distinct cluster, indicating that they are only colour morphs, and do not represent a separate taxonomic entity.

In captivity, lanners and sakers can interbreed, and gyrfalcon-saker hybrids are also available (see bird flu experiment described in "Ecology and status"). The specific name, cherrug, comes from the Sindhi name charg for a female saker. [11] The common name saker comes from the (Arabic : صقر, romanized: Ṣaqr) meaning "falcon". [12] [13]

Description

The saker falcon is a large hierofalcon, larger than the lanner falcon and almost as large as gyrfalcon at 45–57 cm (18–22 in) length with a wingspan of 97–126 cm (38–50 in). Males weigh between 730–990 g (26–35 oz) and females 970–1,300 g (34–46 oz). It resembles a larger but browner Prairie Falcon. It is larger and more heavily built than the related Lanner Falcon. [10]

Saker falcons tend to have variable plumage. Males and females are similar, except in size, as are young birds, although these tend to be darker and more heavily streaked. The call is a sharp kiy-ee or a repeated kyak-kyak-kyak. [10]

Ecology

The saker falcon is a raptor of open grasslands preferably with some trees or cliffs. It often hunts by horizontal pursuit, rather than the peregrine's stoop from a height, and feeds mainly on rodents and birds. In Europe, ground squirrels and feral pigeons are the most common prey items. This species usually builds no nest of own, but lays its 3–6 eggs in an old stick nest in a tree which was previously used by other birds such as storks, ravens or buzzards. It also often nests on cliffs.

Saker nests support a species-rich assemblage of commensal insects. [14]

Status and conservation

BirdLife International categorises this bird as endangered, due to a rapid population decline, particularly on the central Asian breeding grounds. Ever since the collapse of the Soviet Union, the United Arab Emirates have been the main destination for thousands of falcons caught and sold illegally for hefty sums at the black market. Kazakhstan is estimated to lose up to 1,000 saker falcons per year. [15]

The species also faces pressure from habitat loss and destruction. The population was estimated to be between 7,200 and 8,800 mature individuals in 2004. However, sakers live at low densities across large ranges in remote regions, making distribution status difficult to assess. A climatic niche modelling study pinpointed certain remote areas for targeted population surveys. [16] In the United States, Canada and Europe there are several captive breeding projects. The most dramatic decline of the saker falcon in Asia has been in Kazakhstan and Uzbekistan. In contrast, a strongly protected and relatively abundant population persists in Hungary.

Saker falcons are known to be very susceptible to avian influenza, individuals having been found infected with highly pathogenic H5N1 (in Saudi Arabia) and H7N7 (in Italy) strains. Therefore, an experiment was done with hybrid gyr-saker falcons, which found that five falcons vaccinated with a commercial H5N2 influenza vaccine survived infection with a highly pathogenic H5N1 strain, whereas five unvaccinated falcons died. This means that sakers could be protected from bird flu by vaccination, at least in captivity. [17]

In culture

A Hungarian mythological bird, the Turul, was probably a saker falcon (kerecsensólyom), and the saker falcon is the national bird of Hungary. [18] [19] In 2012, the saker falcon was selected as the national bird of Mongolia. [20]

Use in falconry

The saker falcon has been used in falconry for thousands of years, and like its very close relative, the gyrfalcon, is a highly regarded in it. Swift and powerful, it is effective against medium-sized to large-sized game bird species. [21] Saker falcons can reach speeds of 120 to 150 km/h and suddenly swoop down on their prey. [22] The saker falcon and peregrine falcon can be hybridised to provide falcons used in the control of larger birds considered pests. [23] [24]

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">Falconry</span> Hunting with a trained bird of prey

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" flies a hawk or an eagle. In modern falconry, the red-tailed hawk, Harris's hawk, and the peregrine falcon 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 hawking and 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. Many contemporary practitioners still use these words in their original meaning, however.

<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.

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.

It has a roughly two-to-one range in size over subspecies and sex, varying in size from about the weight of a blue jay to a mourning dove. It also ranges to South America and is a well-established species that has evolved into 17 subspecies adapted to different environments and habitats throughout the Americas. It exhibits sexual dimorphism in size and plumage, although both sexes have a rufous back with noticeable barring. Its plumage is colorful and attractive, and juveniles are similar in plumage to adults.

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

The red-necked falcon is a bird of prey in the falcon family with two disjunct populations, one in India and the other in Africa. This medium-sized falcon has bluish grey wings and upper body, a chestnut red cap with short chin straps passing through the eye. The primary feathers of the wing are black and a single black band at the tip of the tail are distinctive. The Indian subspecies Falco chicquera chicquera also known as the red-headed merlin or red-headed falcon is found mainly in the open plains of the India Subcontinent although it is thought to have occurred further west in southeastern Iran. The subspecies Falco chicquera ruficollis found in sub-Saharan Africa is sometimes treated as a full species, the rufous-necked falcon, on the basis of its well-separated geographic range and distinctive pattern. It appears very similar to the Indian form but has dark barring on the upperparts, a rufous breast band, and black moustachial and eye stripes. As in most falcons, the females are larger and falconers in India called the female turumti and the male as chatwa. They hunt in pairs mostly at dawn and dusk, capturing small birds, bats and squirrels.

<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">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.

Hacking is a training method that helps young birds of prey reach their hunting potential by giving them exercise and experience. This technique is used to prepare the falcon to become an independent hunter. The sequence of the procedure includes captivity, releasing, flight, and either the falcon will be recaptured for falconry or released into the wild. This has also been adapted to other raptor species to preserve the population. Generally, falconers agree that hacked falcons are better and more preferred in the field. Hacking is beneficial, not only for the falconers, but for the bird itself and the species; however, there are some criticism and restrictions that come along with this method.

The Altai falcon has been identified as a color morph of the Central Asian saker falcon, as per the latest genetic research. Previously, it was variously classified as a morph, a subspecies, and even separate species. It used to have a high reputation among Central Asian falconers.

<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.
