The Amur falcon (Falco amurensis) is a small raptor of the falcon family. It breeds in south-eastern Siberia and Northern China before migrating in large flocks across India and over the Arabian Sea to winter in Southern and East African coasts.

Description

Males are characteristically dark sooty grey above with rufous thighs and vent. In flight, the wing lining is white, contrasting with the dark wing feathers. Adult males of the closely related red-footed falcon have a dark grey wing lining. In Africa, males can be confused with melanistic Gabar goshawks, but the chestnut on the vent is distinctive. Also, there may be some superficial resemblance to the sooty falcon and the grey kestrel, but those two species both have yellow feet and cere. The wings are long as in most falcons (with a span of 63–71 cm) and at rest the wing tip reaches or extends just beyond the tail-tip. [2]

Females can be more difficult to identify as they share a pattern common to many falcons, but are distinctive in having an orange eye-ring, a red cere and reddish orange feet. Juveniles can be confused only with those of the red-footed falcon, but lack the buffy underwing coverts.

Taxonomy

The Amur falcon was long considered a subspecies or morph of the red-footed falcon, but it is nowadays considered a distinct species. Nonetheless, it is the red-footed falcon's closest relative; their relationship to other falcons is more enigmatic. They appear morphologically somewhat intermediate between kestrels and hobbies and DNA sequence data has been unable to further resolve this question, mainly due to lack of comprehensive sampling. [3] [4] [5]

The genus name Falco is Late Latin and derives from falx, falcis, a sickle, referencing the claws of the bird. [6] The species name amurensis is from Amurland in south-eastern Siberia. [7]

Distribution and migration

The Amur falcon breeds in east Asia from the Transbaikalia, Amurland, and northern Mongolian region to parts of North Korea. They migrate in a broad front through India and Sri Lanka, sometimes further east over Thailand and Cambodia and then over the Arabian Sea, sometimes in passage on the Maldives and other islands to reach southern Africa. Birds going over India are thought to be aided by strong winds blowing westward. These winds are strong at an altitude of about 3000m and the birds are thought to fly at a height of above 1000m during migration. [9] The route taken to return to their breeding grounds runs slightly more northward. Because of its tendency to wander long distances over the ocean while migrating, this falcon has been found in locations far outside its normal range, such as in Italy, Sweden, Tristan da Cunha, St. Helena and the United Kingdom. [8] [2]

Behaviour and ecology

Foraging and food

The Amur falcon feeds mainly late in the evening or early in the morning capturing a wide range of insects in the air or on the ground. They capture most of their prey in flight, sometimes by hovering, but will also pick prey by alighting on the ground. [8] The winter diet appears to be almost entirely made up of insects [10] but they take small birds, mammals [11] and amphibians to feed their young in their breeding range. The rains in Africa produce swarms of termites, locusts, ants and beetles that provide ample food. [12] Their migration over the Arabian Sea coincides with the timing of the migration of dragonflies ( Pantala flavescens ) and these are thought to provide food during the most arduous part of their migration route. [13] [14]

Nesting

During migration they stay in open forest or grasslands, roosting colonially on exposed perches or wires. [8] Their breeding habitat is open wooded country with marshes. The breeding season is May to June and several pairs may nest close together. Abandoned nest platforms belonging to birds of prey or corvids and even tree hollows are re-used for nesting. Three or four eggs are laid (at two day intervals). Both parents take turns to incubate and feed the chicks which hatch after about a month. The young birds leave the nest after about a month. [8]

Parasites

The Amur falcon hosts three species of lice, Degeeriella rufa, Colpocephalum subzerafae, and Laembothrion tinnunculi. [15]

Status and conservation

The wide breeding range and large population size of the Amur falcon have led to the species being assessed as being of least concern. The flocking behaviour during migration and the density at which they occur, however, expose them to hunting and other threats. During their migration from their breeding area to the winter quarters, they are plump and are hunted for food in parts of northeastern India as well as in eastern Africa. [1] [16] In 2012, mass trapping and capture of migrating Amur falcons in Nagaland (India) was reported in the media and a successful campaign was begun to prevent their killing. [17] As part of this campaign, three birds were fitted with 5 gm satellite transmitters that allowed them to be tracked during their migration. [18]

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">Falconidae</span> Family of birds

The falcons and caracaras are around 65 species of diurnal birds of prey that make up the family Falconidae. The family likely originated in South America during the Paleocene and is divided into three subfamilies: Herpetotherinae, which includes the laughing falcon and forest falcons; Polyborinae, which includes the spot-winged falconet and the caracaras; and Falconinae, the falcons and kestrels (Falco) and falconets (Microhierax).

<span class="mw-page-title-main">Peregrine falcon</span> Fastest known animal and common 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.

The American kestrel, is the smallest and most common falcon in North America. Formerly called "sparrowhawk", a misnomer as it is a true falcon and is unrelated genetically to the Eurasian sparrowhawk, Accipiter nisus. 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.

The nankeen kestrel, also known as the Australian kestrel, is a raptor native to Australia and New Guinea. It is one of the smallest falcons, and unlike many, does not rely on speed to catch its prey. Instead, it simply perches in an exposed position, but it also has a distinctive technique of hovering over crop and grasslands.

<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">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">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.
