The Seychelles kestrel (Falco araeus) is a small bird of prey belonging to the genus Falco in the falcon family, Falconidae. It is endemic to the Seychelles Islands where it is the only breeding bird of prey. It is known in Seychellois Creole as the katiti after its loud, shrill call.

Description

It is the smallest of the kestrels, 18–23 cm long with a wingspan of 40–45 cm. The wings are fairly short and rounded. The adult male's upperparts are reddish brown with black spots while the underparts are unspotted and buff. The head and rump are dark blue-grey. The tail is blue-grey with black bars. The bill is dark and the feet and cere are yellow. Females are similar to the males in appearance but are a little larger and paler. Immature birds have a brown, streaked head, spots on the breast and a buff tip to the tail.

Ecology

It can be seen in forest, scrub and farmland and around rock faces and houses. It rarely hovers, instead feeding by sitting on an exposed perch and waiting for prey to pass, then swooping down to catch it. Lizards, particularly green day geckos ( Phelsuma ) and skinks ( Mabuya ), make up 92% of its diet and it will also take small birds, frogs, rats and insects.

The breeding territory covers just 40 hectares, the smallest of any bird of prey. Breeding occurs from August to October. The nest site is on a cliff, tree or building. It is a simple scrape with no nest material used. Two or three eggs are laid; they are white with brown markings and are incubated for 28–31 days. The young birds fledge after 35–42 days and then remain with their parents for another 14 weeks.

Conservation

The species has a population of about 800 birds and is classified as vulnerable. Lowland nests have a high failure rate of about 70-80%. It probably bred throughout the granitic central Seychelles in the past but is currently known to breed only on Mahé, Silhouette, North Island, Praslin and some small adjacent islands. It was reintroduced to Praslin in 1977.

Threats are thought to include habitat loss due to logging, housing development and fires as well as predation and competition by introduced species. Rats, cats and barn owls have reduced the lizard population on which the kestrels depend and they may take eggs and chicks. Barn owls and common mynas have occupied many suitable nest sites.

Persecution by humans is now rare. In the past, kestrels were killed because they were thought to take chickens and because they were considered to be an omen of death.

Common kestrel Species of bird

The common kestrel is a bird of prey species belonging to the kestrel group of the falcon family Falconidae. It is also known as the European kestrel, Eurasian kestrel, or Old World kestrel. In Britain, where no other kestrel species commonly occurs, it is generally just called "kestrel".

Merlin (bird) 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 who 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.

Pallid harrier Species of bird

The pale or pallid harrier is a migratory bird of prey of the harrier subfamily. The scientific name is derived from the Ancient Greek. Circus is from kirkos, referring to a bird of prey named for its circling flight, probably the hen harrier and macrourus is "long-tailed", from makros, "long" and -ouros "-tailed".

Rough-legged buzzard Species of bird

The rough-legged buzzard or rough-legged hawk 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.

Lesser kestrel Species of bird

The lesser kestrel is a small falcon. This species breeds from the Mediterranean across Afghanistan and Central Asia, to China and Mongolia. It is a summer migrant, wintering in Africa and Pakistan and sometimes even to India and Iraq. It is rare north of its breeding range, and declining in its European range. The genus name derives from Late Latin falx, falcis, a sickle, referencing the claws of the bird, and the species name commemorates the German naturalist Johann Friedrich Naumann.

Red-footed falcon Species of bird

The red-footed falcon, formerly the western red-footed falcon, is a bird of prey. It belongs to the family Falconidae, the falcons. This bird is found in eastern Europe and Asia although its numbers are dwindling rapidly due to habitat loss and hunting. It is migratory, wintering in Africa. It is a regular wanderer to western Europe, and in August 2004 a red-footed falcon was found in North America for the first time on the island of Martha's Vineyard, Massachusetts.

American kestrel North American falcon species

The American kestrel, also called the sparrow hawk, is the smallest and most common falcon in North America. 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.

Nankeen kestrel Species of bird

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.

Indian Ocean kestrels Group of birds

Isolated on various islands around the Indian Ocean, kestrel populations evolved into different species, like Darwin's finches. Behaviour remains similar to other small species of Falco except on (originally) forested Mauritius where kestrels hunt arboreally more like hawks. Due to the scarcity of mammals on oceanic islands, several species have adopted a diet containing many Phelsuma and other geckos. The species can be distinguished by coloration, but all except the banded kestrel share rich brown wings with black spotting. Sexes are alike in color except in the spotted kestrel, where differences are minor. As usual in birds of prey, females are larger than males; considerably so in some of these species as this assists resource partitioning.

Fox kestrel Species of bird

The fox kestrel is a bird of prey belonging to the falcon family Falconidae. It is found in arid, open country in the northern part of Sub-Saharan Africa.

Seychelles black parrot Species of bird

The Seychelles black parrot, Praslin parrot or kato nwar is a sombre-coloured, medium-sized parrot endemic to the Seychelles. Historically, it has been treated as a subspecies of the lesser vasa parrot, although it shows morphological, ecological and behavioural differences. Recent phylogenetic research indicates that the Seychelles population has a long history of isolation and may be sister to the rest of Coracopsis. It is the national bird of the Seychelles.

The Malagasy kestrel, also known as the Madagascar kestrel, Malagasy spotted kestrel, Newton's kestrel, Madagascar spotted kestrel, katiti (Creole) or hitsikitsika (Malagasy), is a small bird of prey of the genus Falco. It is named after British ornithologist Edward Newton. It occurs in two subspecies on Madagascar and at Aldabra. The race from Aldabra is also called Aldabra kestrel. Its closest living relative is the Seychelles kestrel; they were at one time considered conspecific. Their common ancestors appear to have diverged very recently, probably less than 1 million years ago during the Early or Middle Pleistocene. The Mauritius kestrel is more distantly related.(Groombridge et al. 2002)

Nelicourvi weaver Species of bird

The nelicourvi weaver is a species of bird in the family Ploceidae. It is endemic to Madagascar. Together with its closest relative, the sakalava weaver, it is sometimes placed in a separate genus Nelicurvius. A slender, sparrow-like bird, it is 15 cm (5.9 in) long and weighing 20–28 g (0.71–0.99 oz). Breeding males have a black bill and head, brown eyes, yellow collar, grey belly, chestnut-brown lower tail coverts, olive back, and blackish flight feathers edged greenish. Non-breeding males have mottled grey and green heads. In the breeding female the front of the head is yellow and the back olive green, with a broad yellow eyebrow. It builds solitary, roofed, retort-shaped nests, hanging by a rope from a branch, vine or bamboo stem, in an open space. It primarily feeds on insects, looking on its own or in very small groups, often together with long-billed bernieria. Its natural habitat is subtropical or tropical moist lowland and mountain forests. The conservation status of Nelicourvi weaver is least concern according to the IUCN Red List.

American barn owl Species of owl

The American barn owl is usually considered a subspecies group and together with the western barn owl group, the eastern barn owl group, and sometimes the Andaman masked owl, make up the barn owl, cosmopolitan in range. The barn owl is recognized by most taxonomic authorities. A few separate them into distinct species, as is done here. The American barn owl is native to North and South America, and has been introduced to Hawaii.
