Common kestrel - Wikipedia. The common kestrel (Falco tinnunculus) is a bird of preyspecies belonging to the kestrel group of the falconfamily. Falconidae. It is also known as the European kestrel, Eurasian kestrel, or Old World kestrel. In Britain, where no other kestrel species occurs, it is generally just called "the kestrel".[2]This species occurs over a large range. It is widespread in Europe, Asia, and Africa, as well as occasionally reaching the east coast of North America[citation needed]. But although it has colonized a few oceanic islands, vagrant individuals are generally rare; in the whole of Micronesia for example, the species was only recorded twice each on Guam and Saipan in the Marianas.[3][4][5]Description[edit]Common kestrels measure 3.

They are thus small compared with other birds of prey, but larger than most songbirds. Like the other Falcospecies, they have long wings as well as a distinctive long tail.[3]Their plumage is mainly light chestnut brown with blackish spots on the upperside and buff with narrow blackish streaks on the underside; the remiges are also blackish. Unlike most raptors, they display sexual colour dimorphism with the male having fewer black spots and streaks, as well as a blue- grey cap and tail.

All common kestrels have a prominent black malar stripe like their closest relatives.[3]The cere, feet, and a narrow ring around the eye are bright yellow; the toenails, bill and iris are dark. Juveniles look like adult females, but the underside streaks are wider; the yellow of their bare parts is paler. Hatchlings are covered in white down feathers, changing to a buff- grey second down coat before they grow their first true plumage.[3]Adult male F. Young male F. t. tinnunculus during ringing.

Behaviour and ecology[edit]In the cool- temperate parts of its range, the common kestrel migrates south in winter; otherwise it is sedentary, though juveniles may wander around in search for a good place to settle down as they become mature. It is a diurnal animal of the lowlands and prefers open habitat such as fields, heaths, shrubland and marshland. It does not require woodland to be present as long as there are alternative perching and nesting sites like rocks or buildings. It will thrive in treeless steppe where there are abundant herbaceous plants and shrubs to support a population of prey animals. The common kestrel readily adapts to human settlement, as long as sufficient swathes of vegetation are available, and may even be found in wetlands, moorlands and aridsavanna. It is found from the sea to the lower mountain ranges, reaching up to 4,5. ASL in the hottest tropical parts of its range but only to about 1,7. Himalayanfoothills.[3][6]Globally, this species is not considered threatened by the IUCN.[1] Its stocks were affected by the indiscriminate use of organochlorines and other pesticides in the mid- 2. The global population is fluctuating considerably over the years but remains generally stable; it is roughly estimated at 1–2 million pairs or so, about 2. Europe. There has been a recent decline in parts of Western Europe such as Ireland. Subspecies dacotiae is quite rare, numbering less than 1. Canarian subspecies canariensis numbered about ten times as many birds.[3]Food and feeding[edit]When hunting, the common kestrel characteristically hovers about 1. Like most birds of prey, common kestrels have keen eyesight enabling them to spot small prey from a distance. Once prey is sighted, the bird makes a short, steep dive toward the target. It can often be found hunting along the sides of roads and motorways. This species is able to see near ultraviolet light, allowing the birds to detect the urine trails around rodent burrows as they shine in an ultraviolet colour in the sunlight.[7] Another favourite (but less conspicuous) hunting technique is to perch a bit above the ground cover, surveying the area. When the birds spots prey animals moving by, they will pounce on them. They also prowl a patch of hunting ground in a ground- hugging flight, ambushing prey as they happen across it.[3]European pine vole (Microtus subterraneus), a typical common kestrel prey since prehistoric times. Common kestrels eat almost exclusively mouse- sized mammals. Voles, shrews and true mice supply up to three- quarters or more of the biomass most individuals ingest. On oceanic islands (where mammals are often scarce), small birds (mainly passerines) may make up the bulk of its diet.[5] Elsewhere, birds are only an important food during a few weeks each summer when inexperienced fledglings abound. Other suitably sized vertebrates like bats, swifts,[8]frogs[citation needed] and lizards are eaten only on rare occasions. However, kestrels are more likely to prey on lizards is southern latitudes. In northern latitudes, the kestrel is found to more often deliver lizards to their nestlings during midday and also with increasing ambient temperature.[9] Seasonally, arthropods may be a main prey item. Generally, invertebrates like camel spiders and even earthworms, but mainly sizeable insects such as beetles, orthopterans and winged termites are eaten with delight whenever the birds happen upon them.[3]F. They have been known to catch several voles in succession and cache some for later consumption. An individual nestling consumes on average 4. Reproduction[edit]The common kestrel starts breeding in spring (or the start of the dry season in the tropics), i. April or May in temperate. Eurasia and some time between August and December in the tropics and southern Africa. It is a cavity nester, preferring holes in cliffs, trees or buildings; in built- up areas, common kestrels will often nest on buildings, and generally they often reuse the old nests of corvids if these are available. The diminutive subspeciesdacotiae, the sarnicolo of the eastern Canary Islands is peculiar for nesting occasionally in the dried fronds below the top of palm trees, apparently coexisting rather peacefully with small songbirds which also make their home there.[1. In general, common kestrels will usually tolerate conspecifics nesting nearby, and sometimes a few dozen pairs may be found nesting in a loose colony.[3]. Male F. t. tinnunculus bringing food to nest. The clutch is normally 3–6 eggs, but may contain any number of eggs up to seven; even more eggs may be laid in total when some are removed during the laying time, which lasts about 2 days per egg laid. The eggs are abundantly patterned with brown spots, from a wash that tinges the entire surface buffish white to large almost- black blotches. Incubation lasts some 4 weeks to one month, and only the female hatches the eggs. The male is responsible for provisioning her with food, and for some time after hatching this remains the same. Later, both parents share brooding and hunting duties until the young fledge, after 4–5 weeks. The family stays close together for a few weeks, up to a month or so, during which time the young learn how to fend for themselves and hunt prey. The young become sexually mature the next breeding season.[3]Data from Britain shows nesting pairs bringing up about 2–3 chicks on average, though this includes a considerable rate of total brood failures; actually, few pairs that do manage to fledge offspring raise less than 3 or 4. Population cycles of prey, particularly voles, have a considerable influence on breeding success. Most common kestrels die before they reach 2 years of age; mortality up until the first birthday may be as high as 7. At least females generally breed at one year of age; [1.

Evolution and systematics[edit]This species is part of a clade that contains the kestrel species with black malar stripes, a feature which apparently was not present in the most ancestral kestrels. They seem to have radiated in the Gelasian (Late Pliocene,[1. East Africa, as indicated by mt. DNAcytochrome bsequence data analysis and considerations of biogeography. The common kestrel's closest living relative is apparently the nankeen or Australian kestrel (F.

Both species have much grey in their wings in males, which does not occur in the common kestrel or its close living relatives but does in almost all other falcons. Subspecies[edit]A number of subspecies of the common kestrel are known, though some are hardly distinct and may be invalid. Most of them differ little, and mainly in accordance with Bergmann's and Gloger's Rules. Tropical African forms have less grey in the male plumage.[3]Falco tinnunculus tinnunculus.
