Common kestrel (Falco tinnunculus)

Key characteristics

Common kestrels are medium-sized falcons with long wings and a relatively long tail. Males and females differ: males typically show greyer heads and tails with clearer rufous back markings, while females are browner and more streaked overall. Their flight is buoyant and powerful; they are especially noted for their ability to hover stationary over open ground while searching for prey, a behaviour often called "kestrel hovering." Visually acute, kestrels locate small mammals, insects and other prey from both a perch and while hovering.

Distribution and habitat

The species has a broad Old World range and tolerates many environments, including farmland, heathland, parkland, coastal cliffs and even urban areas where suitable perches and nest sites are available. Some populations are resident year-round, while birds breeding in colder regions may move to milder areas in winter. Subregional forms and subspecies reflect adaptation to local climates and landscapes.

Diet, hunting and behaviour

• Diet: primarily small mammals (such as voles and mice), large insects, and occasionally small birds and reptiles.
• Hunting methods: perch-hunting, low fast flight and the characteristic hovering to locate ground-dwelling prey.
• Social behaviour: generally solitary or in pairs, but may be seen in loose groups at rich feeding sites.

Reproduction, conservation and human interactions

Kestrels nest in cavities, cliff ledges, old buildings and nest boxes; they do not commonly build a substantial nest structure but lay a clutch of several eggs which both parents help to raise. The species is generally widespread and adaptable and is not considered globally threatened; many populations are classed as of low conservation concern, although local declines occur where habitat or prey declines are severe. The kestrel has cultural recognition in many places and, while less commonly used than larger falcons, has featured in traditional falconry practices.
