Kestrel belongs to which the following families?

The common kestrel is a bird of prey species belonging to the kestrel group of the falcon family "Falconidae". 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.

Common kestrels measure 32–39 cm (12+1⁄2–15+1⁄2 in) from head to tail, females are noticeably larger. In the cool-temperate parts of its range, the common kestrel migrates south in winter.

When hunting, the common kestrel characteristically hovers about 10–20 m (35–65 ft) above the ground, searching for prey, either by flying into the wind or by soaring using ridge lift. 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. 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.
