The barn owl (Tyto alba) is the most widely distributed species of owl, and one of the most widespread of all birds. It is found in most parts of the world, with one major lineage in the New World, one in Australasia, and another in Eurasia and Africa. The 28 subspecies, between 33 and 39 cm in length, have wingspans ranging from 80 to 95 cm. Their colours vary, but most have mottled grey or brown plumage and paler underparts, with a white, heart-shaped face. The barn owl relies on acute hearing to detect small mammals and other prey, hunting almost exclusively at night. It does not hoot, but utters an eerie, drawn-out shriek. It mates for life unless one of a pair dies, when a new pair bond may be formed. The nest is in a hollow tree, old building or cliff; the female does all the incubation, and she and the young chicks rely on the male for food. When large numbers of small prey are available, barn owl populations can expand rapidly. Globally, the species is not threatened, except for some subspecies with restricted ranges.
