The '''Common barn owl''' (''Tyto alba'') is a species of [[owl]] in the [[genus]] ''Tyto''. It is the most widely distributed species of owl, and one of the most widespread of all birds. The barn owl family [[Tytonidae]] is one of two main lineages of living owls, the other being the typical owls ([[Strigidae]]). It is known by many other names in different parts of the world, which is one of the problems with 'common names'. It is one of the main reasons [[Linnaeus]] invented his system of [[Binomial nomenclature|scientific naming]].

This owl has long wings, a pale face, and a square-shaped tail. It lives in rural areas like [[farm]]s and [[woodland]]. The barn owl has a [[wing span]] of 75–110 cm and its body length measures up to around 25–50 cm. It weighs between 187 and 800 grams.

Barn owls' [[breeding season]] is [[spring]] and it breeds in nests in trees. It eats small mammals, reptiles, fish, insects and smaller birds.

==Ecology==

''Tyto alba'' is [[nocturnal]], as usual for owls. However, it often becomes active shortly before [[dusk]] and can sometimes be seen during the day, when it moves from a sleeping place it does not like.

This is a [[bird]] of open country such as [[arable land|farmland]] or [[grassland]] with some interspersed [[woodland]]. This owl prefers to hunt along the edges of woods. It has an effortless wavering flight as it moves over pastures or similar hunting grounds. Like most owls, the Barn Owl flies silently; tiny serrations on the leading edges of its [[flight feather]]s help to break up the flow of air over its wings, thereby reducing [[turbulence]] and the noise that accompanies it.<ref name=Ehrlich>Ehrlich, Paul R; Dobkin, David S; Wheye, Darryl & Pimm, Stuart L. 1994. ''The birdwatcher's handbook: a guide to the natural history of the birds of Britain and Europe''. Oxford University Press. {{ISBN|0-19-858407-5}}</ref>

===Diet and feeding===
[[File:Chouette crâne (2).jpg|thumb|A Barn Owl skull, showing the rodent-killer beak]]
It hunts by flying low and slowly over an area of open ground, hovering over spots that conceal potential prey. They may also use fence posts or other lookouts to ambush prey. The Barn Owl feeds primarily on small [[vertebrate]]s such as [[rodent]]s.<ref name=Ehrlich/>

Studies have shown that an individual Barn Owl may eat one or more rodents per night; a nesting pair and their young can eat more than 1,000 rodents per year. Locally superabundant rodent species in the weight class of several grams per individual usually make up most of the prey. Such animals probably make up at least three-quarters of the [[biomass]] eaten by each and every ''T. alba'', except in some island populations. In [[Ireland]], the accidental introduction of the [[Bank vole]] in the 1950s has led to a major shift in the Barn Owl's diet: where their ranges overlap the vole is now by far the largest prey item.<ref>Kelleher, Oliver and Sleeman 2011. ''Irish Birds'' Volume 9.</ref> The diet is supplemented with local small [[vertebrate]] and large [[invertebrate]] life.
