The Barn Owl was once a familiar sight in the British countryside, frequently found in and near farm buildings, where it was welcomed by farmers because of its usefulness in pest control.

Unfortunately, farming methods of the last century led to the destruction of hedgerows, meadowland and field headlands with the consequential loss of habitat for prey species, a factor which the increased use of pesticides then accelerated. As old farm buildings were either demolished or converted to other uses, the Barn Owl population crashed to a dangerously low level and by the year 2000 it was estimated there were less than 4,000 breeding pairs left in Britain.

Although changes in agricultural practices have to a certain extent halted and in some cases reversed this decline, traffic deaths now play an increasing part in keeping Barn Owls at Amber status on the British Birds Conservation List.

Though widespread throughout Britain but scarce or absent from the highlands & islands of Scotland, Barn Owls are found in low-lying arable areas near coasts, where prey is abundant; farmland with hedgerows and copses; uncultivated areas such as heaths and marshes; and sometimes large gardens, or even occasionally in villages close to fields They nest in hollow trees, buildings and crevices in rocks.

The Barn Owl’s prey consists mainly of small mammals, in particular short-tailed and field voles, mice and common shrews. These it either still-hunts from a perch or searches for by quartering over meadowland, usually in the half-light at dusk or dawn and often hovering with moth-like silent fluttering flight as it relies on its superb hearing to locate prey. It is estimated that a pair of Barn Owls and their young may eat about 1,000 rodents between them during the three-month breeding season.

The Barn Owl has a distinctive heart shaped face, buff back and wings and pure white under parts (which often lead to it being incorrectly identified as a Snowy Owl when seen in head-on flight). Although flight is silent, the screeching, wheezing and gurgling of the Barn Owl gives it an unique aural signature.
