The barn owl is one of the most popular birds in Britain but is now extremely rare. The bird favors open habitats such as grasslands, hedgerows, the edges of fields or woodlands, stubble fields, drainage ditches, and farmyards.
The barn owl is a carnivore and hunts for its favorite diet of small mammals and birds. It usually flies slowly back and forth, about three meters above the ground, using its large eyes and sensitive hearing to spot likely prey. If suitable perches, such as fence posts, are available, the bird may save energy by hunting from these. Once it has swooped silently down, a hooked beak tears into the victim. Food is often swallowed whole and the indigestible parts, such as the bones and fur, are regurgitated in the form of pellets.
When seen in flight, the general impression is of a large white bird. However, the upper parts are a beautiful golden buff color, delicately marked in varying shades of buff and grey. It is only the face, breast, and undersides that are mostly white.
After choosing a suitable hole in a tree or a ledge in an old building, the female barn owl lays between four and seven eggs in April each year. The owlets are fully developed after ten weeks and leave the nest after about fourteen weeks, by which time they must be able to survive alone. As many as one in four young barn owls die within a year for a variety of reasons.
The number of barn owls in Britain is decreasing. There are now fewer habitats where they can find mice, voles, and other prey. In some areas, owls have been affected by chemicals and cannot lay proper eggs. This means that they cannot breed and increase their numbers. In addition, many birds have been killed accidentally as they fly across major roads and motorways. The barn owl is one of nature's most graceful hunters. Many organizations in Britain, such as the Barn Owl Trust in the South West, are working towards
their conservation.
