The greatest concentrations are found in low-lying arable areas where prey is abundant. The Barn Owl nests in hollow trees, buildings and crevices in rocks.


The Barn Owl was once a familiar sight in the British countryside. As its name suggests, it was frequently found in and near farm buildings, where it was welcomed by farmers because of its usefulness in pest control. A pair of Barn Owls and their young may eat about 1,000 rodents between them during the three month breeding season.

Though there is no reason to suppose that the Barn Owl did not reach Wales under its own steam, if humans had not cleared the original forest cover back in Neolithic times some 5,000 years ago, there would have been precious little habitat for it to colonise at all. In fact, the Barn Owl is really a bird of tropical savannah which has been able to take advantage of agricultural clearances in more temperate zones such as ours.

Unfortunately, as 20th Century farming methods led to the destruction of hedgerows, meadowland and field headlands – with the consequent loss of habitats for prey species – and as old farm buildings were either demolished or converted to other uses, the Barn Owl population has crashed to a dangerously low level.
