Barn Owl – report

Tyto alba – TYLLUAN WEN – Breeding resident.

The barn owl is a much admired and popular species, and its frequent use of artificial sites such as lofts and boxes for nesting, has led to them becoming the most comprehensively monitored of the owl species in UK as a whole.

Following major population declines during the 20th century there appears to have been a recovery in recent years (BTO Bird Atlas 2013). However, this apparent recovery is not evenly spread across all areas, and in the west of UK and in Ireland there is evidence of a range contraction and possibly an associated population decline.

In Pembrokeshire the status of barn owls has previously been described as “far from common” by both Mathew (1894) and Lockley (1949), while Lloyd (1925) considered them “uncommon” . A survey commissioned by RSPB in 1934 led to an estimate of 220 pairs in the county, and in Birds of Pembrokeshire (1994) Rees and Donovan suggest a total of around 100 pairs based on a general survey in 1984-88.

But what is the situation now? Read the full report:

All records of Barn Owl can be added to BirdTrack. If there is evidence of breeding, please select the appropriate code from the drop-down box. There is no need to enter a site to see evidence of breeding – an owl carrying food to a likely nesting place, or the calls of chicks are adequate evidence.
