The apparent decline in occupancy in 2012 and 2013 may have been due to the inclusion of newly-erected boxes, some of which were not at traditional sites, hence were less likely to be occupied. The large numbers of non-breeding birds seen in 2011 wasn’t replicated in 2012, and whilst clutch sizes were slightly smaller this year, average brood size remained around the same level.
2013 saw one of the worst years for Barn Owls across the country, with a large numbers of sites unoccupied for the first time in many years. Those that did breed had smaller clutches and smaller broods than in previous years. In contrast, 2014 was an excellent season, with much larger broods of chicks seen and over three times as many chicks ringed as in 2013!
