The breeding season distribution of Barn Owls in Britain and Ireland as shown in the BTO Bird Atlas 2007-2011. Population Estimates and Reasons for Change
Devon and Cornwall The most detailed large-scale Barn Owl surveys carried out in the UK were the Devon Barn Owl Survey (1993, 2003, and 2013) and Cornwall Barn Owl Survey (1994, 2004). Together these give a very good impression of distribution on the southwest peninsula. Although rare, the species is well distributed but generally absent from upland areas and major road corridors. The 2003-04 population estimate for the two counties combined was 620 to 830 pairs (approx. 15-20% of the UK population at the time). A 2013 distribution map for Devon will be available from summer 2014.
