The barn owl population in the UK has recovered from a low of around 4,000 pairs in the 1990s to an estimated 14,000+ pairs today, largely through nest box provision and changes in land management. Ongoing threats require continued monitoring.
Barn owls injured in road collisions require specialist wildlife veterinary care and often have complex orthopedic injuries. SGAR poisoning causes internal hemorrhaging — affected owls are often found unable to fly or stand, and die from internal bleeding if not treated. The experience of SGAR poisoning, involving progressive weakness and internal hemorrhage, represents real suffering. Nest box provision directly improves breeding success by providing secure sites that are otherwise scarce in modern landscapes. Winter feeding programs near nest boxes are controversial but may support survival during prolonged cold spells when voles are inaccessible under snow.
