Barn owls are one of Britain's most beloved birds but have declined significantly due to habitat loss and rodenticide poisoning, making targeted conservation essential.
Barn owls poisoned by rodenticides suffer from internal haemorrhage and coagulopathy before death. Road traffic collisions cause traumatic injury and death. Starvation in severe winters affects entire populations. Individual welfare is interwoven with population welfare: a species at low population density faces higher welfare risks per individual from disease, winter mortality, and collision. Nest box provision, rodenticide reduction, and rough grassland restoration all directly benefit individual barn owl welfare and survival.
