Wild Barn Owl Conservation Welfare

Barn owls are one of Britain's most beloved birds of prey, but their welfare is threatened by road mortality, rodenticide poisoning, and cold wet winters that reduce prey availability.

Key Facts

UK barn owl populations are approximately 5,000-10,000 pairs with significant annual fluctuation
Road mortality is the leading cause of barn owl death - they hunt low along roadsides and are struck by vehicles
Cold wet winters cause mass barn owl mortality as voles and field mice become inaccessible under snow
Second-generation anticoagulant rodenticides (SGARs) are found in the livers of the majority of barn owls tested
Nest box provision has been one of the most successful welfare and conservation interventions for barn owls

Welfare Considerations

Barn owl welfare faces both acute and chronic threats. Road mortality causes instantaneous death but in aggregate removes thousands of birds annually from the population. SGAR poisoning causes sub-lethal health effects including impaired hunting performance and internal bleeding that may eventually be fatal. Cold winters causing prey inaccessibility leads to starvation - barn owls have low fat reserves and can die within days of prey unavailability. Nest box provision is the most direct positive welfare intervention available, providing safe nesting sites that increase breeding success.

What You Can Do

Install barn owl nest boxes in suitable rural locations following guidance from the Barn Owl Trust
Avoid using second-generation anticoagulant rodenticides that bioaccumulate in barn owl tissues
Drive carefully on rural roads at night, particularly in areas where barn owls hunt verge edges
Report dead barn owls to the Barn Owl Trust for monitoring and SGAR testing
