Barn Owl Welfare and Habitat Provision

Barn owls have recovered from historic population lows but face ongoing welfare challenges from rodenticide poisoning, traffic mortality and nest site scarcity in modern agricultural landscapes.

Key Facts

Barn owl populations in the UK declined severely during the 20th century due to agricultural change and rodenticides
They have partially recovered following nest box programmes and some habitat improvements
Second-generation anticoagulant rodenticides are found in the majority of barn owls tested post-mortem
Road traffic mortality is the largest single cause of barn owl death - they fly low along road verges
Barn owls require open rough grassland with abundant small mammals, particularly field voles
Nest box schemes have been highly successful - thousands of pairs now nest in artificial boxes

Welfare Considerations

Barn owl welfare is significantly affected by rodenticide poisoning and road traffic mortality. Owls that ingest rodenticide-poisoned prey accumulate the toxins and may die from internal haemorrhage or be debilitated before death. Road casualties result from low-flying hunting behaviour that brings owls into vehicle paths. Practical welfare interventions are accessible to landowners and householders: installing nest boxes provides breeding sites, managing rough grass margins provides hunting habitat and using rodenticides only as a last resort after other pest control methods reduces poisoning risk. Reporting casualties to monitoring schemes improves our understanding of mortality causes.

What You Can Do

Install a barn owl nest box on suitable rural or semi-rural land and monitor it with the Barn Owl Trust
Manage grass margins and field edges as uncut rough grassland for vole habitat
Avoid second-generation anticoagulant rodenticides and use humane, non-toxic alternatives where possible
Support the Barn Owl Trust nest box and monitoring schemes
Report barn owl road casualties to the Barn Owl Trust for mortality data
