Barn Owl Conservation Welfare

Barn owl populations face threats from habitat loss and rodenticide use; conservation action directly improves individual and population welfare.

Key Facts

UK barn owl populations are estimated at 4,000-5,000 breeding pairs
Second-generation anticoagulant rodenticides (SGARs) kill owls that eat poisoned prey
Nest box schemes have significantly increased breeding success in suitable habitat
Road mortality is a significant cause of death particularly for dispersing young
Grassland management maintaining rough grass margins improves hunting success

Welfare Considerations

Barn owls poisoned by rodenticides suffer prolonged coagulopathy causing internal haemorrhage before death, representing a welfare cost that can be substantially reduced through alternative pest control. Individual owls rehabilitated from rodenticide poisoning, collision injury, or starvation demonstrate the welfare benefit of both preventive conservation and responsive care.

What You Can Do

Install barn owl nest boxes in suitable rural locations
Switch to humane alternatives to second-generation rodenticides
Report dead barn owls for residue testing to wildlife health organisations
Manage field margins as rough grassland to support owl hunting habitat
Support the Barn Owl Trust and similar conservation organisations
