Barn Owl Welfare: Supporting a Farming Landscape Predator

Barn owls are among the most beloved British birds but face serious welfare challenges from road mortality, rodenticide poisoning, and nest site loss. Targeted interventions can substantially reduce these threats.

Key Facts

Britain supports approximately 4,000 pairs of barn owls -- one of the larger European populations
Road mortality kills thousands of barn owls annually -- they hunt low over verges and cross roads at car height
Secondary poisoning from anticoagulant rodenticides affects an estimated 90% of barn owls in some studies
Barn owls require large territories of rough grassland with adequate vole populations for successful breeding
Nest box installation programmes have significantly increased nesting opportunities in arable landscapes
The Barn Owl Trust operates one of the largest barn owl conservation programmes in the world
Barn owls have zero fat reserves -- a single week of poor hunting weather during winter can be fatal

Welfare Considerations

Barn owl welfare is severely affected by three largely preventable threats. Road mortality causes acute traumatic death for owls hunting roadside verges. Anticoagulant rodenticide poisoning causes internal bleeding, lethargy, and death over several days -- a prolonged welfare harm. Starvation during periods of snow cover or cold weather causes suffering and death in animals with no fat reserves. All three threats are addressable through specific interventions: roadside vegetation management that discourages hunting on verges, switching to non-anticoagulant pest control, and nest box provision that enables pairs to breed.

What You Can Do

Install a barn owl nest box in suitable habitat -- the Barn Owl Trust provides guidance on specifications
Switch from anticoagulant to non-anticoagulant rodenticide alternatives to prevent barn owl secondary poisoning
Maintain rough grassland margins on farmland to provide vole habitat that barn owls depend on for food
Support the Barn Owl Trust through donation -- they provide nest boxes and monitor populations nationally
Advocate for road verge management that reduces barn owl hunting on dangerous road margins
