Wild Barn Owl Rodenticide Risks

Secondary poisoning from rodenticides poses a significant threat to barn owls across the UK, with widespread detection in dead and live birds.

Key Facts

Studies find rodenticide residues in over 80% of barn owls tested in UK
Second-generation anticoagulant rodenticides are most dangerous
Owls accumulate poison by eating poisoned rodents over time
Sublethal doses affect coordination and hunting ability before death
Barn owl populations are stable but rodenticide is a significant ongoing threat

Welfare Considerations

Rodenticide poisoning causes a prolonged, distressing death from internal bleeding. Sublethal exposure affects barn owls' ability to hunt effectively, causing starvation. Switching to first-generation rodenticides and using bait stations that prevent access to non-target species dramatically reduces owl exposure.

What You Can Do

Never use second-generation rodenticides outdoors where owls hunt
