Barn Owl Welfare: Rodenticide Risk and Nest Box Support

Overview of barn owl welfare challenges, rodenticide poisoning risk, and nest box conservation.

Key Facts

UK barn owl population estimated at 4,000-5,000 breeding pairs
Secondary rodenticide poisoning is a significant welfare and conservation concern
Barn owls require open grassland with abundant small mammal prey
Nest box schemes have contributed significantly to population stabilisation
Severe winters with prolonged snow cover cause high barn owl mortality

Welfare Considerations

Barn owl welfare is shaped by rodenticide poisoning risk, habitat quality, and winter severity. Secondary poisoning from rodenticides applied in farm buildings is a major concern, with many surveyed barn owls showing detectable levels. Barn owl nest box schemes have been effective conservation tools. Reducing rodenticide risk through integrated pest management is a critical welfare priority.

What You Can Do

Install barn owl nest boxes on suitable farmland and grassland habitat
Support campaigns to reduce agricultural rodenticide use
Record barn owl sightings through BTO Barn Owl Survey
