Barn Owl Conservation and Welfare: Supporting a Threatened Farmland Species

Barn owls have declined significantly across their range. Supporting their conservation through habitat management benefits both the species and farmland ecosystem welfare.

Key Facts

Barn owl populations have declined by over 70% in the UK since the mid-20th century due to habitat and prey loss
Rodenticide poisoning is a significant cause of barn owl mortality as they consume poisoned prey
Nest box provision has partially compensated for loss of suitable nesting sites in old farm buildings
Barn owls require short-cut grassland with high small mammal density for successful hunting
They are highly vulnerable to road mortality, particularly in their first winter of life
Cold and wet winters cause high mortality through prey inaccessibility and thermoregulation challenges

Welfare Considerations

Barn owl welfare and conservation are inseparable: the welfare challenges this species faces are primarily driven by habitat loss, prey depletion, and poisoning in agricultural landscapes. Individual barn owls experiencing rodenticide secondary poisoning suffer neurological damage before death. Fledglings dispersing from natal territories face their greatest risk in their first winter when hunting skills are still developing and road crossings are frequent. Supporting barn owl populations through habitat management, nest box provision, and reduced rodenticide use on farmland addresses both species conservation and the welfare of individual birds within the population.

What You Can Do

Install a barn owl nest box on appropriate rural properties following guidance from the Barn Owl Trust
Advocate for reduced second-generation rodenticide use on farmland where barn owl populations exist
Support agri-environment scheme uptake by farmers providing rough grassland margins and reduced mowing
Report barn owl sightings to national recording schemes to support population monitoring
Donate to the Barn Owl Trust or equivalent organisations providing habitat and nest site support
