Wild Barn Owl Prey Availability Welfare

Barn owl hunting success depends on vole population cycles and field margin habitat, directly affecting individual welfare outcomes.

Key Facts

Barn owls are specialists on short-tailed field voles in most of their UK range
Vole population cycles of 3-4 years cause corresponding barn owl breeding success variation
Field margin management creating rough tussocky grass significantly increases vole availability
Barn owls may travel up to 10km in a night when local prey is scarce

Welfare Considerations

Barn owls in vole-poor landscapes experience nutritional stress and reduced breeding success. In poor vole years, adults may be unable to provision chicks adequately causing nestling starvation. Habitat management supporting stable vole populations reduces the severity of poor year welfare impacts.

What You Can Do

Encourage field margin and rough grassland creation on your land
Support farm management advice including barn owl habitat planning
Report barn owl sightings and breeding activity to the Barn Owl Trust
