Wild Barn Owl Winter Survival Welfare

Barn owls are particularly vulnerable during winter periods - supplementary feeding and nest box provision directly improve individual survival rates.

Key Facts

Barn owls can starve in prolonged snow cover when voles are inaccessible
Body weight below 270g in adults indicates dangerous starvation risk
Nest box provision doubled barn owl breeding density in some UK studies
Rodenticide-contaminated prey is a major cause of barn owl mortality year-round
Winter is the period of highest barn owl mortality, particularly for first-year birds

Welfare Considerations

Individual barn owls face real, measurable welfare challenges during winter. Supplementary feeding during extreme weather, nest box provision, and rodenticide reduction are direct welfare interventions with proven population benefits.

What You Can Do

Install barn owl nest boxes in suitable locations following guidance
Avoid second-generation rodenticides that poison barn owls through contaminated prey
Donate to barn owl conservation trusts providing winter feeding and monitoring
