Wild Barn Owl Winter Survival

Barn owls are particularly vulnerable to winter mortality from cold, food scarcity, and road casualties, requiring targeted habitat and nest box support.

Key Facts

Barn owls have been declining in the UK, with an estimated 4,000 breeding pairs
Cold, wet winters cause high mortality as voles become inaccessible under frozen ground
Barn owl nest boxes have significantly supported populations in areas lacking old buildings
Road casualties are significant as owls hunt along road verges for small mammals
Rough grassland with high vole density is essential for barn owl foraging

Welfare Considerations

Barn owls in harsh winters face starvation if vole populations are inaccessible. Cold, wet conditions impair hunting success while increasing energy demands. The welfare cost of winter starvation is significant for individual owls. Nest box provision and rough grassland management provide crucial support.

What You Can Do

Install barn owl nest boxes on suitable farms and estates
Support Barn Owl Trust nest box programmes and surveys
Advocate for rough grassland margins in agri-environment schemes
