Wild Animal Welfare: Barn Owl Conservation

Barn owls are a charismatic farmland species whose welfare is linked to traditional mixed farming landscapes. Their conservation is directly accessible to farmers and landowners.

Key Facts

UK barn owl population is estimated at around 4,000 pairs - relatively stable but historically much higher
Barn owls die from starvation more than any other cause - rough grassland vole habitat is essential
Road traffic kills around 4,000 barn owls annually in the UK - equivalent to the entire breeding population
Rodenticide poisoning (from eating poisoned prey) is a significant and growing welfare threat
Nest boxes placed in suitable buildings or on poles have proven highly effective at supporting barn owl populations
Barn owls cannot fish for food in hard winter conditions - prolonged snow cover causes rapid starvation

Welfare Considerations

Barn owl welfare is directly dependent on the presence of rough grassland habitat supporting vole populations. In areas where field margins and rough grassland have been replaced by intensive cultivation, barn owls starve. Individual owls experiencing starvation suffer a gradual, prolonged welfare decline - reducing weight, reducing foraging efficiency, and ultimately dying from exhaustion and hypothermia. The welfare interventions are clear: maintaining rough grassland margins, providing nest boxes in appropriate locations, and reducing rodenticide use on farms. The Barn Owl Trust provides detailed guidance on nest box installation and habitat management that any farmer or landowner can implement.

What You Can Do

Install a barn owl nest box on suitable farm buildings or poles following Barn Owl Trust guidance
Create or maintain rough grassland field margins to support vole populations
Reduce rodenticide use and use storage-area rodent management to reduce secondary poisoning
Drive slowly on rural roads at night - barn owls hunt at head height and are frequently struck
Support Barn Owl Trust habitat management and monitoring programmes
