Wild Animal Welfare

Wild Barn Owl Prey Population Welfare

Barn owl welfare depends on abundant vole prey - prey population dynamics directly determine individual owl nutrition, breeding success, and survival.

Key Facts

Vole population cycles of 3-4 years create predictable boom and bust conditions for barn owls
In poor vole years, barn owls may fail to breed or abandon eggs and chicks
Vole habitat of rough tussocky grassland has declined with agricultural intensification
Supplementary feeding during vole crashes can prevent individual starvation
Maintaining rough grassland at field margins creates sustainable vole habitat benefiting owls

Welfare Considerations

Barn owl welfare is inseparable from vole prey abundance. Individual owls in territories with rich rough grassland vole habitat experience better nutrition, higher breeding success, and lower winter mortality than those in prey-poor territories.

What You Can Do

Support agri-environment schemes that create rough tussocky grassland vole habitat
Advocate for field margin management that maintains vole populations
Join barn owl monitoring groups that track the relationship between prey and owl welfare
