Wild Barn Owl Prey Availability and Vole Cycles

Barn owl welfare and breeding success are intimately linked to field vole population cycles. Understanding this relationship is essential for conservation management.

Key Facts

Field voles are the primary prey of barn owls in most UK habitats
Vole populations follow three to four year cycles affecting barn owl breeding success dramatically
Barn owls may fail to breed entirely in years of low vole availability
Rough grassland management supporting high vole density is the primary habitat conservation tool
Barn owls have exceptional low-light vision and hearing enabling hunting in almost complete darkness

Welfare Considerations

Barn owl welfare is inseparable from prey availability. Conservation management that maintains rough grassland with high vole populations directly supports barn owl welfare through reliable food access.

What You Can Do

Support Barn Owl Trust surveys to monitor breeding success and vole availability
Advocate for rough grass margins on farmland as barn owl foraging habitat
Install nest boxes in areas with good prey habitat to support barn owl populations
