Short-Eared Owl Welfare: Vole Cycles and Upland Habitat in the UK

Short-eared owls are nomadic hunters of open moorland and grassland, with welfare and breeding success closely tied to field vole population cycles and the extent of undisturbed upland habitat.

Key Facts

Short-eared owls are diurnal hunters often seen quartering moorland in daylight hours
UK breeding populations fluctuate dramatically between years depending on field vole abundance
The species has declined significantly as a breeding bird — increased sheep grazing reduces suitable rough grassland prey habitat
Short-eared owls migrate to the UK from Scandinavia in winter, boosting resident populations

Welfare Considerations

Short-eared owls in low vole years face nutritional stress that reduces breeding attempts and fledgling survival. Owls that attempt to breed in poor prey years exhaust themselves provisioning chicks with insufficient food. Predation by foxes and mink at upland nesting sites causes nest failure and adult injury. Vehicle strikes on road verges where owls hunt cause acute traumatic injury. Wind turbine development on upland moors removes hunting habitat and creates collision risk for low-flying quartering owls.

What You Can Do

Support upland grassland restoration that increases field vole prey for short-eared owls and other raptors
Participate in BTO Bird Atlas surveys contributing short-eared owl population monitoring data
Advocate for raptor impact assessments that include short-eared owls in upland wind energy planning
Donate to Upland Skies project and RSPB upland bird conservation programmes
