Short-Eared Owl: Nomadic Vole Specialist

Short-eared owls are unusual diurnal owls whose welfare is tied to field vole population cycles on upland grasslands.

Key Facts

Short-eared owls are the most diurnal UK owl regularly hunting in daylight
UK breeding population fluctuates with vole cycles from under 500 to over 1,500 pairs
They nest on the ground in heather or rough grass
Winter influxes from Scandinavia supplement the resident population
Short-eared owls can breed opportunistically in response to high vole density

Welfare Considerations

Short-eared owl welfare depends entirely on field vole availability. Population crashes follow vole declines in moorland areas. Inappropriate moorland management including overgrazing and drainage reduces vole habitat. Road mortality affects birds hunting along road verges in winter. Illegal persecution on game estates takes a toll on this vulnerable species.

What You Can Do

Support upland grassland restoration that maintains dense field vole populations
Report suspected persecution of short-eared owls to RSPB and police
Drive carefully on upland roads particularly at dusk when owls hunt road verges
Support rewilding projects that restore rough grassland and heathland
Join BTO winter raptor surveys that track short-eared owl distribution
