Short-eared owls are diurnal hunters of open moorland and coastal habitats whose welfare depends on vole prey availability and undisturbed hunting grounds.
Short-eared owl welfare is primarily determined by prey availability. Field vole populations cycle dramatically, and owls breed most successfully in years of high vole density. Hunting territory quality — open ground with dense vole populations — determines body condition and breeding success. Disturbance from birdwatchers and photographers at known hunting sites causes energy-costly flight responses that may impair welfare during energetically demanding periods. Respectful observation practices protect individual owl welfare.
