In this study we report on spatial ecology and habitat selection of Little Owls during their breeding season in an agricultural landscape and discuss key management actions for its conservation. The mean home range size of radio-tracked Little Owls, determined by the kernel method, was 0.94 ha and 4.30 ha for 50% and 95% home range, respectively. The smallest home ranges were recorded in April–June (incubation and nesting period) with a significant increase in July–August (fledging season). The most important foraging habitat during the entire breeding season was grassland (especially pastures) reaching 90% for all locations. Vegetation height and cover were the main factors determining habitat selection: Little Owls significantly preferred sparse and short sward vegetation patches that enabled hunting of ground-dwelling prey. Conservation efforts for Little Owls should focus on the active management of prey-rich grassland habitats in the vicinity of breeding sites.
