Resumen:
We studied the breeding ecology of burrowing owls (Athene cunicularia) in central Saskatchewan during 1982-83. We determined home range, activity patterns, and habitat used for foraging for 6 radio-tagged adult male owls. Owls used grass-forb areas for foraging and avoided croplands and grazed pasture. Mean home-range size was 2.41 km<sup>2</sup> (range = 0.14-4.81 km<sup>2</sup>). Peak foraging activity occurred between 2030 and 0630 hours. Ninety-five percent of all movements were within 600 m of the nest burrows. The nesting habitat requirements of short grass, open sites, and burrow availability can be met by managing and protecting existing historic sites.
