Food niche overlap in co-existing Barn Owl Tyto alba (Scopoli 1769) and Great Horned Owl Bubo virginianus Gmelin 1788 in intensively used farmland

179--181

The study was conducted at a site where the Great Horned Owl and the Barn Owl nested in a close proximity to each other in an intesivelly managed farmland in north-eastern Oregon. By the means of pellet content analysis it has been shown that food niches of both species almost totally overlapped. Their main diet was composed of Microtus voles (numerically: 79% in Great Horned Owl and 86% in Barn Owl) which were probably superabundant in this site.
