The crepuscular/nocturnal Mus musculus was the main prey for the diet of breeding Barn Owls (81% and White-tailed Kites (63%. ![]() Based on the daily activity period of their main small mammal prey, a lower overlap would be expected.

The objective was to evaluate how these raptors, which differ markedly in their hunting activity periods (owls are nocturnal and kites diurnal, share their mammalian food component. Food partitioning between breeding White-tailed Kites (Elanus leucurus Aves Accipitridae and Barn Owls (Tyto alba Aves Tytonidae in southern Brazilĭirectory of Open Access Journals (Sweden)įull Text Available I examined the diet of breeding White-tailed Kites (Elanus leucurus Aves Accipitridae and Barn Owls (Tyto alba Aves Tytonidae in an agrarian area of southern Brazil by analyzing regurgitated prey remains. ![]()
