The author studied the contents of 1421 cast pellets of the following Argentinian owls: Barn Owl, Tyto alba tuidara (3 samples of 1215, 116 and 58 pellets); Great Horned Owl, Bubo virginianus nacurutu (2 samples of 14 and 18 pellets) and Burrowing Owl, Athene cuniculariapartridgei (10 pellets). The results are presented in tables with the following information: place, date, prey species, numbers of individuals in each prey species, present of each prey species on total prey, and a two variable code representing main prey species (AP) and secondary prey species (AS). The principal conclusions of the prey mammals studied are: Oligoryzomys is a valid genus. Bibimys sp. and Colomys laucha ssp., coexisting in Misiones Province. The presence of Holochilus brasiliensis ssp. is verified in the Misiones Province. Oligoryzomys flavescens antoniae ssp. nov. is described. Bibimys torresi Massoia, 1978, is cited for the first time in Entre Rios Province.
