| Abstract: | In a sample of 91 pellets of the Barn Owl Tyto alba a total of 232 small mammals could be identified. They belong to the didelphid Monodelphis dimidiata, the caviids Cavia aperea and Galea musleloides, the cricetids Akodon azarae, Calomys spec., Cabreramys obscurus, Reithrodon auritus, Oxymycterus rutilans, and the murid Mus musculus. The pellets were collected on the coastal cliff near Miramar in the Province of Buenos Aires in Argentine. A comparison of species composition obtained by trapping revealed some differences to the results from the pellets. In addition, fossil pellets from Pleistocene sediments of the Southeast of Buenos Aires province have been used to infer palaeoclimatological and palaeozoological conditions. It is, therefore, concluded that one should be cautious when inferring climate and zoogeographical conditions from pleistocene fossil pellets.In a sample of 91 pellets of the Barn Owl Tyto alba a total of 232 small mammals could be identified.
