Abstracts. – Annotated bibliography on raptor pellets analyses in Argentina. – We compiled an annotated bibliography on raptor pellets analyses in Argentina. It includes, from 1961 to 2000, 142 papers, 9 theses, and 48 published abstracts concerning 13 raptor species, with comments on methodology, natural history, and main points of interest. Tyto alba was the main source for Argentinean analyses, with 111 studies, followed by Athene cunicularia (30), Bubo virginianus (26), and Asio flammeus (14). More than 70% of the diets of 19 species of owls known in the country, have not been analyzed. A comparison with similar studies conducted in Chile was made, based on the synthesis of Jaksic (1996). In Argentina, the contributions give an emphasis on the raptor prey species (mainly small mammals), taxonomy, and geographic distribution, with few papers dealing with the trophic ecology of the predators. On the opposite, Chilean works were more related with applied and theoretical aspects of the predator-prey relationship.We compiled an annotated bibliography on raptor pellets analyses in Argentina.
