Abstract
Pellets of Short-eared Owl Asio flammeus wintering in the grasslands of Rollapadu Wildlife Sanctuary and its vicinity in Andhra Pradesh, India were analysed. Birds constituted the major prey followed by mammals and invertebrates both in terms of percentage of occurrence (82%) and biomass consumed (87%), indicating that the species is an opportunistic feeder, taking prey in proportion to their availability. A total of 13 species contributed to the diet, 276 prey individuals totaling 4,522g in biomass were found.
