  ABSTRACT
  A study during autumn and winter in Monte Serra area (Mount Etna) was performed on the pellets of a roost of long-eared owl, Asio otus (Linnaeus, 1758) (Strigiformes Strigidae). Besides, in order to better understand the feeding habits of this species on Mount Etna, the data from Monte Serra were integrated with those from Linguaglossa Pineta (breeding period). The study was performed through the analysis of 1,724 preys. The species most preyed was the Mammalia Microtidae Microtus savii (de Selys-Longchamps, 1838). The average weight of the preys was 23.48 g, while the average meal was 36.63 g. Besides, the results of the yearly monitoring of the roost studied are given.
