During a study of territorial behaviour of the Pygmy Owl in NE Italy we used spectrographic analyses of recorded territorial calls to distinguish individual males. Two temporal parameters and the mean fundamental frequency of the song were selected and measured. All parameters of calls varied significantly within the population and discriminant analysis correctly classified 84.6% of the individual Pygmy Owls. Most individuals differed from each other with respect to the three selected parameters.

Abstract
During a study of territorial behaviour of the Pygmy Owl in NE Italy we used spectrographic analyses of recorded territorial calls to distinguish individual males. Two temporal parameters and the mean fundamental frequency of the song were selected and measured. All parameters of calls varied significantly within the population and discriminant analysis correctly classified 84.6% of the individual Pygmy Owls. Most individuals differed from each other with respect to the three selected parameters.File in questo prodotto:
