Abstract
Abstract This study investigates the frequency, temporal and power parameters in 11 (5 males, 6 females) captive feral domestic cats Felis silvestris catus , vocalising in their individual outdoor enclosures during the mating season. Discriminant function analysis (DFA) classified the meows to correct callers with 79.2% accuracy, which exceeded the chance level of 22.9 ± 2.8%, calculated with permutation test. Male meows were lower-frequency, with the maximum fundamental frequency of 0.37 ± 0.05 kHz vs 0.61 ± 0.16 kHz in females. Sex differences in the maximum, beginning and end fundamental frequencies varied from 32 to 39%, depending on acoustic parameter. The DFA classified the meows to correct sex with accuracy of 88.0%, which exceeded the chance level of 58.2 ± 3.1%. We discuss that the meows encode information about individual identity and sex and that acoustic differences in frequency parameters of the meows exceed sexual dimorphism of body size in domestic cat.
期刊介绍：
Behaviour is interested in all aspects of animal (including human) behaviour, from ecology and physiology to learning, cognition, and neuroscience. Evolutionary approaches, which concern themselves with the advantages of behaviour or capacities for the organism and its reproduction, receive much attention both at a theoretical level and as it relates to specific behavior.
