Quantitative analysis of tonal calls from five odontocete species, examining interspecific and intraspecific variation
Abstract Whistle vocalizations of five odontocete cetaceans, the false killer whale P. crassidens , short‐finned pilot whale G. macrorhynchus , long‐finned pilot whale G. melas , white‐beaked dolphin L. albirostris and Risso's dolphin G. griseus , were analysed and summarized quantitatively. Re...

The within‐location component includes such factors as social context, behaviour and group composition. This component is of a similar magnitude to the between‐species component, indicating that whistles vary considerably with these factors. Significant between‐location differences may be attributable to these confounding factors. For whistle duration, most of the variation occurred within location.
