Abstract:
For one year, starting on September 5th 1994, the behaviour of a captive new-born bottlenose dolphin Tursiops truncatus and its mother was monitored through both video and acoustic recordings. The main objective of such research was to study the behavioural evolution of the two during the first year of the calf's life. Attention was focused on acoustic behaviour and its use in relation to the contexts. In order to be able to discover any possible correlation, the acoustic signals were analysed with a Pc-based DSP Workstation developed at the University of Pavia, and the resulting real-time spectrographic analyses were superimposed on the live video recordings.
