Abstract

The present study evaluates variations in frequency and duration parameters of whistles of four dolphin species (, , , and ), recorded in the Rio de Janeiro State Coast, Southeastern Brazil. A total of 487 whistles were analyzed. Acoustic parameters of the whistles were classified to species by discriminant function analysis. Overall classification score was 72.5%, with the highest classification score obtained for whistles of and the lowest obtained for . Most differences were among and , species that did not have their repertoires compared in other studies.
