THREE BRIEF NARROW-BAND SOUND EMISSIONS BY A CAPTIVE MALE RISSO'S DOLPHIN, GRAMPUS GRISEUS.
Abstract
Illustrated with a sonagram, three brief sound emissions are described and discussed. The sounds were made by a subadult male while stranded during venipuncture. It is suggested that the emissions are fragmentary or abbreviated whistle contours. The similarity of the three phonations suggests that a 'signature' may be present in the whistle of individuals of this species. The literature on vocalizations by this species is summarized.
