The developmnent of sound production abilities in bottlenose dolphins
(Tursiops truncatus) is poorly understood. In this paper,
we describe acoustic features of early sounds produced by a newborn.
Initial underwater sounds (produced 24-48 h after birth) consisted
exclusively of burst-pulses. By day five, whistle-like elements
were evident as components of burst-pulse sounds. These data suggest
that dolphins can produce burst-pulse sounds from a very young
age and that the mechanisms dolphins use to produce both whistles
and burst-pulse sounds are closely related.
