*Acoustic Parameters of Guiana Dolphin (Sotalia guianensis) whistles in the
Southern Gulf of Venezuela*


The Guiana dolphin, *Sotalia guianensis*, is widely distributed along the
coasts of Central and South America. Similar to other delphinids, this
species emits echolocation clicks, burst pulses, and whistles. Although
whistling seems to play a major role in the social organisation of
dolphins, there is a lack of knowledge about Guiana dolphin whistles
outside of populations in Brazil and Costa Rica. In this study, we describe
the acoustic structure of Guiana dolphin whistles from the southern Gulf of
Venezuela for the first time. We recorded the whistles using an
omnidirectional hydrophone (CR1). For each whistle, we measured maximum
frequency (kHz), minimum frequency (kHz), starting frequency (kHz), ending
frequency (kHz), duration (s), and number of inflection points, using
spectrograms created in SpectraLAB 4.32 software (v. 17). Whistles
presented an average starting frequency of 10.58 kHz (SD=2.49 kHz), a mean
ending frequency of 13.96 kHz (SD=2.60 kHz), an average minimum frequency
of 10.31 kHz (SD=2.33 kHz), a mean maximum frequency of 13.96 kHz (SD=2.51
kHz), an average duration of 0.27 s (SD=0.14 s), and a maximum of 4
inflection points (mode 0). This research provides new insights into the
acoustic behaviour of the Guiana dolphin in the Gulf of Venezuela.
