Acoustics and Social Behavior of Wild Dolphins: Implications for a Sound Society

Variation in the emission rate of sounds in a captive group of false killer whales Pseudorca crassidens during feedings: possible food anticipatory vocal activity?

“…Moreover, Ridgway et al (2014) suggested that burst pulses produced during feeding sessions might be considered as food calls with emotional content. Nevertheless, more substantial experiments involving the diff erent aspects of food delivery should be carried out (food quantity and quality, hunger levels, and interaction with the keepers) (Dittus, 1984;Caine at al., 1995;Di Bitetti, 2005;Slocombe and Zuberbühler, 2006;Clay and Zuberbühler, 2009) to assess the presence of a referential content in the calls of dolphins ( Ralston and Herman, 1989 ;Herzing, 2000;Akiyama and Ohta, 2007;Therrien et al, 2012). For example, a behavioral sequence analysis would help to defi ne the function of the vocalizations in relation to the reaction of the conspecifi cs to the phonating individuals (Slooten, 1994).…”

Behavioral event occurrence differs between behavioral states in Sotalia guianensis (Cetarctiodactyla: Delphinidae) dolphins: a multivariate approach

“…In the Socio-sexual state, Lobtails can be used in agonistic interactions, especially male-female ones. Lobtails are used in a non-vocal communicative fashion by Stenella frontalis (Cuvier, 1829) in the Bahamas (HERZING 2000). These actions are used particularly to gain the attention of other dolphins, which will observe the direction that the animal is heading.…”

Social Behaviour, Vocalization and Conservation of Narwhals

“…Pulsed sounds (clicks) are believed to be used, as in other toothed whales, for spatial orientation and echolocation of prey (Au, 1993). Narwhals also produce frequencymodulated whistles and burst-pulsed sounds, which are associated with social communication in other cetaceans (Herzing, 2000). It was suggested that whistles in narwhals might be a form of individual or group signature (Shapiro, 2006).…”
