Limited previous evidence suggests that killer whales (Orcinus orca) are capable of vocal production learning. However, vocal contextual learning has not been studied, nor the factors promoting learning. Vocalizations were collected from three killer whales with a history of exposure to bottlenose dolphins (Tursiops truncatus) and compared with data from seven killer whales held with conspecifics and nine bottlenose dolphins. The three whales' repertoires were distinguishable by a higher…

Vocal repertoires of two matrilineal social whale species Long-finned Pilot whales (Globicephala melas) & Killer whales (Orcinus orca) in northern Norway

This thesis describes a vocal repertoire subset from seven groups of pilot whales and 11 groups of killer whales recorded in the Vestfjord in northern Norway during the time period 2004 until 2011 and finds that vocal repertoire size depends on the length of recording time and of a group’s vocal activity.

The many functions of vocal learning

The diverse usages and proposed functions of learned novel signals are surveyed, to build a framework for considering the evolution of vocal learning capacities that extends beyond sexual selection.

The Social Role of Vocal Complexity in Striped Dolphins

Testing the hypothesis that more complex acoustic pattern plays a key role in social activity in the striped dolphins indicates the pivotal role of vocal complexity during social context and elicit further investigations of the communication system of small odontocetes from local to wider spatial scale.

Elephants and Sirenians: A Comparative Review across Related Taxa in Regard to Learned Vocal Behavior

This review covers the most important acoustic aspects related to vocal learning in elephants, manatees, and dugongs, as well as knowledge gaps that must be filled for one to fully comprehend why vocal learning evolved (or did not) in these distinctive but phylogenetically related taxa.

Perspectives on the Function of Behaviors Synchronized with Calling in Female Killer Whales, Orcinus orca: Patterns of Bubbling and Nodding in Bouts

Author(s): Bowles, Ann E.; Musser, Whitney B.; Denes, Samuel L.; Grebner, Dawn M.; Clark, Kelly Flaherty | Abstract: In odontocetes, synchronous visible displays accompany a small proportion of…

Vocal production learning in mammals revisited

The available evidence for vocal learning in mammals from the last 25 years is summarized, updating earlier reviews on the subject and highlighting the importance of quantitative comparisons of seemingly learned sounds with vocal repertoires before learning started or with species repertoires to confirm novelty.

Call types of Bigg’s killer whales (Orcinus orca) in western Alaska: using vocal dialects to assess population structure

Abstract Bigg’s killer whales (Orcinus orca; i.e. ‘transient’ ecotype), as apex predators, are important to the dynamics of marine ecosystems, but little is known about their population structure in…

I beg your pardon? Acoustic behaviour of a wild solitary common dolphin who interacts with harbour porpoises

ABSTRACT Kylie is a solitary common dolphin who inhabits a restricted area within the Firth of Clyde (Scotland). She spends most of her time around navigational buoys in the Hunterston/Fairlie…

Contingent parental responses are naturally associated with zebra finch song learning

Acoustic differentiation of Shiho- and Naisa-type short-finned pilot whales in the Pacific Ocean.

Call analyses indicate that the Naisa and Shiho types of short-finned pilot whales are acoustically distinct, which supports the hypothesis that the two types may be separate sub-species, and improves the understanding of their distribution in areas where genetic samples are difficult to obtain.

Whistle sequences in wild killer whales (Orcinus orca).

It is concluded that whistle sequences in wild killer whales are complex signal series and proposed that they are most likely emitted by single individuals.

Horizontal transmission of vocal traditions in killer whale (Orcinus orca) dialects

The results suggest that the real picture of the distribution of call features and call types in killer whales dialects contradicts the classical hypothesis of killer whale dialect evolution through the accumulation of copying errors.

Call sharing across vocal clans of killer whales: Evidence for vocal imitation?

It is shown that call sharing across vocal clans occurs in orcas but is rare and that shared calls are structurally distinguishable from original call types in the absence of the groups originally producing the calls.

Call-type matching in vocal exchanges of free-ranging resident killer whales, Orcinus orca

The structure of stereotyped calls reflects kinship and social affiliation in resident killer whales (Orcinus orca)

The results show that call structure reflects relatedness and social affiliation, but not because related groups spend more time together, and support the hypothesis that increasing social complexity plays a role in the evolution of learned vocalisations in some mammalian species.

Evidence for vocal learning in juvenile male killer whales, Orcinus orca, from an adventitious cross-socializing experiment

Evidence is provided that juvenile male killer whales are capable of learning new call types, possibly stimulated by a change in social association.

Captive dolphins, Tursiops truncatus, develop signature whistles that match acoustic features of human-made model sounds.

It is suggested that captive-born dolphins can incorporate features of artificial acoustic models made by humans into their signature whistles.

The data show that signature whistle exchanges are a significant part of a greeting sequence that allows dolphins to identify conspecifics when encountering them in the wild.

Vocal traditions among resident killer whales (Orcinus orca) in coastal waters of British Columbia

Underwater vocalizations were recorded during repeated encounters with 16 pods, or stable kin groups, of resident killer whales off the coast of British Columbia, finding that individuals appear to acquire their pod's call repertoire by learning, and repertoires can persist with little change for over 25 years.

Bottlenose dolphin (Tursiops truncatus) calves appear to model their signature whistles on the signature whistles of community members

The results suggest that calves may model their signature whistle on the signature whistles of members of their community, possibly community members with whom they associate only rarely.
