“…It has been suggested that the protection of calves through alloparental care improves the reproductive success of dolphins [Wells, 2003] and sperm whales [Whitehead, 1996]. Belugas may similarly benefit, considering that their sociality has been deemed comparable to these two species [e.g., Recchia, 1994]. It has also been proposed that the protection of calves through alloparental care is a strong evolutionary influence for social living in female sperm whales [Arnbom and Whitehead, 1989] and may be one of the driving forces for sociality in belugas as well.…”

This study describes allonursing (females nursing offspring that are not their own) in captive belugas (Delphinapterus leucas). In addition to the calf's mother, two females that were not pregnant or nursing at the time of the calf's birth spontaneously lactated and nursed the male calf intermittently throughout 34 months of his life at the Vancouver Aquarium Marine Science Center. These observations suggest that allonursing may also take place in their wild counterparts and add to existing evidence of alloparental care in this species. Alloparental care, the care of nonoffspring, has been observed in every major mammalian taxon; the protection of calves through alloparental care may be a strong evolutionary benefit.

“…Whistles were the most common calls, comprising about two-thirds of the sample. Recchia (1994) conducted a systematic quantitative analysis and categorization of the vocal repertoire of captive beluga whales. She found a much lower proportion of tonal signals, about 20%.…”

“…Amongst the toothed whales, perhaps the best documented communication system is that of the beluga Delphinapterus leucas, in which 80% of calls may be pulsive ͑Sjare and Smith, 1986;Recchia, 1994͒. Click-based repertoires from two other odontocete species have also been documented: the Hector's dolphin Cephalorhyncus hectori ͑Daw-son and Thorpe, 1990͒ and the sperm whale Physeter macrocephalus ͑Gordon, 1987͒.…”

Quantifying the acoustic repertoire of a population: The vocalizations of free-ranging bottlenose dolphins in Fiordland, New Zealand

Quantification of the vocal repertoire of a species is critical for subsequent analysis of signal functionality, geographical variation, social relevance, and transmission. While signal repertoires have been documented for numerous animal species, detailed descriptions for the cetaceans are rare. This study describes the vocalizations of free-ranging bottlenose dolphins resident to the waters of Fiordland, New Zealand. The field recordings presented in this paper were made using both audio band and broadband apparatus. Subsequent classification of vocalizations using multivariate parameters enabled a quantification of the entire vocal output of the focal animals. These results were used to propose a meaningful repertoire of signals employed by this species. A total of 12 individual signal types were described, comprising four broad structural classes: "tonal," "single bursts," "click bursts," and "repeat bursts." The proposed repertoire will allow subsequent investigation into vocal behavior. It appears that the successful description of a species' repertoire is dependent on the use of appropriate recording systems, a high number of representative recordings with good signal-to-noise ratio, and subsequent validation of the original classification system.
