“…However, as noted earlier, such visitations occurred even when no other dolphin was present at the visited raft. Furthermore, we did not find correlations for dolphins' known social structure (e.g., interactions or status; see Perelberg & Schuster, 2008) regarding destination of visitation.…”

“…Unlike many delphinids (dolphins: Connor, Smolker, & Bejder, 2006;Fellner, Bauer, Stamper, Losch, & Dahood, 2013;Hill & Lackups, 2010;Mann & Smuts, 1999;Perelberg & Schuster, 2008;killer whales: Ray, Carlson, Carlson, Carlson, & Upson, 1986;Ljungblad & Moore, 1983), adult belugas in human care rarely swim together (H. Hill, personal observations). Thus, observations of pair swims between adult belugas or between two males suggest that these swims might be purposeful and functional (e.g., increased opportunity for mating or bond formation such as in some bottlenose dolphins, Dudzinski et al, 2009).…”

-The repertoire of socio-sexual and sexual behaviors of cetaceans is relatively unknown. The purpose of the current study was to advance the existing knowledge of socio-sexual behavior of beluga whales through the development of a behavioral catalog that lists the full repertoire of sexual and socio-sexual behaviors. A behavioral catalog was developed initially from 800 hours of observations, collected across a 7-year period from 11 belugas ranging in age (birth to 30+ years), sex, and social groupings. Using this behavioral catalog, observations of eight additional belugas housed between two other facilities were coded for socio-sexual and sexual behaviors. Sociosexual and sexual behaviors of belugas were similar across all three facilities. Socio-sexual and sexual behaviors involved sequenced behaviors, had lateralized components, and were often subtle in nature. Some of these behaviors overlapped with potentially aggressive actions but showed distinct differences in their form, or topography. Complexity and duration of socio-sexual interactions varied depending on the age and sex of the participating belugas. The development of a complete behavioral catalog, or ethogram, of the socio-sexual and sexual behaviors has profound influences on understanding the mechanisms involved for successful reproduction, a problem that several groups of belugas in their natural habitat are currently facing.Keywords -Beluga, Socio-sexual behavior, Sexual behavior, Behavioral repertoire, Delphinapterus leucas Socio-sexual behavior has been studied in terms of reproductive success, copulation, and courtship. Reproductive success and copulation rates are relatively easy to identify if the definition includes documenting pregnancies, births, and intromission attempts between sexually-mature and receptive individuals. These behaviors, which are directly related to conception or involve direct stimulation of genitalia, can be defined with the term sexual (Campbell, 2007;Connor, Read, & Wrangham, 2000;Connor, Wells, Mann, & Read, 2000). In comparison, socio-sexual behavior includes behaviors that may not be directly involved in conception but may be used for other social purposes, such as developing and maintaining relationships between individuals or courtship (Campbell, 2007;Connor, Wells, et al., 2000). Courtship has traditionally been defined as the innate set of behaviors performed prior to copulation (Lorenz, 1958;Tinbergen, 1952). More recently, the definition of courtship has been expanded to include both elicited innate and emitted learned stereotyped behaviors that draw the attention of potential mates (reviewed by Freeberg, 2000). Hill et al. 106A review of general research on animal behavior indicated that sexual and socio-sexual interactions were the least studied area of research (27% of articles reviewed, Hill, Artz, & Lopez, 2014). Most studies of socio-sexual and sexual interactions have been conducted primarily with fish, amphibians, and invertebrates in laboratory settings. The sexual and socio-sexual behav...

“…Furthermore, such active sound production would reveal the locations of all members of the group to prey or competitors, which is likely to be disadvantageous in many situations. Humpback whales, belugas, orcas, and bottlenose dolphins are all known to engage in sophisticated foraging strategies in which multiple animals must coordinate their underwater movements in three-dimensions to corral prey (Connor, 2000;Wiley et al, 2011), and they often synchronize their movements within groups (Fellner, Bauer, & Harley, 2006;Perelberg & Schuster, 2008). Coordinating invisible movements in the ocean can be a highly challenging task.…”

Vocal imitation is often described as a specialized form of learning that facilitates social communication and that involves less cognitively sophisticated mechanisms than more "perceptually opaque" types of imitation. Here, we present an alternative perspective. Considering current evidence from adult mammals, we note that vocal imitation often does not lead to learning and can involve a wide range of cognitive processes. We further suggest that sound imitation capacities may have evolved in certain mammals, such as cetaceans and humans, to enhance both the perception of ongoing actions and the prediction of future events, rather than to facilitate mate attraction or the formation of social bonds. The ability of adults to voluntarily imitate sounds is better described as a cognitive skill than as a communicative learning mechanism. Sound imitation abilities are gradually acquired through practice and require the coordination of multiple perceptual-motor and cognitive mechanisms for representing and generating sounds. Understanding these mechanisms is critical to explaining why relatively few mammals are capable of flexibly imitating sounds, and why individuals vary in their ability to imitate sounds. Keywords: mimicry; copying; social learning; singing; emulation; imitatible; convergence; imitativenessIn his seminal text, Habitat and Instinct, Lloyd Morgan (1896, p. 166) describes two general kinds of imitation: instinctive imitation and intelligent or voluntary imitation. The examples he provides of intelligent imitation mostly involve reproducing sounds-a child copies words used by his companions, a mockingbird imitates the songs of 32 other bird species, a jay imitates the neighing of a horse, and so on. In fact, most of the examples of "imitation proper" that Morgan provides consist of birds reproducing the sounds of other species. Similarly, Romanes (1884) focuses almost exclusively on reports of birds imitating songs, music, and speech in his discussion of imitation. These classic portrayals of vocal reproductions as providing the best and clearest examples of imitation stand in stark contrast to current psychological discussions of imitation, which often classify examples such as those given by Romanes and Morgan as non-imitative performances that merely resemble actual imitation (Byrne, 2002;Heyes, 1996). When did phenomena that were once considered archetypal examples of voluntary imitation transform into a footnote of modern cognitive theories? Was some discovery made that fundamentally changed our scientific understanding of the processes underlying vocal imitation? Have psychologists or biologists succeeded in explaining what vocal imitation is and how it works to the point where little can be gained from further study? Or, have theoretical assumptions led scientists to underestimate the cognitive mechanisms required for an individual to be able to flexibly imitate sounds?In the present article, we attempt to identify what exactly vocal imitation entails, and to assess whether current explanatory fr...
