Synergy Between Behavioural Research on Beluga Whales (Delphinapterus leucas) Conducted in Zoological and Wild Settings

Behavioural observations of captive beluga whales have complemented and extended much of what has been learnt about this species in the wild. Aquarium-based research has provided finer-scale specificity for many topics, including the seasonal breeding pattern that is characteristic of this species, as well as socio-sexual behaviour that appears to be an important part of the behavioural repertoire of this species. One example is a strong propensity for male–male social interactions that begin to develop at an early age. In addition, detailed behavioural milestones in calves have been documented in ways that extend that which have been collected from wild populations. These include swim positions with mother, separations/reunions with mother, and other social interactions, and play. Characteristics of beluga maternal care have also been studied more often in captive settings than in the wild, particularly with respect to details pertaining to nursing behaviour, individual differences in maternal style and allomaternal care. Other topics that have received scientific scrutiny in zoological settings include individual differences and behavioural laterality. Thus, a greater understanding of beluga behavioural biology has the potential to emerge as a consequence of synergy between research conducted in the two settings

Seasonality of Social Behaviour Among Immature Belugas (Delphinapterus leucas) in Managed Care

Belugas ( Delphinapterus leucas ) in managed care have been reported to show seasonal variation in socio-sexual behaviour, hormone levels and respiration rates; however, little is known about the social interactions of wild belugas when they are not in summer, near-shore congregations. To better understand if belugas show seasonal variation in social interactions, this study recorded the behaviour of 10 belugas (five females, five males, ranging from birth to 10 years of age) housed in managed care. Social interactions typically peaked in the summer months but persisted at very low levels during the rest of the year. Sea - sonal variation was most dramatic for socio-sexual behaviour but was generally mirrored in pattern by agonistic and affiliative interactions. Subjects closer to maturity displayed more seasonal variation than younger subjects, and males displayed more seasonal variation compared to females. The peak in social interactions found in this study aligns rather closely with wild belugas’ sum - mer, near-shore congregations, where belugas have increased opportunities for socializing. Although belugas in managed care do not experience a seasonal change in habitat, they do show seasonal changes in social behaviour, which are likely driven by seasonal fluctuations in hormone levels. It is therefore expected that wild beluga populations would show similar behavioural pat - terns if they were observed throughout the remainder of the year. This research has applications for belugas in managed care and may provide a framework for understanding the social behaviour of wild belugas

Workshop Effectiveness on Content Knowledge of Behavioral Observation Techniques for an Applied Animal Behavior Context

Comparative psychology has a long history of investigating topics that promote comparisons across disciplines, constructs, and species. One critical component of comparative analyses is to select the best data collection technique. Unfortunately, these observational skills are not always taught to individuals who need them the most, animal care professionals. To demonstrate the applicability of appropriate data collection techniques to this applied discipline, we conducted a multi-day workshop that provided attendees training and practice with several data collection techniques that could be used to evaluate animal behavior in both spontaneous and enrichment-provided settings. The program included (1) a presentation on different data collection techniques and the types of questions each technique can address, (2) two 20-minute sessions of observation practice at two different facilities, (3) a final summary presentation of the data collected, and (4) pre- and post-surveys conducted immediately before and at the end of the workshop. Out of 177 survey respondents, almost a third reported using behavioral data collection to manage animal behavior prior to the workshop. More than 90% of the respondents had heard of behavioral ethograms and 68% of the respondents had used one previously. Many of the respondents reported familiarity with different observation techniques. Eighty-two individuals completed the majority of the survey with 81% expressing satisfaction with the initial workshop presentation. Respondents completing both surveys showed significant improvement in their knowledge of behavioral data collection techniques. Ultimately, the workshop introduced and clarified behavioral observation techniques and their applications in a variety of contexts. Respondents indicated that they could and would utilize knowledge gained from the workshop at their own facilities

A review of beluga (Delphinapterus leucas) sexual behavior and reproductive physiology leading to conception

This review summarizes the available literature on the knowledge of reproduction in white whales or belugas (Delphinapterus leucas). We discuss reproductive anatomy, physiology, endocrinology, and behavior prior to conception. Following a description of these basic reproductive parameters for each sex, the review describes the mating system of belugas as it is currently understood and summarizes the ontogeny of reproductive behavior and its relationship with hormones. Finally, we highlight gaps that currently exist in our functional understanding of reproductive behavior in belugas. Future research emphasizes the need to understand mate choice in belugas and how it manifests across the lifespan and potentially settings. Specifically, does the quality of belugas’ display behaviors influence reproductive success? Managing wild populations of belugas and caring for belugas in human care both benefit from the knowledge that can be gained from the research topics discussed in this review

Effects of Human-Dolphin Interactions on Tourist Knowledge of and Attitudes Toward Dolphins

Human-wildlife interactions have been shown to positively impact tourist beliefs and actions in relation to wildlife and the environment. The purpose of this study was to explore guest beliefs and perceptions about dolphins and dolphin programs before and after participating in human-dolphin interactions (HDI). We surveyed 142 guests participating in a self-selected HDI located in a natural lagoon facility at The Roatán Institute for Marine Sciences in Sandy Bay Roatán, Honduras. Of the 142 survey respondents, 130 completed the survey fully, and 28 of those 130 also completed a two-week follow-up survey. The results indicated that the guests maintained pre-existing positive attitudes towards dolphins, learned new information, and reported feeling connected with nature following their HDI experiences. The HDI experience format resulted in few differences in participant responses, suggesting that interactive programs maintained existing attitudes while subtly shaping beliefs about human-animal interactions

The influence of background music and narrative setting on anthropomorphic judgements of killer whale (Orcinus orca) emotional states and subsequent donation behavior.

Animal documentary films such as Blackfish, considered nonfiction accounts of reality, nonetheless use rhetorical devices to engage viewers and shape their emotional experience for maximum effect. Such devices can also influence attitudes and alter behavior. In animal documentaries, anthropomorphic impressions of the animals by audiences are key. Using general population samples in the US, three online experiments assessed the influence of background music and narrative setting on how viewers emotionally appraised the emotional state of a killer whale (Orcinus orca) and subsequently donated to causes affiliated with killer whales. While happy music led to perceptions of a happy whale, sad music led to perceptions of a sad whale. mediation analyses showed that these perceptions indirectly influence donation behavior, via beliefs about the killer whale's welfare and wellbeing. Analyses also indicated that the highest donation amounts towards killer whales were elicited from footage depicting a killer whale in the wild, with sad background music. These findings highlight the potential power that animal and nature documentaries have over viewers, which, when combined with human tendencies toward anthropomorphism, can have significant influence on conservation attitudes and behavior

Training the Concept of Innovate in Dolphins (<i>Tursiops truncatus</i>) Is Both Creative and Cognitively Stimulating

Creative or novel behaviors in bottlenose dolphins (Tursiops truncatus) can be indicators of flexible thinking and problem solving. Over 50 years ago, two rough-tooth dolphins demonstrated creative novel behaviors acquired through reinforcement training in human care. Since this novel training, a variety of species have been trained to respond to this conceptual cue. The current study assessed the creativity of 12 bottlenose dolphins (5 females, 7 males) housed at the Roatan Institute for Marine Sciences (RIMS) in Roatan, Honduras. Individual differences were found across four constructs measured for creativity: fluency, flexibility, elaboration, and originality. Variability in performance occurred across test sessions. Animals with less experience with this task performed fewer “innovative” behaviors as compared to more experienced animals. Despite errors, dolphins continued to attempt the task during test sessions, suggesting the concept of “innovate” was intrinsically rewarding and cognitively engaging. This task may be utilized across species to promote the comparative study of innovative or creative behavior as well as to promote cognitive welfare

Cetacean Responses to Violation of Expectation Paradigm in a Free-swim Context

The investigation of individual responses to unexpected stimuli or outcomes provides insights into basic cognitive processes, such as mental representations, emotional states of surprise, and detections of anomalies. Three experiments using a violation of expectation paradigm were conducted with 12 belugas and 17 bottlenose dolphins in managed care to test two classes of stimuli (humans and objects) in manipulated sequences of familiar and unfamiliar humans (Study 1, trainers and strangers), familiar and unfamiliar objects (Study 2, typical enrichment devices and new objects), and finally objects and humans (Study 3). Gaze durations were assessed for each condition in a given study during free-swim contexts. The results supported previous findings that visual stimuli, regardless of class, were stimulating and intriguing for both belugas and bottlenose dolphins. Belugas were more likely to gaze longer at human and object stimuli and tended to gaze longer at unexpected experiences than control or expected experiences. Bottlenose dolphins showed similar trends except when objects were involved. Individual variability was present for both species with some individuals showing stronger patterns of responses for expected experiences than others. After 2 years of intermittent experiments, belugas and bottlenose dolphins in managed care maintained their curiosity about visual stimuli, for which they received no primary reinforcement. Investigating responses to unexpected stimuli with animals in managed care may provide insight into how these animals respond to biologically relevant conditions, such as boat presence, predators, and unfamiliar conspecifics
