Indication that the behavioural responses of humpback whales to killer whale sounds are influenced by trophic relationships

Results indicate that humpback whales may be able to functionally discriminate between the sounds of different killer whale ecotypes, suggesting that marine mammals could rely on eavesdropping as a primary source of information to make decisions during heterospecific encounters.

Vocal behaviour and feeding ecology of killer whales Orcinus orca around Shetland, UK

The vocal behaviour of seal-hunting groups showed striking parallels to that of Pacific marine mammal specialists and presumably evolved to decrease detection by acoustically sensitive prey and that of Shetland herring-eating killer whales.

Orchestration: The Movement and Vocal Behavior of Free-Ranging Norwegian Killer Whales (Orcinus Orca)

This closer examination of the movements and vocalizations of Norwegian killer whales will inform the understanding of whether and how culture plays a role in achieving population-specific behaviors in this species.

Selective reactions to different killer whale call categories in two delphinid species

Characterization of the anti-predator behavior of two delphinid species using controlled playback of killer whale calls suggests that structural features of the calls convey information about predatory risk.

Killer whale presence drives bowhead whale selection for sea ice in Arctic seascapes of fear

The results strongly suggest the ecological impacts of killer whales as apex predators extend beyond consumptive/density-mediated effects (direct mortality) and unbiased assessment of habitat use and distribution of bowhead whales and many marine species may not be possible without explicitly incorporating spatiotemporal distribution of predation risk.

Vocal repertoire and acoustic behavior of the isolated AT1 killer whale subpopulation in southern Alaska

The repertoire and call-usage patterns of the AT1 tran- sients are consistent with genetic evidence that they are a unique, reproductively and socially isolated subpopulation in danger of extinction.

Predator sound playbacks reveal strong avoidance responses in a fight strategist baleen whale

Experimental evidence is provided that humpback whales can exhibit a strong horizontal avoidance as an initial stage of anti-predator defence, indicating that anti-Predator responses may be more graded and mixed than previously recognized.

Ecotypic variation and predatory behavior among killer whales (Orcinus orca) off the eastern Aleutian Islands, Alaska

The majority of killer whales in the eastern Aleutian Islands are the resident ecotype, which does not consume marine mammals, and steller sea lions did not appear to be a preferred prey or major prey item during spring and summer.

Whistle communication in mammal-eating killer whales (Orcinus orca): further evidence for acoustic divergence between ecotypes

This work investigated the whistling behavior of mammal-eating killer whales, and, based on divergent social structures and social behaviors between residents and transients, predicted to find differences in both whistle usage and whistle parameters, the results show that, like resident Killer whales, transients produce both variable and stereotyped whistles.

Sperm whales reduce foraging effort during exposure to 1-2 kHz sonar and killer whale sounds.

The results demonstrate that similar to predation risk, exposure to sonar can affect functional behaviors, and indicate that increased perception of risk with higher source level or lower frequency may modulate how sperm whales respond to anthropogenic sound.

Acoustic behaviour of resident killer whales (Orcinus orca) off Vancouver Island, British Columbia

Recordings of underwater vocalizations and behavioural observations were collected from 16 photographically identified resident pods of killer whales off Vancouver Island, British Columbia, during 1978–1983 and no call type was correlated exclusively with any behaviour or circumstance that could be identifie...

A review of Killer Whale interactions with other marine mammals: predation to co‐existence

It is concluded that interactions between Killer Whales and marine mammals are complex, involving many different factors that the authors are just beginning to understand.

The mixed blessing of echolocation: differences in sonar use by fish-eating and mammal-eating killer whales

In both populations, echolocation use per individual decreased with increasing group size, suggesting the sharing of information between group members, and no relationships were found between eCholocation activity and water clarity for whales of either population.

Selective habituation shapes acoustic predator recognition in harbour seals

Investigating the response of harbour seals to the underwater calls of different populations of killer whales found that the seals responded strongly to the calls of mammal-eating killer whales and unfamiliar fish- eating killer whales but not to the familiar calls of the local fish-eating population.

On the communicative significance of whistles in wild killer whales (Orcinus orca)

Whistle activities of groups of individually known killer whales were compared quantitatively across behavioural categories and apparently whistles play an important role in the close-range acoustic communication in northern resident killer whales.

Occurrence and behaviour of transient killer whales: seasonal and pod-specific variability, foraging behaviour, and prey handling

Overall use of the area was greatest during that period, and energy intake at that time was significantly greater than at other times of the year, probably because of the high encounter rates and ease of capture of harbour seal pups.

FORAGING STRATEGIES OF SYMPATRIC KILLER WHALE (ORCINUS ORCA) POPULATIONS IN PRINCE WILLIAM SOUND, ALASKA

Differences in the social organization and behavior of the resident and transient killer whales in Prince William Sound are discussed in the light of the dietary differences documented here.

Predation as a cost of sexual communication in nocturnal seabirds: an experimental approach using acoustic signals

It is shown that skuas can use male petrel calls as a cue for prey location and selection, which imposes a major constraint on advertising petrels, and especially on single males which face a trade-off between attracting females and avoiding predation.

Ecological and social determinants of group size in transient killer whales

The typical size of groups consisting only of adult and subadult whales that were engaged primarily in foraging activities confirms that these individuals are found in groups that are consistent with the maximization of energy intake hypothesis.
