Indication that the behavioural responses of humpback whales to killer whale sounds are influenced by trophic relationships
TLDR
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.
Orchestration: The Movement and Vocal Behavior of Free-Ranging Norwegian Killer Whales (Orcinus Orca)
TLDR
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
TLDR
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.
Vocal activity of tropical dolphins is inhibited by the presence of killer whales, Orcinus orca
TLDR
Despite the relative rarity of killer whales in the tropics, they appear to influence vocal behavior of nearby dolphin schools, and this disruption in communication may not significantly impact interactions necessary for survival in tropical waters where killer whale density is low, but in temperate climates, where increased productivity supports a greater abundance of Killer whales, this interruption in communication might have a greater impact.
Killer whale presence drives bowhead whale selection for sea ice in Arctic seascapes of fear
TLDR
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
TLDR
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
TLDR
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.
Predation on gray whales and prolonged feeding on submerged carcasses by transient killer whales at Unimak Island, Alaska
TLDR
A 4 yr time series of foraging and feeding behavior of >150 transient killer whales that aggregate annually during the northbound migration of gray whales past Unimak Island, Alaska finds that most predatory attacks were on gray whale Eschrichtius robustus calves or yearlings and were quickly abandoned if calves were aggressively defended by their mothers.
Ecotypic variation and predatory behavior among killer whales (Orcinus orca) off the eastern Aleutian Islands, Alaska
TLDR
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
TLDR
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.

Acoustic behaviour of resident killer whales (Orcinus orca) off Vancouver Island, British Columbia
TLDR
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
TLDR
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
TLDR
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.
On the communicative significance of whistles in wild killer whales (Orcinus orca)
TLDR
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
TLDR
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
TLDR
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.
Call-type matching in vocal exchanges of free-ranging resident killer whales, Orcinus orca
Predation as a cost of sexual communication in nocturnal seabirds: an experimental approach using acoustic signals
TLDR
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
TLDR
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.
Vocal traditions among resident killer whales (Orcinus orca) in coastal waters of British Columbia
TLDR
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.
