TL;DR: 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.

TL;DR: 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...

TL;DR: Foraging by resident killer whales was found to frequently involve sharing by 2 or more whales, and strong selectivity for chinook salmon by resident Killer whales probably has a significant influence on foraging tactics and seasonal movements, and may have important implications for the conservation and management of both predator and prey.

TL;DR: In this article, the patterns of echolocation sounds produced by killer whales, Orcinus orca,o V British Columbia and Alaska are described, and two sympatric populations with divergent food habits diVered markedly in sonar sound production.
