Temporal and Contextual Patterns of Killer Whale ( Orcinus orca) Call Type Production
Abstract Fish‐eating killer whales Orcinus orca in the northeastern Pacific live in highly stable matrifocal social groups called pods. Each pod produces a repertoire of seven or more stereotyped call types. We compared the relative production of call types of free‐ranging killer whale pods over tim...
