Call type repertoire of killer whales ( Orcinus orca ) in Iceland and its variation across regions
Abstract Killer whales ( Orcinus orca ) have group‐specific call repertoires that can be used to track groups and populations using passive acoustic monitoring. To provide a detailed description of the Icelandic killer whale repertoire and its variation, we analyzed acoustic data collected in five l...
