Northern resident orcas information


Northern resident orcas, also known as northern resident killer whales (NRKW), are one of four separate, non-interbreeding communities of the exclusively fish-eating ecotype of orca in the northeast portion of the North Pacific Ocean. They live primarily off the coast of British Columbia (BC), Canada, and also travel to southeastern Alaska and northern Washington state in the United States. The northern resident population consists of three clans (A, G, R) that consists of several pods with one or more matrilines within each pod. The northern residents are genetically distinct from the southern resident orcas and their calls are also quite distinct.[1]
