Teaming up on salmon hunts, orcas and dolphins in B.C. have developed a strategy that really clicks

In the narrow channels of Johnstone Strait off northeastern Vancouver Island, northern resident killer whales appear to have discovered an unusual foraging strategy: follow the dolphins.

In a rare example of two marine mammal species working together, scientists have documented northern resident killer whales and Pacific white-sided dolphins co-operatively hunting chinook salmon. The sophisticated partnership was revealed through aerial drones and biologgers – specialized suction-cup cameras attached to killer whales that captured underwater video, acoustic and motion data.
