Orca migrate into these northern waters in the fall to feed on herring. Most often they use a feeding strategy in which multiple animals work cooperatively to "corral" the herring into tight schools, then swim through and eat them. But frequently these days, the orca are finding that they can get an easier meal by hanging out near commercial fishing boats and picking up the fish that escape from the nets.
