A Group Of Gray Whales Survives Die-Off With An Annual Detour To Puget Sound | Northwest Public Broadcasting
Scientists are now monitoring what they call an unusual mortality event that’s been reducing their population again. But, a small group is surviving the die-off by taking an annual detour into Puget Sound. Researches call this group the Sounders.
Normally, gray whales wait till they get to the Arctic to eat. They feed on tiny crustaceans, all summer long. But for about 30 years now, researchers have observed this small group in North Puget Sound every spring, feeding on ghost shrimp that burrow beneath the sand. The Sounders are made up of a core group of about 12 known individuals.
