Transient orca populations are healthy. Because of the federal ban on marine mammal hunting since 1972, transients are feasting on seals and other plentiful marine mammals, including Pacific white-sided dolphins and even gray whale calves. Transient orcas will team up to take down a really big target, such as a sea lion. They will often hunt close to shore, since that is where their prey is found, lounging on rocks.
Unlike the transient orcas, southern resident orca whales, the salmon-eating whales that frequent Puget Sound, are fighting extinction. Southern resident orcas face a combination of threats, including pollution, boat and ship noise and disturbance that makes it harder for them to hunt, and lack of chinook salmon, their preferred prey.
Tl’uk’s family is rarely seen in local waters. Usually the family is seen north of the San Juan Islands. But beginning in April, the whales made their first documented trip down to Admiralty Inlet, spending four days in Saratoga Passage between Penn Cove and Holmes Harbor. Then the family was seen in the deep south of Puget Sound, in Case and Henderson Inlets, Garrett said.
The gray whale is less than 2 years old. He is only the second such whale known to have been seen in the Salish Sea, the transboundary waters between the U.S. and Canada, including Puget Sound. The first was Chimo, a whale captured back when hunts were still allowed on orca whales to supply the aquarium trade.
“It is great to see that guy, just amazing,” Garrett said of Tl’uk, who does appear white in the dark green of the water. “There is a certain mystical quality.”
