Southern resident killer whales, a critically endangered population that frequents the Puget Sound during the summer and fall, have a more varied diet.
Southern Resident killer whales, a critically endangered population that frequents the Puget Sound during the summer and fall, have a more varied diet than previously believed, according to new research.
While Chinook, chum, and coho salmon are the primary food sources for these whales, researchers have discovered that their diet extends beyond these fish."Outside the summer months, and maybe when they aren’t in the San Juan Islands, they actually eat a lot of things that are not Chinook salmon, which is a cool new finding," Van Cise said.
Van Cise noted, "We don’t have a good sense whether that has always been the way that they forage or if it’s some kind of a new response to the lack of Chinook in the area."
