Vancouver photographer Mark Malleson took this photograph of the Southern Resident killer whale known as J-34, or Doublestuf, breaching while he was in the interior waters of the Salish Sea this spring. It’s a remarkable and frightening photo for orca lovers, because the male orca’s ribs appear to be protruding prominently.

That’s abnormal, especially for a resident killer whale at this time of year, when the orcas are typically well fed after a winter of preying on Chinook salmon. And so Malleson’s photo set off a number of alarm bells in the Northwest whale-watching community as it circulated on social media.

Subsequent photos taken of J-34 and his pod from a scientific drone suggested that, while the whales weren’t particularly plump, their girth was within their normal range. Nonetheless, veteran whale scientist Ken Balcomb is blunt about what he is seeing for the Southern Residents long-term: “These whales are starving,” he says. “There simply aren’t enough salmon out there for them to eat.”

Balcomb and the crew at San Juan Island’s Center for Whale Research have been observing the Southern Residents foraging this winter and spring, and the behavior has been disconcerting: The whales are much more spread out, meaning they are having to forage harder for individual fish. Many of them appear underfed, he says. It’s an especially alarming development following last year’s “baby boom,” in which nine new calves were born into the population, one of whom has apparently already vanished and is presumed dead.
