The resident orcas of the Salish Sea are dying. They now number only 75, a 30-year-low. They are being starved as their primary prey, the Chinook, or king salmon, are dying off. They are also being poisoned by pollutants in their waters and hurt by noise pollution from ships and boats. For the last three years, not one calf has been born to the three orca pods in the Salish Sea They have been listed as endangered in both the U.S. and Canada since 2005, but little has been done to reverse their steady decline.
There are three distinct groups of orcas, also known as killer whales, on the coast of the Pacific Northwest. Two groups of orcas referred to as residents, eat almost exclusively fish and return to the same areas immediately along the coast year after year. They are divided into Northern and Southern groups.
