Volunteer researchers led by Monika Wieland Shields of the Orca Behavior Institute in Friday Harbor, Washington, estimated transient orcas consumed 1,090 seals in the Salish Sea in 2017 — or more than 2 percent of an estimated harbor seal population of 51,000 in Puget Sound. The study, published in Marine Mammal Science, was funded by the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Fish and Wildlife Service (USFWS).
