Bigg’s orca whale sightings are up in Northwest WA. Here’s what we know

Bigg’s killer whales differ from southern resident orcas in that they prey on other marine mammals such as seals and whales, rather than salmon or other marine fish.

“It’s one of those good news stories,” Salish Sea Institute Associate Director Dr. Cindy Elliser told The Herald. “They’re here because there is food. This shows that if we can protect the prey, predators will come. Seeing them is a good sign that things are going well in the ecosystem.”
