  1. Dear Mr. Dunagan,

    In regards to the Southern Residents preference of Chinook salmon, it’s not “cultural”, it’s biological. They have evolved over 10,000,000 years to eat fish. Chinook are preferred because of the many types of salmon here they A) are the fattiest, and B) until relatively recently, they were abundant. The Southern Residents (and Northern Residents too) have an entire physiology,teeth, gastric juices, bone structure, etc. designed for fish. That’s not culture, that’s biology.

    1. Jane,

      Thanks for commenting. It is true that the resident whales have evolved to digest fish, but their preference for chinook and methods to hunt them is learned behavior. I think the authors of the paper raise some very interesting issues.
