Humpback Whales. Humpback whales also migrate off the coast of Washington and Oregon and are sighted regularly. Sightings of humpback whales have been increasing in inland waters of Washington State. Humpback whales are cataloged and photographically identified by Cascadia Research Collective. Recent studies of humpback whales in the entire North Pacific conducted under the Structure of Populations, Levels of Abundance, and Status of Humpbacks (SPLASH) project have revealed a complex population structure and growth of overall abundance at 4–7% per year and through 2006, numbered about 20,000 (Calambokidis et al. 2008). Special considerations should be made for humpback whales as they are listed as endangered under the ESA.
