Previous studies indicate that the southward migration through Oregon lasts about two months (Herzing and Mate 1984). However, 90% of the whales migrated past Yaquina Head between December 19 and January 23. The northward migration through Oregon is divided in two phases. Phase A, which comprises adults without calves, begins during the last week of February with a peak in mid-March.
Because of their long visits, the whales have been nicknamed âresidentâ gray whales, the Pacific Whale Watch Association said. About 22,000 gray whales make an annual migration from California to Alaska, and many of them visit Washington state waters to feed. Thereâs a subgroup within the migration, about 200 of them, which make up a Pacific Coast feeding group. They donât go to Alaska and rather stay in the Pacific Northwest, Calambokidis said.
