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.
Killer whales migrate northward throughout the Bering Strait in the spring as the pack ice retreats. They leave the Beaufort and Chukchi areas in the fall when the ice advances. Killer whales in the Pacific Northwest and Alaska occur in groups of animals called pods. Most pods in Alaska number fewer than 40 animals. The individuals which comprise each pod change very little. Killer whale pods are matrilineal and consist of a female and her offspring of both sexes.
