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.
They strain huge amounts of food. from the muddy bottoms of the Bering and Chukchi seas. Most. gray whales migrate south in the fall when the Arctic ice pack starts. to form. They swim along the North American coastline to Baja. California, Mexico -- a distance of more than 6,000 miles (9,656 km). In Baja, the whales give birth and mate in the shallow waters of. Laguna Ojo de Libre (Scammonâs Lagoon), Laguna San Ignacio and. Magdalena Bay. After two or three months, the gray whales travel. back up north to the Alaskan Arctic. In the 19th and early 20th centuries, whalers hunted gray whales. to the brink of extinction. After a ban in 1946 on hunting the whales, the population of California gray whales began to recover.
