What are the orca migration patterns like in the Pacific Ocean?

Orca migration patterns in the Pacific Ocean are typically influenced by the availability of food sources, such as salmon, and the need to breed and give birth in warmer waters. They can travel long distances along the coast, from Alaska to California, following these food sources and seasonal changes. Some orcas also migrate between different regions within the Pacific Ocean, such as between the waters off the coast of North America and those near Japan.
