Killer whales swimming near The Rock

Some 50 killer whales moved into Central Puget Sound on Wednesday night, and on Thursday they were seen at various locations from Vashon Island to Bainbridge Island, according to Susan Berta of Orca Network.

The orcas included J and K pods as well as a few whales from L Pod, she said.

The three killer whale pods, known as Southern Residents, often visit Central and South Puget Sound in the fall and early winter, when they feed on chum salmon returning to streams in the region.

Researchers confirmed that the whales were feeding, Berta said, because at least one was spotted with a fish in its mouth.

In other local killer whale-related news, the Bainbridge Historical Museum is showing the exhibit “Whales in Our Midst: Killer Whales in the Salish Sea” through the fall.
