Orcas in Humboldt Bay: Meet Lester and Her Family (T035A) — First California Sighting (2026)

Hold onto your hats, nature enthusiasts! A family of killer whales just paid a rare visit to Humboldt Bay, and their story is as fascinating as it is unexpected. Among them was a 27-year-old matriarch named 'Lester,' a name that might sound more fitting for a human than a whale—but here’s where it gets even more intriguing: Lester is a female, and she brought her entire brood along for the journey. Yes, you read that right—Lester, Opal, Topaz, Garnet, and Agate are all part of the T035A group of Bigg’s Killer Whales, a transient orca family known for their nomadic lifestyle. But here’s where it gets controversial: why are these whales venturing into waters where they’ve rarely been documented before?

Local naturalist Rob Fowler shared insights from Alisa Schulman-Janiger of the California Killer Whale Project, who identified the family by their distinctive dorsal fins. Lester’s kids—15-year-old Opal (T035A1), 12-year-old Topaz (T035A2), 7-year-old Garnet (T035A3), and 3-year-old Agate (T035A4)—were all spotted alongside their mother. This marks the first time this particular group has been recorded in California waters, though Lester’s own mother, the 55-year-old Rooby Roo (T035), was seen near Humboldt Bay back in June 2020. And this is the part most people miss: Rooby Roo now travels with a different group, the T038 squad, raising questions about how and why these family dynamics shift over time.

For those eager to dive deeper into the world of Bigg’s Killer Whales, Our Wild Puget Sound offers a fantastic resource (https://www.ourwildpugetsound.com/journal/meet-the-transient-orcas-biggs-killer-whales-of-puget-sound) that breaks down the various 'gangs' of these roaming orcas. It’s a reminder of how much we still have to learn about these majestic creatures and their complex social structures.

But here’s the real question: What’s driving these whales to explore new territories, and what does it mean for their future? Is it a search for food, a response to environmental changes, or simply the natural curiosity of these intelligent beings? Let us know your thoughts in the comments—this is one conversation that’s sure to make waves.
