The waters of the Salish Sea are home to two distinct populations of killer whales: the Southern Resident killer whales and the Bigg’s killer whales. Though they share the same waters, these two populations differ dramatically in diet, social structure, vocalizations, and hunting strategies—making them some of the most specialized orca populations in the world.
In this illustrated talk, we’ll explore what sets these two groups apart, as well as what makes each population globally unique. Topics include family structures and matrilines, communication and echolocation, prey preferences, and how cultural knowledge is passed between generations of whales.
We’ll also examine current population numbers, conservation successes, and the ongoing threats facing orcas in the Salish Sea—from prey availability and vessel disturbance to toxins and climate-driven ecosystem change. The program concludes with a discussion of how individuals and communities can take meaningful action to support orca recovery and stewardship of the waters we share.
This program is ideal for anyone who wants a deeper, science-based understanding of orcas—and a clearer picture of how human choices shape their future.
If you can't make the specific date or time of a class you want to take, you can still register and we will send you a link to view the program on your own time! All registrants will have access to the class recording for a limited time to re-watch too.
