Orca Behavior Institute Inspiring conservation of wild killer whales through non-invasive research, bold advocacy, and science-based education.

The Orca Behavior Institute is a non-profit whale research organization based on San Juan Island, Washington. Founded in 2015, OBI was created by a small group of passionate community scientists. Our goal is to establish long-term data sets documenting changes in whale behavior in the Salish Sea to inform protection of Bigg’s killer whales and recovery of Southern Resident killer whales. By tracking and confirming whale sightings throughout the region, conducting field observations of whale behavior, and recording and analyzing whale acoustic communication, we aim to publish current data and trends in a timely manner to inform other research efforts and on-going policy decisions. As we’ve grown in recent years, our work has expanded to include science-based continuing education programs and partnerships aimed towards promoting bold advocacy on behalf of regional killer whales and the ecosystem they rely on.

Some days, you just run out of superlatives. Such was the case yesterday when conditions allowed us to go west - way west - on our second of two all day trips with Maya's Legacy Whale Watching for our Fluking Around with Humpbacks class.

Southeast of Sombrio in the Strait of Juan de Fuca, about 20 miles from the open Pacific Ocean, we encountered what local naturalists refer to as "the herd" - a huge congregation of humpback whales that forms here in the early fall to feed prior to migrating to their respective breeding grounds. We estimated there were at least 300 humpback whales within 5 miles of us, but it becomes impossible to count when you can see a wall of blows in every direction. One student looked through binoculars in one direction for 30 seconds and counted 16 whales just within her field of view.

Another student had a wish to see BCZ0366 Caspian, a particularly unique looking whale with unusual patterning on his body and one of the more unusual looking flukes. Amazingly, shortly before departing, we found him: the whale in this photograph. You might not think of an animal weighing over 50,000 pounds as being hard to find, but it very much felt like finding a needle in a haystack!

Jason will be putting together a video of the experience that we will share as well. We ended the day with a feeling of pure gratitude that such incredible sights are out there to be seen anywhere, let alone right here in the Salish Sea.

Got to meet the newest member of the T36A1s today! This little one, who has received the designation T36A1B from Bay Cetology, was first documented on September 26th and appears to be a few weeks old.

TGIF! Here's hoping your weekend brings you moments like this one 🤩

This photo was taken last Sunday as T19C Spouter and T65A3 Amir rounded the north end of Henry Island. With lots of orcas around this week and some awesome early autumn weather in the forecast, we can't wait to see what this weekend has in store!

Earlier this month, the House Natural Resources Committee approved HR 9621, the "Northwest Endangered Salmon Predation Prevention Act of 2026", which would allow for additional exemptions under the Marine Mammal Protection Act broadening where, when, and how pinnipeds could be lethally removed in the name of protecting listed salmon stocks.

Christopher Dunagan's latest article goes into this issue in depth. It's a long read, but well worth it to learn about all sides of this controversial topic.

A proposed amendment to the Marine Mammal Protection Act has renewed a debate over the merits of killing seals and sea lions to protect salmon. Proponents say it will help some endangered salmon populations while opponents say the legislation is misguided and likely to be counterproductive.

Two bulls on Saturday (T49A2 and T49C), and two different bulls on Sunday!

We were lucky enough yesterday to catch up with the T19s in Spieden Channel, and T65A3 Amir was traveling with them. The group was split into pairs and it was fun to see 19 year-old T65A3 traveling in close association with 25 year-old T19C Spouter for the duration of our encounter.

Male-male social associations are common across both ecotypes of killer whale, and always fun to watch, not to mention impressive when you see two towering dorsal fins surfacing side by side.

Of all the dynamic duos we see, this one may very well be my favorite: T49A2 Jude and his uncle T49C Neilson. This is the fifth year in a row we've documented them meeting up in the San Juan Islands, always either in March/April or September/October.

Today, however, was not a good afternoon to be a seal on the east side of Orcas Island. At a minimum, we think they took four seals over the course of 50 minutes! 😳 They had a clear strategy in play and it worked for them again and again. It was impressive to watch!
