Transient Orcas Take Out Steller Sea Lion On 4/27/13

4/28/2013

Waking up early to rain and dark, overcast skies after a good stretch of amazing sunny, warm weather was a little undesirable, but I had a feeling something amazing was going to happen. A few minutes later, reports were coming in of groups of Transient orcas all over the place. Luckily, I was working on the "Odyssey", a San Juan Excursions whale watching boat, so I hoped we would be able to catch up with one of the groups.

We departed Friday Harbor, San Juan Island, and headed North to Spieden Island where we found some steller sea lions. A few minutes later we received a report that a group of Transients had been found by a Victoria whale watching boat only few miles away. Transients, unlike Resident orcas, eat marine mammals and this group was attacking a steller sea lion.

Male steller sea lions can reach up to twelve feet long, weigh in at about 2,400 pounds and are the largest sea lions in the world. The transient orcas were going after a sea lion nearly that size so we made our way toward them. I had seen Transient orcas prey on seals before but never a sea lion, which takes much longer and there are bigger tactics used, including: ramming, full body lunging, tail strikes, blowing bubbles in the sea lions face to so it can't see while other orcas attack, belly flopping on the sea lion and more. Soon we were on scene with the Transient orcas.

The group of Transients was made up of three matrilines, with ten animals altogether. They were T036As, T049Bs and the T065As. T036A, T049B and T065A, all adult females, looked like they were teaching their young how to successfully kill a sea lion. The juveniles and calves seemed to dart in to attack the sea lion and then hang back for a while to play and watch the adults.

One of the best parts of this encounter, though it was all exciting, occurred when a year-old calf called T036A2 breached out of the water but found mama spy hopping underneath... HER.. and bounced off. Yes, I said HER, because it looks like T36A2 is a little girl, although she won't be little for long!!

The orcas had already been attacking the sea lion for quite some time before we arrived on scene and we were with them for about thirty minutes. The sea lion was finally killed and eaten about forty minutes after we left.

I had finally seen Transients take out a steller see lion! What will happen next?

We were with them for about thirty minutes but it took the orcas almost three hours to kill the sea lion.

Thanks for posting this. If I can't be there to see the action this is the next best thing. I've seen Stellers get very nervous and bunch up when T's are in the neighborhood. They spyhop like crazy in a tight group, I've seen about two dozen in Admiralty Inlet do that while T's were miles away. I guess you saw what they are worried about.

thank you sooo much. I have a seemingly undeniable draw to transient orca. the most fascinating creatures on the planet, far surpassing humans and our petty issues.
