Transient Orca Encounters 8/9/17 - 8/19/17

8/24/2017

Since my last post, I have had several outstanding encounters with the marine mammal-eating transient orcas. As for the salmon-eating southern resident orcas, they have not visited the area since August 3rd. Their absence screams that there is not enough Chinook/King salmon for them to survive on here.

Fraser River Chinook/King numbers are at a historic record low and that has caused to the southern resident orca attendance to hit a historic record low as well. These orcas used to be here literally almost every day not that long ago. Since April 23rd, 2017 and as of today (August 24th), there have been only 219 Chinook salmon counted up at the Fraser River. That is not enough to support the NOW 77 southern residents, who, as a community, need over 1000 Chinook salmon a day to survive. You can find the daily Fraser River Chinook/King test fishery numbers here.

As days turn into weeks without the residents in, I constantly worry if they are ok and miss them dearly. There is an apparent void with them gone, and all though the transient orcas have helped fill that void a bit, the empty feeling still remains.

Without an abundance of Chinook salmon, the southern residents will struggle to grow as a population, as shown in their abnormally high rates of miscarries and stillborns during times when the Chinook salmon runs are low. Juvenile and adult orcas die off during these times of hardship as well. Though their story is heartbreaking, it must be told or nothing will change. They feel like a second family to many of us on the water and it is necessary to spread awareness so that their population can recover.

Anything that helps improve Chinook runs in the inland waters as well as off the outer coast (salmon habitat restoration, sustainable fishing, polluting less, removing dams, banning Atlantic farmed salmon pens) will in turn help save the southern resident orcas. There is still hope but we must act now. We must not give up. Here are some websites with more information and how to help:

While the southern residents have been away, the marine mammal-eating transient orcas have been in the area nearly every day. I am happy to say that with a large supply of marine mammals, the transient population is growing fast and new calves are being observed each year.

Aboard the Odyssey on August 9th, we were able to see the T18s as they headed up Haro Strait. They were in travel mode and did not make a kill while we were with them. One of the T18 members, T19B, is one of my favorite transient males due to his funky dorsal fin and massive size so it is always great to see him.

On August 12th, we encountered a humpback whale heading down San Juan Channel but soon after, we got a report of transients coming up San Juan Channel. These transients were the T46s and we all held our breath to see what would happen when the humpback and orcas crossed paths. We wondered if the humpback would get spooked or harassed. Nothing happened, at least above water, but it was cool to see them so close to each other. The T46s continued up the San Juan Channel and kindly led us back to our dock in Friday Harbor.

On August 16th, we got to see the T137s as they swam into East Sound at Orcas Island. Once in the sound, the family of four decided it was lunch time and killed multiple harbor seals. After their first kill right after we arrived on scene, they went into travel mode for a bit and T137A (the teenage male) split off and paralleled his family by a few hundred yards. When mom and his two siblings found another seal, they must have called him because he rocketed back over to them and joined in the hunt. It was amazing to see them all work together as they chased the seal down.

On the morning of August 17th, I was out on the water with some friends at Smith Island. We were just finishing up birding (found 9 Tufted Puffins!) when I spotted dorsal fins! It was the T30s and they milled about for quite a while in the same place. It appeared that they had made a kill on some sort of marine mammal. They celebrated with tail slaps, pec slaps, half breaches, and a belly flop. Out on the Odyssey later that day, we caught back up with them off of Lopez Island. They were mainly in travel mode but likely made a harbor seal kill near the Lopez Island ferry dock. It was great to see this family again, as I had not seen them since 2012!

On August 18th, the Odyssey headed for Haro Strait to see the T46Bs. I was especially excited because I had never seen this family before! They made two harbor seal kills while were with them. The first kill took place right as we arrived on scene and T46B2 celebrated with the longest headstand I have ever seen an orca do. It seemed to last forever! The family then moved on but once out in the middle of strait they found another seal. This time, there was even more celebration! T46B1A tail slapped multiple times, T46B laid on her side her pectoral fin in the air, and T46B, T46B2, and T46B1A all happily carried chunks of seal around in their mouths as they hung out by the Odyssey! One of the young ones then spy hopped with a long chunk of seal hanging from its mouth! Needless to say, everyone were pretty excited and I was probably screaming the entire time.

On August 19th, we encountered a nice sized social group made up of the T34s, T36As, T37Bs, and T46s as they headed past Stuart Island and aimed towards Swanson Channel/Boundary Pass. It was another encounter full of everyone screaming excitedly as they suddenly surfaced nearby and decided to swim underneath the boat! We could clearly see both T34’s and T37B’s new calves as they swam by underwater. It will fun to see those two cuties grow up. What will happen next?!

Transient and Resident Orcas (7/15/17 - 8/3/17)

Since my last update, I have had lots of encounters with the marine mammal-eating transient orcas and a few encounters with salmon-eating southern resident orcas.

On July 15th, we saw the T34s and T37Bs twice on the Odyssey of San Juan Excursions. On our morning trip, we watched as the two matrilines (each with a new calf) as they hunted harbor seals along Fattop Island. They definitely made at least one kill there and celebrated with multiple spy hops. After a bit of milling around, they eventually moved over to White Rock, made another kill, and celebrated again with a spy hop, tail slaps, aerial scans, and other excited behaviors. It was amazing to see how the orcas maneuvered very close to the rocky shorelines and worked together to catch their prey. On the afternoon trip, we met back up with them up in Georgia Strait. They were slowly traveling up the strait, with their bellies likely quite full after having such a successful morning!

On July 16th, we encountered the T34s and T37Bs again on the Odyssey as they headed up Rosario Strait. It was lunch time for them as they circled and milled about at Peapod Rocks while frightened harbor seals looked on. They likely made at least one kill while we were with them and they celebrated with a spy hop and aerial scans.

On July 18th, a few salmon-eating southern resident orcas returned to San Juan Island. It was four matrilines from L pod known as the L4s, L26s, L47s, and L72s (19 out of 35 L pod members). I watched the Ls from shore as they looked back and forth along the island for Chinook/King salmon to eat. The next morning, they were already leaving the area in their search for a place with greater salmon abundance.

On July 23rd, the southern residents were back. The L4s arrived first from the Strait of Juan De Fuca, followed by the L26s, L47s, L72s, and all of J pod. We got to see more than half of the entire endangered southern resident orca population (only 78 orcas) from the Odyssey. It was great to see the Js and Ls socializing and having some fun. They seemed excited to back in what was historically their home for much of the year when Chinook/King salmon were plentiful. However, they could not stay for long and headed back out the Strait of Juan De Fuca a few days later.

Aboard the Odyssey on July 27th, we saw the T34s and T37Bs again up near Sucia and Matia Island. When we first arrived on scene they were in travel mode but they then switched to hunting mode and milled about for a bit. It was unclear if they managed to successfully catch whatever they were hunting while we were with them.

On August 2nd, the T18s came into the area from the Strait of Juan De Fuca and the Odyssey traveled up the west side of San Juan Island with them. Amazingly, when they reached Open Bay, they turned and swam into Mosquito Pass, passed Roche Harbor, and popped out in Spieden Channel. I have never heard of transients going all the way through Mosquito Pass in recent years, if ever! It was also great to see one my favorite transient males, T19B!

On August 3rd, the 19 Ls returned to San Juan Island, with the L4s arriving first, just like on July 23rd. Aboard the Odyssey, we spent time with the L4s as well as three humpbacks that seemingly felt threatened by them. They seemed to think that the L4s were marine-mammal eaters instead of salmon-eaters. The three humpbacks stuck close together, trumpeted loudly as they exhaled, and moved away from the orcas. What an interesting encounter!

The Ls started to leave the area that night and were outbound in the Strait of Juan De Fuca the next day. Since April 23rd, 2017 and as of today (August 4th), there have been only 72 Chinook/King salmon counted up at the Fraser River so it is better that they look for salmon elsewhere at this time.
