Update on the travels of J pod along with new calf

map 1-12

J pod crossed the Canadian border and came into Puget Sound over this past weekend, allowing Brad Hanson and his fellow researchers to meet up with whales.

Brad, of NOAA’s Northwest Fisheries Science Center, was able to locate the killer whales from a satellite transmitter attached to J-27, a 24-year-old male named Blackberry.

As you can see from the chart, the whales swam south, then turned back north near Vashon and Maury islands. The researchers met up with them Saturday morning on their return trip past Seattle’s Elliott Bay, according to an update on the project’s website.

The newest baby in J pod, designated J-50, was spotted with J-16, according to the report from Hanson and crew. Other reports have indicated that J-36 was also nearby, so it appears that the new calf’s mother still is not certain. Researchers agree that the mom is either J-36, a 15-year-old orca named Alki, or else Alki’s mother — 42-year-old J-16, named Slick.

The researchers collected scraps of fish left behind by the orcas’ hunting activities. Fecal samples also were collected. Those various samples will help determine what the whales were eating.

Orca Network published photos taken by whale observers near Edmonds north of Seattle as well as from Point No Point in North Kitsap.

Yesterday, J pod headed out into the Strait of Juan de Fuca. The map shows them at the entrance to the strait going toward the ocean at 6:15 this morning.

Orca Network reports that K and L pods apparently headed into Canada’s Strait of Georgia on Friday, as J pod moved into Puget Sound. It sounds like the two pods missed each other. We’ll see if they meet up in the next few days.

Meanwhile, at least one group of transient killer whales has been exploring South Puget Sound for more than 50 days, according to the Orca Network report. That’s a rare occurrence indeed. A second group of transients has been around for much of that time as well.

It’s a girl! Orca gender identified; her mother remains a mystery

Thanks to a baby photo from Jane Cogan, the newest killer whale in J pod has been identified as a girl, according to Ken Balcomb of the Center for Whale Research.

We still don’t know whether the mother is 42-year-old J-16, known as Slick, or Slick’s 16-year-old daughter J-36, known as Alki. At moment, the family group, which consists of J-16, her three offspring plus the new calf, are sticking close together.

“It may take a little time for us to sort it out,” Ken told me, but the mother should become apparent within a few weeks, if not sooner, because the calf must be getting milk from the mom. From all indications, the little one is doing fine.

Initially, the calf was thought to be the offspring of J-16, because J-36 was some distance away. But now it seems just as likely that J-16 was babysitting while J-36 got some rest, Ken told me.

Yesterday, Jane and Tom Cogan of San Juan Island took an overnight trip up north into British Columbia, where J pod has been swimming near Texada Island since the beginning of the new year. Jane sent back a good photograph of the baby’s underneath side. According to Ken, it is not unusual for mothers to roll their babies near the surface of the water.

Female killer whales have a more rounded pattern in the genital area, while males have a more elongated pattern of coloration. A good photo is all it takes to tell a boy from a girl. For comparison, see Questions & Answers at Center for Whale Research website.

I talked to Tom briefly this afternoon. He told me that J-50 was acting playful at times, like young whales will do, with some tail slapping and porpoising.

“I would say it looked healthy,” he said. “It was following J-16 a lot of the time, but all of the family was in the area, and they would group up at times.

“We’ll show Ken our pictures and debrief him when we get back,” he added.

Because J-27, a male in J pod, has been carrying a satellite transmitter since Dec. 28, experts have a pretty good idea about their location, as the orcas move about. Check out the maps on NOAA’s website, “2015 Southern Resident Killer Whale Satellite Tagging.”

As of this afternoon, J pod, including the J-16 clan, was near Nanaimo, B.C., and headed south toward the Washington border, according to Tom Cogan, who was in the vicinity.

J pod will be tracked by satellite again this year

A 24-year-old male orca named Blackberry, designated J-27, has been carrying a satellite transmitter since Monday, allowing experts to track the movements of J pod.

The research project, started in 2011 and led by Brad Hanson of the Northwest Fisheries Science Center, is designed to figure out where J pod goes in winter and early spring. J pod does not seem to travel far down the West Coast, as K and L pods do.

As luck would have it, the satellite tag was in place Wednesday when a portion of J pod headed into East Sound on the south side of Orcas Island. A day later, they were seen by observers with a new calf, J-50, which I reported in Water Ways yesterday and updated today. Nobody seems to recall the whales ever going into that waterway, as suggested by comments to a post on Orca Network’s Facebook page yesterday at 5:19 p.m. It’s long been speculated that orcas seek out calm waters, when possible, to give birth.

The mother of J-50 is still a mystery, though it could be solved as observers notice which adult female is spending the most time with the young animal.

After J-27 was tagged about equidistant from Sequim, Whidbey Island, San Juan Island and Victoria, the whales worked their way through the islands near the Canadian border, then moved north to Texada Island in the Strait of Georgia, east of Comox, B.C. As of this morning, they were still traveling around that general vicinity, as you can see from the map on this page and previous maps on the project’s webpage. The page called “2015 Southern Resident Killer Whale Satellite Tagging” also contains information about the project’s goals.

I have written about these tagging efforts and the controversy surrounding them since permits were first proposed under the Endangered Species Act. You’ll find last year’s stories and links to previous stories in Water Ways on Jan. 3, 2014, and later on Jan. 14, 2014. You can also search the blog for “satellite and orcas” to find just about everything I’ve blogged about on the topic.

J-27 and other members of J pod moved into East Sound near Orcas Island on Monday. The cluster of points represent travels between 4 and 5 a.m. the next morning. A newborn orca was spotted Wednesday.

Oldest orca mom to give birth offers twist of fate for Puget Sound whales

UPDATE, JAN. 2, 2015

After thinking it over, Ken Balcomb of the Center for Whale Researchers says it is likely that J-16 is the grandmother of the new calf, not the mother.

J-16, known as Slick, could have been babysitting the young whale when the two were spotted by observers. If so, the mom is probably J-36, a 15-year-old female named Alki, who was following a few miles behind at the time.

The pattern of older whales taking care of young relatives has been seen many times before, occasionally even with newborns, Ken told me. The mother may have needed some time for rest and recovery after giving birth, especially if it was a tough delivery, he said.

The baby had evident scratches, known as “rake marks,” on its back and dorsal fin caused by the teeth of another killer whale, Ken said. He believes it could be an indication that the grandmother assisted with the birth.

Whoever the mother is, the baby’s condition indicates that it has been nursing, and that’s a good sign.

If J-16 is the mother, she would be the oldest known orca to give birth among the three Southern Resident pods. If it is J-36, then the young mom could need help from her own mother.

If J-36 is the mom, then she should be spending most of her time with her new baby. That could come within a few days or up to a couple weeks, Ken told me. Observers are making a special effort to see who is spending time with whom over the next few days.

“This is an interesting little mystery,” Ken said. “If the whales do their part, we should be able to figure it out.”

Tracking them could be made easier because of a satellite tag attached to another member of J pod — J-27, a 24-year-old male named Blackberry. The barbed tag was attached to the whale’s dorsal fin in open waters about equidistant from Sequim, Whidbey Island, Victoria and the south end of San Juan Island. Since then, the whales have moved north into Canada. I’ll soon have a separate blog post on the tracking study.

A newborn killer whale, reported Tuesday by the Center for Whale Research, was identified as the offspring of 42-year-old J-16 — the oldest known orca to ever give birth among the three Puget Sound pods.

“No other female has given birth at over 42 years of age in the four decades of demographic field studies of the Southern Resident orcas,” according to a statement from Orca Network. “J-16 was not expected to be carrying a calf due to her advanced age.”

It’s odd how the circumstances have worked out. The birth of this new calf, designated J-50, becomes the first major news story about the Southern Residents since we heard about the death of J-32, named Rhapsody. See Water Ways for Dec. 7 and a later report on Dec. 12.

Rhapsody was only 18 years old when she died carrying an unborn calf. Before her death, experts had high hopes that Rhapsody would live long and produce many babies. If she had ever given birth before, her offspring died before they were noticed by observers.

So it is that we have the death of a young killer whale with an unborn calf and now a new birth to an older whale thought to be beyond reproductive age. Let’s hope this new baby orca survives, lives long and contributes to the endangered killer whale population.

J-16, named Slick, has six known offspring, including the new baby. Three others are still alive: J-26, a male named Mike, born in 1991; J-36, a female named Alki, born in 1999; and J-42, a female named Echo, born in 2007. The deceased offspring are a male that died at 14 years of age in 2010 and a baby orca that died in 2011 after living about a month.

The birth and death records are maintained by the Center for Whale Research. Young orcas are typically given names by The Whale Museum in Friday Harbor after they survive through a winter.

The population of the Southern Residents now stands at 78 — down from 88 less than four years ago.

Ken Balcomb offers his personal observations about J-32’s death

UPDATE, DEC. 17, 2014
A news release sent out yesterday by the Canadian Department of Fisheries and Oceans confirms what Ken Balcomb suspected when I interviewed him on the day the necropsy was performed. See also Associated Press story by reporter Phuong Le.
—–

Ken Balcomb of the Center for Whale Research has written an excellent report about the recent death of J-32, the Southern Resident orca that died with an unborn and decomposing offspring inside her.

Ken’s report talks not only about his observations of the necropsy, which I reported in Water Ways on Saturday, but it also includes his observations as he watched the young whale grow up:

“The decade around the millennium was a difficult time for the J10 matriline – J32’s mom (J20) died at the age of seventeen in 1998 when J32 was only two years old; her grandmother (J10), who took over her care, died at the age of thirty-seven in 1999, when J32 was only three years old; and her uncle (J18) died at the age of 23 in 2000. All died young relative to the average lifespan of 50+ for females and 29 for males in this species.

“Fortunately, auntie J22 at age thirteen gave birth to a baby (J34) in 1998, and provided orphaned J32 the required nurturing of a ‘mom’. With that nurturing from grandmother and auntie, including perhaps a little milk, J32 made it through her infancy and into her teens to be a very vivacious young whale, full of energy.”

Ken writes eloquently about his concerns regarding the high levels of toxic contaminants carried in the blubber of the Southern Resident orcas. The contaminants are known to cause problems with the immune and reproductive systems. They also can cause brain deficits that can lead to behavior disorders. He writes:

“These pollutants are released to circulate in the bloodstream when the whales’ blubber fats are metabolized for energy when fresh food is scarce. It is like having a freezer full of tainted and freezer-burned food that you never have to eat unless there is nothing in the grocery store. When nothing else is available the bad stuff is taken out of storage and circulated for body needs.”

Ken also repeats his plea for people to take action in the face of ongoing disaster for the local killer whale population — including this sudden death of a young mother known as Rhapsody and her unborn offspring.

“This is a very ugly situation for the population of Southern Resident killer whales – our beloved orca. I think we must restore abundant healthy prey resources ASAP if these whales are to have any chance of avoiding extinction. The critical point for their recovery may already have passed. I hope not, but it will soon pass if we do not take immediate action.”

Ken’s full report is well worth reading. It can be found on the website of the Center for Whale Research or you can download the title, “Preliminary Necropsy Report for J32” by Kenneth Balcomb, Center for Whale Research.

Hope of seeing larger orca population dashed by calf’s death

A seven-week-old baby orca born to our Southern Resident pods was reported missing and presumed dead today. This was the newborn orca who brought so much hope and excitement to our area, being the first reported birth in more than two years.

When I called Ken Balcomb this morning, he was in a “subjective” state of mind, as he put it. Ken, of the Center for Whale Research, has been keeping track of the three Southern Resident pods since 1976, and he’s clearly worried that these whales may be headed for extinction.

As we talked on the phone, Ken was peering through the large windows of his home on San Juan Island and watching a large purse seine vessel scooping up chum salmon and possibly other species as bycatch.

“I look at this every day, and I’ve seen this for almost 40 years,” Ken said. “There is no letup on the human part. Virtually no fish are getting past the outlet. We know the Fraser River runs are in poor shape, and our management doesn’t seem to take any kind of ecosystem approach.”

Salmon biologists set the sport and commercial fishing seasons based on an estimate of the number of fish returning. They update that estimate during the season based on harvest numbers caught in the nets.

“Whatever they are doing, it obviously has not worked, since we’ve seen run after run not doing well,” Ken said. “I get subjective about it and wonder when our society is going to do something to get more prey (for the whales).”

Ken said there was much hope for the seven-week-old orca, designated L-120, the third known offspring of the 23-year-old mother designated L-86.

“I was optimistic,” he told me. “When we first saw the baby, it had a squished-looking head, but even human babies can be born with a flattened head.

“Within a week, it was filling out well and was energetic,” he continued, and there was no reason to believe the calf would die.

The Southern Residents are known to bear a heavy burden of toxic chemicals, but transient killer whales are even more contaminated. The difference may be that transients, which eat marine mammals, may be getting enough food. Was the orca mom unable to nurse her baby? Did the toxic chemicals cause an immune deficiency? Or was there another problem? We’ll probably never know.

All three orca pods were probably out in the ocean when the youngster disappeared. The mom was seen with other whales on Friday, Saturday and Sunday without the calf — something that would not happen if the baby were alive.

L-120 was the third calf born to L-86. Her second calf, L-112, washed up dead at Long Beach in February 2010. After much investigation, researchers concluded that L-112 had died of blunt force trauma, but what caused the injury was never determined. Ken suspects some kind of explosive detonation, although that cause was discounted by investigators.

Howard Garrett of Orca Network said the orcas have faced a shortage of food, toxic chemicals, routine shooting with guns and a series of captures that depleted the population.

“We haven’t treated these magnificent orcas well at all,” Howie said in a news release. “As a society we are not successfully restoring this orca community, despite the many warnings and legal declarations.

“Our challenge is clear: Bountiful salmon runs must be restored and protected or we won’t see resident orcas in the Salish Sea in coming years,” he added.

The latest population count places the total number at 78, the lowest number since 1986, according to records by the Center of Whale Research.

Killer whales expected to head south any day now

UPDATE, Oct. 4
Orca Network reported a brief appearance of J pod this week near San Juan Island: “On Wednesday, October 1, J pod plus L87 Onyx and a few K pod members shuffled in small groups spread out up and down the west side of San Juan Island for over eight hours, then returned around midnight and continued vocalizing near the Lime Kiln hydrophones for another few hours.”

As chum salmon swim back to their home streams in Puget Sound this fall, three killer whale pods — the Southern Residents — can be expected to follow, making their way south along the eastern shoreline of the Kitsap Peninsula.

These forays into Central and South Puget Sound could begin any day now and continue until the chum runs decline in November or December. The Southern Residents, which typically hang out in the San Juan Islands in summer, have not been spotted for several days, so they are likely somewhere in the ocean at the moment, according to Howard Garrett of Orca Network.

This year, Orca Network has created a map of good viewing sites to help people look for whales from shore. As the orcas move south into Puget Sound, Orca Network’s Facebook page becomes abuzz with killer whale sightings. Observers can use the information to search for the whales from shore.

From my experience, it takes a bit of luck to find the orcas, because they are constantly moving. But the search can be fun if you consider it an adventure and don’t get too disappointed if you don’t find the whales right away.

Howie said expanding the network to include more land-based observers can help researchers track whale movements and occasionally go out to pick up samples of their fecal material or food left over from their foraging, helpful in expanding our knowledge about what they are eating.

Whale reports may be called in to Orca Network’s toll-free number: (866)-ORCANET, emailed to info@orcanetwork.org, or posted on Facebook, www.facebook.com/OrcaNetwork.

The new Viewpoints Map shows locations where killer whales have been sighted in the past, or else they lie along a known route of their travels.

I told Howie about a few good viewing locations in Kitsap County, based on my experiences, and he said he would welcome ideas from others as well.

“It’s a work in progress,” Howie said. “They just need to be locations that are public and accessible.” If you know of a good whale-watching spot, you can contact Howie or his wife Susan Berta by email, info@orcanetwork.org.

If offering a location for the map, please give a clear description of the site and state whether you have seen whales from that location or just believe it would work based on the view of the water.

Some people have expressed concern that real-time reports of whale movements may encourage boaters to go out and follow the orcas in Puget Sound, disturbing their feeding behavior at a critical time of year. But Howie says Orca Network has increased its reporting through the years and has not heard of many problems.

“It seems like a potential problem that never really happens,” he said.

Winter weather and rougher seas makes it difficult to find the whales from the water, Howie noted. As in summer, boaters are required by federal regulation to avoid interfering with their travels. See the “Be Whale Wise” website.

When reporting whale sightings to Orca Network, observers are asked to list the species, location, time, direction of travel and approximate number of animals. When reporting killer whales, the number of adult males with towering dorsal fins should be noted. Also report any behaviors, such as breaching, spy-hopping or feeding. Good photographs are especially valuable.

Sighting reports can be found on the Orca Network website, Facebook page or Twitter feed. One can also sign up for email alerts from the website, which includes reports of recent sightings as well as archives going back to 2001. The site also tracks news and research developments.

As Howard stated in a news release:

“We are very fortunate to live in a place where we can look out from nearby shorelines and see those majestic black fins parting the waters. We are thankful for the hundreds of citizens who report sightings each year, providing valuable data to help in recovery efforts for the endangered Southern Resident orcas.”

Orcas Dyes

Erich Hoyt will talk about orcas and more

Erich Hoyt, who has been enjoying adventures with killer whales and other sea creatures since the early 1970s, will share his understanding of the underwater world during a series of presentations from British Columbia to Northern California.

Erich Hoyt
Erich Hoyt

The tour begins today on Saturna Island in British Columbia. For the full schedule, visit The Whale Trail website.

Erich has a rare talent. He is both an engaging writer as well as an experienced scientific researcher. His first book, “Orca: A Whale Called Killer,” is essential reading for orca supporters. His understanding of the oceans has led him into the field of conservation, seeking greater protections for marine habitats throughout the world.

As Erich prepared for his upcoming tour, sponsored by The Whale Trail, I had the privilege to visit with him for more than an hour via Skype from his home in Bridport, England.

We discussed how people’s attitudes in the U.S. and Canada have changed since 1973. That was when Erich’s curiosity was sparked by encounters with Northern Resident orca pods in British Columbia, where he had moved from the U.S. with his family.

Those were the days when little was known about killer whales. Orcas were still being captured in the Northwest and sent to aquariums throughout the world. Since then, we have learned how those first captures had a serious effect on the close-knit orca communities. Continuing threats today include pollution and a lack of chinook salmon, the primary prey of orcas.

In 1999, Erich helped start a research program in Russian to bring the same kind of scientific scrutiny and conservation concerns to killer whales on the opposite side of the ocean. That program, involving Russian scientists, revealed the presence of two types of orcas, those that eat marine mammals and those that eat fish — similar to what we call “transients” and “residents” in the Northwest.

Orca communities identified so far in Russia range in size from 50 to 600 animals. As we’ve seen in the Northwest, cultures — such as vocal dialects and feeding habits — are handed down from mother to offspring.

An awareness of orcas, as seen in the U.S. and Canada, has not reached Russia or many places in the world, Hoyt says. Russia still allows killer whales to be captured, and last year seven orcas were taken from the Sea of Okhotsk. Earlier captures in Russia were especially disheartening to the researchers who had come to know the individual animals taken from their families.

During his presentation, Erich will show a brief video of some of the Russian capture efforts.

In countries such as Russia, China and Japan, new marine aquariums are being built all the time, with orcas and beluga whales as the star attractions. That’s in stark contrast to the situation in the U.S., where a growing awareness of wild orcas along with the film “Blackfish” has helped change people’s attitudes about keeping large marine mammals in captivity.

Erich told me that he would like to see more people around the world come to know individual orcas by name, as we do here in the Northwest.

“Look at how far things have come, from when we didn’t know anything about them to when we start to see them as our friends,” he said.

About a week ago, I reported that NOAA Fisheries had undertaken a yearlong review to determine if the “critical habitat” for Southern Resident killer whales should be extended down the Washington and Oregon coasts. See Kitsap Sun, April 24 (subscription). A special consideration for protecting the whales from undue noise was part of the petition from the Center for Biological Diversity.

Hoyt agreed that sound should be given special consideration by the federal government.

“Rob Williams (a Canadian researcher) talks about acoustic refuges,” Erich noted. “It is a challenging issue, because whales and dolphins can hear so well… We will need much larger marine protected areas if we really want to protect them…”

A general increase in noise levels in the ocean can lead to habituation by marine mammals, he noted. As they grow accustomed to louder sounds, the animals may adjust — but how will that affect their ability to communicate and find prey? What are the prospects for their long-term survival under more noisy conditions?

And then there is the special issue of mid-frequency sonar, which can cause temporary or even permanent hearing loss for some species. Navies that use sonar must be extra careful to avoid impacts, he said.

Erich and I also talked about L-112, the young female orca that washed up dead near Long Beach about the time the Royal Canadian Navy was conducting exercises far to the north. Investigators were unable to determine what caused the “blunt-force” injury to the animal. But they ruled out explosives being used by the Navy, because the currents were in the wrong direction and the distance was too great.

“This brings to mind the crash of the Malaysian jetliner,” Erich said. “You know something unusual happened, but it defies almost any explanation you bring up. Scientists tend to come up with explanations that are the simplest … but they should be careful not to rule anything out.”

Killer whale researcher Ken Balcomb has suggested that L-112’s mother may have carried her dead daughter to the area where she was found. Hoyt said he has personally observed a female white-sided dolphin carrying her dead offspring for more than two hours in Northern Japan.

“It was really touching. We didn’t know at first if the baby was dead. We were not very close. But eventually the mother just let go of the baby.”

Erich expects mixed audiences at his upcoming appearances — from people who know more about certain issues than he does to people who are dragged to the event by a friend.

One message will be that people can watch whales from shore without causing them any disturbance. That’s the mission of The Whale Trail, the organization sponsoring Erich’s trip to locations where killer whales may be seen from shore.

I told Erich about my first adventures with killer whales during the fall of 1997, when 19 orcas visited Dyes Inlet. See “The Dyes Inlet Whales 10 Years Later.” One of my messages at that time was to encourage people to watch from vantage points in Tracyton, Chico and Silverdale.

“Land-based whale watching is really close to my heart,” Erich told me. “It’s the kind of thing that’s important for the community … and a fantastic way to get to know wildlife.”

Hoyt’s appearances in Washington state include this Wednesday in Port Townsend, Thursday in Port Angeles and May 18 in Seattle. Visit The Whale Trail website for the full schedule.

K pod makes rare spring visit to South Sound

K pod, one of the three pods of orcas that frequent Puget Sound, came south through the San Juan Islands yesterday and were spotted in South Puget Sound late this afternoon.

It’s quite unusual to see K pod coming into Puget Sound this early in the year, noted killer whale researcher Brad Hanson of the Northwest Fisheries Science Center.

K pod contains 19 orcas and is often seen with other pods, but not this time. If history is any indication, they will soon be heading back out to the ocean. They are more likely to begin hanging out in the San Juan Islands in late May or early June.

Susan Berta of Orca Network told me that whale researcher Ken Balcomb had been out with the whales Sunday and was able to account for all the animals (no deaths), but there were no new babies either.

Brad said his crew collected two fecal samples, but they may not be representative of ocean feeding, since the whales have been around for more than a day. Research has been focusing on what Southern Resident orcas eat when they are in the ocean.

The whales may have been spotted first this morning by a crew on one of the Seattle ferries. The report to Orca Network was a single killer whale a mile north of Alki Point, about mid-channel, at 7:30 a.m.

The K pod reports came amidst other reports of transient killer whales heading north from Point No Point about 9:30 a.m., passing Whidbey Island an hour later and off Everett in the early afternoon, according to reports on Orca Network. Another group of transients was reported on the other side of Whidbey in Admiralty Inlet and later seen heading west in the Strait of Juan de Fuca.

Because of the multiple transient reports, Brad said he was caught by surprise this morning when he went out and found all of K pod swimming south in Colvos Passage off South Kitsap.

Normally, resident orcas first pass Vashon Island on the east side and come north through Colvos Passage.

“We kept getting all these weird reports,” said Susan, who was kept busy posting updates to Orca Network’s Facebook page. “We heard about one lone orca off Alki, then another group, and I said, ‘I wonder if that is K pod all strung out down there.’ We were not expecting that.”

Susan said it is rare, but not unprecedented, for residents to come into Puget Sound in early spring. In March 2006, K and L pods arrived together and went all the way south to Olympia.

Video shows 30 days of tracking J pod orcas

Tracking J pod for 30 days — mostly during the month of January — lends support for the idea that this group of Southern Resident killer whales strongly depends on the inland waters of the Salish Sea, perhaps more so than K and L pods.

A satellite transmitter was attached to L-87, a 22-year-old male orca named Onyx who has been spending his time with J pod. The tracking effort is part of a study to determine where the whales travel in winter. While one month of tracking doesn’t prove much, it is interesting to know that J pod can hang out for days around Texada Island in the Strait of Georgia without being noticed.

The following video, courtesy of the Northwest Fisheries Science Center, depicts travels of the whales from Dec. 26, when the tag was attached, to Jan. 23, when the tag apparently fell off.


View large in new window.

The tracks end just as the orcas seem to be leaving the Strait of Juan de Fuca, but so far we don’t know if they continued or turned back.

When the whales moved into Central and South Puget Sound, as shown by the satellite tracks, observers watching from shore and on ferries reported the whales each time, noted Brad Hanson, who is leading the tracking study for the NOAA’s Northwest Fisheries Science Center. On the other hand, the whales were infrequently reported while in the Strait of Georgia and Strait of Juan de Fuca, he said.

“One thing that was interesting to see,” he noted, “is that the movements are completely different from what they do in summer.”

In summer, J pod often moves north into Canada but not much beyond the Fraser River near Vancouver. These winter travels show the J pod moves farther north and stays in the northern part of the Strait of Georgia for extended periods of time.

What they are finding there to eat has not been fully studied, but some percentage of chinook salmon reared in local waters are known to stay inside the Salish Sea, never swimming out to the ocean.

Past studies based on recorded killer whale calls have shown that J pod moves into the open Pacific Ocean on occasion, but the whales rarely travel very far down the coast. The recording equipment was moved this winter to strategic locations to better distinguish how far south J pod travels in winter, Brad said.

Over the next couple months, researchers will continue to look for opportunities to attach tags to killer whales, he said. A cruise aboard a large research vessel in March will attempt to follow the Southern Residents, identify their feeding areas and determine what they are eating in the ocean.
