J pod returns after an extended absence

Thursday, May 16th, 2013

J pod, one of the three groups of killer whales that frequent Puget Sound, returned to the San Juan Islands yesterday after an unusually long absence.

J pod typically passes through the area throughout the winter months. It is K and L pods that spend more time in the open ocean along the West Coast. Until yesterday, J pod had been gone for more than 70 days, according to Capt. Jim Maya of Maya’s Westside Charters.

Orca Network received reports that J pod was off Victoria around noon. The pod moved east and then north along San Juan Island, shuffling along the west side between Lime Kiln State Park and Henry Island all afternoon. They were last seen heading north up Haro Strait.

Ken Balcomb of the Center for Whale Research reported that all the members of J pod were accounted for and no animals had died through the winter, which is cause for celebration. (See Orca Network’s Facebook page.) It appeared no babies had been born either. The last J pod calf was J-49, first spotted in August of last year.

K and L pods should begin to make their appearances in the inland waters in the near future. Whether they stick around probably depends on how many salmon they encounter. Typically, these Southern Resident orcas begin to roam around the San Juans and lower Strait of Georgia in early to mid-June, as chinook salmon return to rivers in the region.

Lolita, the captive orca, could gain endangerd status

Wednesday, April 24th, 2013

Lolita, a killer whale taken from Puget Sound in 1970 and placed in a Miami aquarium, could be reclassified as an endangered species, along with other endangered Southern Resident orcas. At the moment, Lolita is not listed at all.

NOAA Fisheries announced today that PETA — People for the Ethical Treatment of Animals — has provided adequate documentation to consider whether captive orcas (specifically Lolita) should be listed along with their counterparts still roaming free.

One must not presume, however, that because NOAA has accepted PETA’s petition that a listing will follow, agency officials stressed.

I was under the impression, from talking to NOAA officials last year, that we would soon know whether or not the entire Southern Resident population would be taken off the Endangered Species List, as proposed by Pacific Legal Foundation. But that decision appears to be delayed for consideration of the Lolita petition.

“The agency said to make sure that its review is complete and based on the best available science it would now solicit any new information about Lolita’s genetic heritage and status to include in the ongoing status review,” NOAA said in a news release. “A finding on the delisting petition is due next January.”

PETA filed its petition on behalf of the Animal Legal Defense Fund, Orca Network and four individuals. The 33-page petition, filed in January, applies only to Lolita, since the 35 other killer whales captured in Puget Sound have died, the petition notes. Documents — including the Lolita petition — can be found on NOAA Fisheries’ website. I discussed PLF’s delisting petition and provided links to related documents in Water Ways last Oct. 24.

The PETA petition strongly challenges the reasons for ever leaving Lolita out of the endangered population:

“No explanation was offered for Lolita’s exclusion from the listing because no legitimate explanation exists. Lolita’s biological heritage is undisputed. The Endangered Species Act unquestionably applies to captive members of a species, and the wholesale exclusion of captive members of a listed species is in excess of the agency’s authority.

“Lolita’s exclusion serves only one purpose: It protects the commercial interests of the Miami Seaquarium. The Endangered Species Act specifically precludes agency consideration of whether listing a species would cause the holder of any member of the species any economic harm. Thus Lolita’s exclusion violates the act.

“This petition urges the National Marine Fisheries Service to rectify this unjustified and illegal exclusion, thereby extending Endangered Species Act protections to all members of the Southern Resident killer whale population.

“Although as a legal matter Lolita’s genetic heritage is sufficient to merit her listing, this petition provides additional support in four sections. The first section provides the factual background regarding the Southern Resident killer whales’ listing and Lolita’s exclusion. The second section explains the application of the act to captive members of listed species. The third section applies the five factors that govern listing decisions under the act to the Southern Resident killer whales generally and also to Lolita. The fourth section considers policy reasons that support Lolita’s protection, given her significant scientific value to the wild population.”


Orca-tagging project comes to an end for now

Friday, April 5th, 2013

A research project that involved tracking the travels of K pod for more than three months in the Pacific Ocean apparently has ended, as the transmitter seems to have run out of battery power, according to research biologist Brad Hanson.

Tagged whale

“This has been a phenomenal deployment,” Brad told me yesterday after it appeared he had logged the final transmission from K-25. “It has been a quantum leap forward for us in terms of understanding what is going on.”

K-25 is a 22-year-old male orca who was implanted with a satellite tag on Dec. 29. The battery was expected to last for 32,000 transmissions, and it actually reached about 35,000, said Hanson of NOAA’s Northwest Fisheries Science Center. No data arrived yesterday during the normal transmission period.

The three months of satellite tracking data will be combined with fecal and prey samples from a 10-day research cruise to serve up a wealth of information about where the Southern Resident killer whales go and what they eat during the early part of the year, Brad said. Until now, this has been a major blank spot in the understanding of these whales, he noted.

The information gathered over the past three months should prove valuable in management efforts to protect and restore these orcas, which are familiar to human residents of the Puget Sound region. After the data are analyzed, federal officials should be able to say whether they have enough information to expand “critical habitat” into coastal areas for the endangered killer whales. If not, we should know what additional information may be required.

Brad says he feels a high level of anticipation from his fellow killer whale experts who are eager to learn of the research findings, especially the results of what the whales are eating.

“We have a tremendous amount of data, and we’re trying to push it through as quickly as we can,” he said.

Brad says he won’t release the findings until the analysis is further along. But he did dangle this intriguing tidbit in front of me: The whales are NOT eating chinook salmon exclusively.

The tracking project has another benefit, Hanson said. It will bring new meaning to more than three years of acoustic data (recorded sounds) picked up by hydrophones dispersed along the Washington Coast. Until now, it was not possible to determine the locations of the whales from their sounds alone, because the sounds could be picked up from many miles away. Now, thanks to tracking data, the intensities of their calls and echolocation clicks can be correlated with distance to a greater extent. Researchers are developing a computer model to identify possible locations from as much as seven years of hydrophone data in some places.

The tracking project began on Dec. 29, when K-25, named Scoter, was darted with a satellite tag near Southworth in Kitsap County. K-25 and presumably the rest of K pod then moved out into the ocean. Check out the tracks on NOAA’s satellite tagging website.

“We were extremely lucky to get that tag at the end of the season,” Hanson said.

It was K pod’s last trip into Puget Sound for several months, he noted, and it is a real challenge to get close enough to dart a killer whale, especially when only certain ones are candidates for the tag.

By Jan. 13, the whales had reached Northern California, where they continued south, then turned around at Point Reyes north of San Francisco Bay. They continued to wander up and down the West Coast, including Northern California, into early March. After that, they began to stay mainly off the Washington Coast with trips into northern Oregon. They seemed to focus much of their attention near the Columbia River, where early runs of salmon may be mingling.

The research cruise, originally scheduled for three weeks, ran from March 1 to March 10, cut short by the federal budget sequestration. By following the whales, researchers were able to collect 24 samples of prey (scales and/or tissues of fish) plus 21 fecal samples from the whales themselves. Shortly before the cruise, K pod met up with L pod, probably off the Washington Coast.

The ability to track the whales and the fortune of decent weather were major factors in the success of the research cruise, Brad said. In contrast, several previous cruises had netted only two prey samples and no fecal samples.

“We are ecstatic about the amount of data we collected in such a short period of time,” Brad told me. “If we would have had 21 days instead of 10, just think what we could have done.”

Tagging the whales with a dart, which penetrates the skin, has been controversial among whale observers. Some contend that we already know that the whales spend time in the Pacific Ocean, and maybe that’s enough.

But Brad says many detailed findings from the past three months were never known before — such as how much time the whales spend off the continental shelf and how much time they spend in and around canyons at the edge of the shelf.

The sampling of fish scales and fish tissues should reveal not only the species of fish, but also specific stocks of salmon as well as their age, Brad said.

“Are they actually targeting the larger and older fish?” he wondered. “Some fish are resident on the continental shelf. Are they targeting those? Are they going after the ones they can easily detect, which means not going after the smaller fish?”

The cruise also collected all kinds of information about the ecosystem, ranging from ocean depths to zooplankton to the kinds of birds seen in the area. All that information will feed into a description of the essential habitat the whales need during their winter travels.

During the cruise, another whale, L-88, a 20-year-old male named Wave Walker, was tagged as an “insurance policy” to allow the whales to be tracked if K-25′s transmitter failed. A shorter dart was used on L-88, and the tag apparently fell off about a week later.

The ocean environment is very different from Puget Sound, where the habits of the whales are well known, Brad explained. In the San Juan Islands, groups of whales are rarely far apart compared to the scale of the ocean, he noted.

In the ocean, the orcas were generally grouped up during resting periods. Sometimes Ks and Ls were together; other times they were apart. When they were foraging, however, the individual animals might be spread out for miles.

Brad said he expects to put the new information into some kind of agency report, probably followed by a peer-reviewed journal article.

“We have put a lot of time and effort to get to this point,” he said, adding that the researchers feel a sense of accomplishment now that the effort has paid off.


‘Ways of Whales Workshop’ to feature new info

Monday, January 21st, 2013

Orca Network’s annual “Ways of Whales Workshop” on Whidbey Island Saturday has lined up some great speakers this year.

The cost of the daylong workshop is $30, or $25 for students and seniors. If you register right away, you can buy lunch for an extra $10. Visit the website for registration and additional information.

Peter Ross, a researcher with Canada’s Department of Fisheries and Oceans, will discuss toxic pollution and whales in a talk titled, “Of Whales and Men: Ocean Pollution in the 21st Century.” Peter is a leading researcher in the effort to determine why killer whales in the Northwest are among the most contaminated mammals in the world.

Other speakers include Don Noviello of the Washington Department of Fish and Wildlife, who will discuss plans to protect marine mammals from the threat of an oil spill; John Gussman and Jessica Plumb, who are documenting in film and photos the restoration of the Elwha River; Steve Mashuda, an attorney for Earthjustice who will review legal attempts to remove the Southern Resident killer whales from the Endangered Species Act; and Howard Garrett of Orca Network, who will present a theory about why male orcas stay with their mothers for life.

Sustainable Cinema Series

Another event worth noting is the film “The Pacific Rim: Americas” about the dynamic geology of the West Coast.

The film will be shown Thursday at 6:30 p.m. at the Dragonfly Cinema in Port Orchard. Jim Bolger of the Puget Sound Partnership will lead a discussion during the event. A $5 donation is suggested. See Kitsap County’s news release for details.

The film is being shown as part of the Sustainable Cinema Series, sponsored by Kitsap County Commissioner Charlotte Garrido, who hopes the films will stimulate discussion about environmental issues.


Satellite tracking shows K pod has reached California

Tuesday, January 8th, 2013

UPDATE, Jan. 11, 2013

K-25 and presumably all of K pod traveled south all day yesterday, reaching an area just north of Point Reyes National Seashore this morning. Will they linger near San Francisco or continue on to Monterey Bay, the southernmost location ever reported for the Southern Residents? See map posted on Orca Network’s Facebook page.

UPDDATE, Jan. 10, 2013

As of this morning, K pod had moved south about 150 miles in 24 hours to an area just north of Fort Bragg, Calif. See the map on Orca Network’s Facebook page.

UPDATE, Jan. 9, 2013

It appears that K pod has chosen to hang out for awhile outside of Humboldt Bay near Eureka, Calif., not far from where the pod was located yesterday via satellite transmissions. Recent movements can be seen on the map posted on Orca Network’s Facebook page.

Ken Balcomb of the Center for Whale Research met up with Jeff Jacobson of Humboldt State University yesterday. Ken spotted from shore while Jeff took his boat out to photograph the whales, according to Brad Hanson of the Northwest Fisheries Science Center. During the foraging, Jeff was reported to have picked up some fish scales to identify what the whales were eating, and he may have gotten some fecal samples as well, according to Brad.

The weather is a little rough to get out on the water today, but conditions may improve over the next day or so, Brad told me.

In the 10 days that a satellite transmitter has been attached to K-25, this 21-year-old male killer whale has traveled from South Kitsap to Northern California.

K-25 — and presumably all of K pod — was reported off Eureka, Calif., this morning. Where the whales will go from there is a matter of intense interest among orca researchers.

This is the first time that the endangered Southern Residents have ever been tracked for more than three days in the open ocean, and researchers have told me they are somewhat surprised at their pace of travel.

I wrote about the tagging project in Sunday’s Kitsap Sun, where I briefly touched on the controversy over whether it is wise to attach these barbed tags to the endangered orcas. For now, there’s not much more to be said.

Final report issued on chinook-orca connection

Sunday, December 2nd, 2012

The final report on how salmon fisheries may affect Puget Sound’s endangered killer whale population has been released by a seven-member independent panel of U.S. and Canadian experts.

Download “The Effects of Salmon Fisheries on Southern Resident Killer Whales” (PDF 1.8MB)

It appears that the findings of the report are substantially the same as what I reported in a Kitsap Sun story on May 6. If you haven’t read the story, I think you will find all the comments interesting.

The next step will be for NOAA officials to issue recommendations from the report. In light of the findings and the uncertainty about the effects of reduced fishing, it seems likely that more studies will be proposed rather than an immediate adjustment to harvest.

I’ll continue to follow this story through the public review process, which is planned for early next year. Updates and related documents can be found on NOAA’s website.

The management plan for Puget Sound chinook fisheries will remain in effect through next year, after which time it will need to be updated in consultation between state and federal agencies. Chinook are a “threatened” species under the Endangered Species Act. See NOAA’s webpage, “Puget Sound Chinook Resource Management Plan.”

Endangered orca listing comes under formal review

Tuesday, November 27th, 2012

NOAA has agreed to conduct a status review to determine if Puget Sound’s killer whales should remain on the Endangered Species List.

The agency received a petition from the Pacific Legal Foundation, which claims that the three Southern Resident pods should be considered just a part of a larger population of orcas. According to the PLF, the Southern Residents do not meet the legal definition of “species” that qualifies them for listing:

“The term ‘species’ includes any subspecies of fish or wildlife or plants, and any distinct population segment of any species of vertebrate fish or wildlife which interbreeds when mature.”

The 62-page PLF petition (PDF 384 kb) — filed on behalf of three parties, including California farmers — argues from a carefully constructed legal analysis that says NOAA should never have listed the Southern Residents in the first place.

When I first read the petition in August, I believed it was just an effort to rehash the legal arguments that NOAA went through during the listing process, following a federal court order in 2003. But NOAA apparently sees things differently, according to a news release issued yesterday:

“NOAA said the petition presents new information from scientific journal articles about killer whale genetics, addressing issues such as how closely related this small population is to other populations, and meets the agency’s standard for accepting a petition to review.”

NOAA apparently is taking a close look at a 2010 study led by Malgorzata Pilot, which was used by the petitioners to argue that the Southern Residents are not genetically isolated. From the petition:

“The significance of the findings of Pilot et al. (2010) is threefold.

“First, they demonstrate with data that social interactions among killer whale pods do occur in the wild and they occur more frequently than has been reported (i.e., many interactions are simply ‘missed’ by human observers who cannot watch a vast area of ocean to take note of killer whale pod interactions, 24 hours a day, 7 days a week, year round)….

“Second, Pilot et al. (2010) explain why inbreeding is not a problem even though killer whales rarely disperse outside of natal pods….

“Third, Pilot et al. (2010) explain why mtDNA haplotypes (groups of genes that are inherited together by an organism from a single parent) can be highly divergent among ecotypes but not nuclear DNA markers….Therefore, if only mtDNA is considered in an analysis, the loss of mtDNA variation in populations (also referred to as lineage sorting) can give an erroneous appearance of populations (and putative species) being genetically isolated because they are trying to maintain taxonomic differences while at the same time ecotypes and populations are not isolated for nuclear genetic variation.”

Sorry if that’s a little technical, but it shows why NOAA decided to take up to an additional nine months to decide if the petitioners have a case based on arguments about genetic isolation. Are the Southern Residents a distinct population segment of the overall species?

The petitioners argue that NOAA improperly declared the Northern Pacific killer whales (Northern and Southern Residents) as a subspecies, making the Southern Residents a DPS of a subspecies — which, they argue, is illegal under the Endangered Species Act.

In response to NOAA’s status review, the Center for Biological Diversity, which fought the first legal battle over the listing, issued a news release saying that nothing has changed in the realm of science. The population qualifies as a DPS, because it is one of only a few to feed extensively on salmon; it has a unique dialect; and it is genetically unique.

Stated Sarah Uhlemann, an attorney at the Center for Biological Diversity:

“It would be a tragedy to strip Washington’s most iconic species of protections. Only around 85 southern resident killer whales are left, and their Endangered Species Act listing is critical to the population’s recovery in Puget Sound.

“Nothing has changed in the science to show that orcas are faring any better or are somehow suddenly undeserving of endangered species protections. Although the agency’s decision to consider the delisting petition is unfortunate, the species’ status is unlikely to change as a result of the agency’s review, and these irreplaceable killer whales will almost certainly keep their protections.”

Other news stories on NOAA decision to review the listing:

Bill Sheets, The Herald, Everett: “Calif. farms challenge state orcas’ endangered status”

Linda Mapes, Seattle Times, “California farmers want orcas taken off endangered-species list”

Meanwhile, in terms of classifying orcas, there is an ongoing effort to include captive killer whales among the population listed as endangered. See Water Ways, Oct. 24, 2010.

And there’s a new story by Associated Press reporter Dan Joling, who writes about an effort to declare transient killer whales a new species and name them for the late Michael Bigg, a killer whale researcher who developed today’s common method for identifying individual orcas.


Orcas hunt for chum salmon in Central Puget Sound

Wednesday, October 10th, 2012

The Southern Resident killer whales have begun their annual travels into Central and South Puget Sound in search of chum salmon.

The shift occurs when chinook salmon have completed their migration and chum are just beginning to come home to their natal streams, as I describe in a story in yesterday’s Kitsap Sun. It is widely assumed that the length of their stay depends on their success in finding the later salmon.

This year was predicted to be a low year for fall chum. But Jay Zischke, marine fisheries manager for the Suquamish Tribe, told me that early commercial and test fisheries suggest that the run is either earlier than usual or larger than the preseason forecast. Even so, it may still be a relatively low year for fall chum.

This is the 15th anniversary of another low chum year, 1997, when 19 members of L pod came all the way into Dyes Inlet to find adequate numbers of chum schooled up in front of Chico and Barker creeks. The whales stayed in the inlet for a month and left just before Thanksgiving. There is still debate about whether they wanted to stay that long.

On the 10th anniversary of the event, I wrote about the story of two young researchers, Kelley Balcomb-Bartok and Jodi Smith, who spent most of that month studying the whales and trying to protect them from a massive number of boaters who wanted a front-boat view of the action. Stories, maps and other information about that event can be found on a website called “The Dyes Inlet Whales — Ten Years Later.”

Orca calves are given names for the first time

Thursday, September 13th, 2012

The votes are in, and three young killer whales born into the Southern Resident community in 2010 and 2011 have officially been given names by The Whale Museum.

The newly named babies are: Ripple (K-44), Keta (L-117), and Jade (L-118).

Ripple (K-44)

Getting a name means an orca calf has survived through its first year, a period of high mortality among killer whales.

Naming involves nominations for likely monikers followed by voting, which this year generated about 5,000 votes.

Here’s some info behind the names and the animals themselves. Thanks go to Jeanne Hyde and The Whale Museum for the photos and comments about the youngsters:

Ripple: The definition of ripple means “to form or display little undulations or waves on the surface.” It is also the name of an island located in the San Juan Islands. Though a ripple and Ripple Island may both be small, young Ripple will hopefully grow to leave large ripples on the surface of the water.

Ripple, born in 2011, is the first offspring of Deadhead (K-27). He was first seen early in the morning, along the west side of San Juan Island, traveling in his mother’s slipstream. Ripple’s grandmother is Skagit (K-13). He has one cousin Comet (K-38), one aunt, Spock (K-20), and two uncles, Scoter (K-25) and Cali (K-34). Kitsap Sun, July 7, 2011.

Keta (L-117)

Keta: Keta is another word for chum salmon, a fish the Southern Residents feed on in the fall. One of Keta’s brothers is named Coho (L-108), another type of salmon the whales occasionally eat. Another brother is named Indigo (L-100).

Keta was born in December 2010 to Ino (L-54), who was born in 1977. Keta’s sex has not yet been determined. Kitsap Sun, Dec. 8, 2010.

Jade: Jade is a gem stone. Jade’s mother, Nugget (L-55), and one sister, Lapis (L-103), have gem stone names. Jade was first seen on May 29, 2011, as several L Pod family groups traveled south through Trincomali Channel, B.C. They had arrived from the north, which is not common for them. In addition to Lapis, Jade has two living siblings, Kasatka (L-82) Takoda (L-109). Jade’s sex is still unknown.

Jade (L-118)

These three orcas are now ready for “adoption,” a fund-raising promotion by The Whale Museum, as explained in a news release issued yesterday:

“The Orca Adoption Program was started in the spring of 1984. The rationale behind the creation of the adoption program was that if each orca were given a name and history, people would understand its unique personality and complex social relationships, and form a connection to the whales.

“At the time the Orca Adoption program was created, a congressional bill to ban live captures of killer whales was pending; it subsequently passed. Today, thousands of people know Granny (J-2), Oreo (J-22) and other Southern Resident orcas through the Orca Adoption Program.

“An Orca Adoption is a wonderful way to connect with these magnificent orcas. Symbolically adopting a whale in the Southern Resident Community also supports the mission of The Whale Museum which, since 1979, has been promoting stewardship of whales and the Salish Sea eco-system through education and research. In addition to providing exhibits and the Orca Adoption Program, the Museum provides programs including: the Soundwatch Boater Education, Marine Naturalist Training, San Juan Islands Marine Mammal Stranding Network and the Whale Hotline. For information, visit The Whale Museum website.”


Orca tagging raises questions about research

Wednesday, December 8th, 2010

Killer whale researchers and advocates are beginning to stir a little bit in response to a proposal by federal researchers who want to attach satellite transmitters to the dorsal fins of up to six Puget Sound killer whales. I reported on the plan in Sunday’s Kitsap Sun.

The benefits of these satellite tags would be to track the Southern Residents during winter months when they head out into the ocean and disappear for periods of time. Knowing where the whales go is important if people are going to protect their habitat, according to Brad Hanson, chief investigator with the Northwest Fisheries Science Center, a research arm of the National Marine Fisheries Service.

It is conceivable that the whales are visiting some favored spots for hunting salmon. Finding and protecting important forage areas from human intrusion could increase the whales’ chances of long-term survival, officials say.

On the other hand, some observers are raising concerns about this research project as well as the cumulative effects of all research on the endangered killer whales. To attach a satellite transmitter, a boat must get close enough to an orca for an operator to fire a dart from an air gun. The dart penetrates the skin on the dorsal fin of the animal.
