L-84, a 25-year-old male killer whale named Nyssa, continues to
transmit his location and that of his traveling companions who keep
moving north and south along the West Coast, going as far south as
Here’s a quick update, going back to when the orca was first
A satellite transmitter was attached to L-84 on Feb. 17 by
researchers from NOAA’s Northwest Fisheries Science Center during a
research cruise focused on the Southern Resident whales. Since
then, the orca — often see with whales from K and L pods — moved
south past the Columbia River into Central Oregon before turning
back north on Feb. 21.
On Feb. 25, the researchers were following the whales in the
research vessel Bell M. Shimada off Westport in Washington when
another group of L pod whales showed up. It was at that time that a
new calf was spotted with L-94, a 20-year-old female named
The whales headed south and reached Tillamook Head in Northern
Oregon on Feb. 27, then they turned north and reached La Push in
Washington on March 1. For the next eight days, the whales moved
back and forth in the north-central areas of the Washington Coast
before moving south to Grays Harbor on March 12.
On March 13, they began an excursion to the south, reaching the
Columbia River on March 14, Cape Falcon on March 15, Depoe Bay on
March 16, Coos Bay on March 18, and the California border on March
At that time, marine mammal researcher Jeff Jacobson, based in
Northern California, caught up with the whales and confirmed that K
pod and a portion of L pod remained with the tagged whale L-84. The
whales kept moving south to Cape Mendocino (south of Eureka,
Calif.) on March 22 (Sunday), before turning back north, reaching
the Rogue River (just north of the Oregon state line) on
The tracking effort provides information about the whale’s
travels and where they may be catching fish. Work from research
vessels often involves collecting fecal samples and pieces of dead
fish to identify what the whales are eating during the winter and
I admit I’m little late to the party, since this video was
posted on NOAA’s
Facebook page three days ago., Still, I wanted to show it to
those of you who may not be closely following the killer whale
research. At the end of this video, researchers Brad Hanson and
Candice Emmons talk a little bit about their work.
It’s all about the data when it comes to critical habitat for
the Southern Resident killer whales, or so they say.
Researchers with NOAA’s Northwest Fisheries Science Center have
piled up a lot of data this year, which could be just what is
needed to expand the endangered orcas’ critical habitat from Puget
Sound and the inland waterways out to the open ocean along the West
NOAA announced in
today’s Federal Register that the agency would consider
expanding critical habitat, as allowed by the Endangered Species
Act, and possibly make other changes to the designation over the
next two years. What is needed, the agency said, are more data.
On Dec. 28, a satellite transmitter was attached to J-27, a
24-year-old male named Blackberry, who was tracked as J pod moved
about from the Strait of Juan de Fuca up into the Strait of Georgia
until the tag came off on Feb. 15. The following day, a new
satellite tag was attached to L-84, a 25-year-old male named Nysso.
K and L pods were tracked out to the ocean and down the coast to
A research team led by Brad Hanson aboard the vessel Bell M.
Shimada has kept track of J pod, then K and L pods since leaving
Newport, Ore., on Feb. 11. According to the latest report from the
researchers, K and L pods traveled south last week to the Umpqua
River in Central Oregon, where they abruptly turned north on
The whales continued north on Sunday, sometimes 10 miles
“We observed a lot of surface active behavior throughout the day
— lots of spy hops — and at one point we observed numerous whales
repeatedly breaching over a several-minute period,” according to
notes from the cruise.
The researchers observed no apparent foraging for several days
and the whales remained quiet, with the exception of a several-hour
period shortly after the breaching episode. As of yesterday
morning, they were still off the Oregon Coast and heading
The tracking data and up-close observations from this year’s
cruise appear to fill in some major data gaps — especially for J
pod, whose winter movements were not well known, according to NOAA
In 2012, the first tag deployed on the Southern Resident allowed
the researchers to track J pod, but only for three days before the
tag came off. In 2013, a tag on L-87, which frequently traveled
with J pod, provided 30 days of data about J pods movements in the
Salish Sea, particularly in the Strait of Georgia (where they spent
a lot of time this year).
Another tag in 2013 allowed K and L pods to be tracked along the
West Coast all the way to California.
Sightings from land and shore, along with acoustic recordings of
the whales also are included among recent findings.
We won’t know until 2017 if NOAA has amassed enough data to
expand the critical habitat to coastal regions, perhaps as far as
Northern California, as proposed in a petition filed in January of
last year by the Center for Biological Diversity. For the decision
announced today in the Federal Register, the data are not enough.
This is how it is stated in the notice:
“While data from new studies are available in our files and have
begun to address data gaps identified in the 2006 critical habitat
designation, considerable data collection and analysis needs to be
conducted to refine our understanding of the whales’ habitat use
and needs. Additional time will increase sample sizes and provide
the opportunity to conduct robust analyses.
“While we have been actively working on gathering and analyzing
data on coastal habitat use, these data and analyses are not yet
sufficiently developed to inform and propose revisions to critical
habitat as requested in the petition.”
In addition to the geographic areas covered by the killer
whales, the agency must identify the ‘‘physical or biological
features essential to the conservation of the species.’’ Such
features include food, water, air, light, minerals or other
nutritional requirements; cover or shelter; sites for breeding; and
habitats protected from disturbance.
Once specific areas are identified for protection, the agency
must make sure that the value of protection for the killer whales
outweighs the economic costs and effects on national security.
The young killer whale born into J pod three weeks ago still
appears to be doing well, according to Dave Ellifrit of the Center
for Whale Research, who observed the calf when her pod came through
the San Juan Islands on Monday.
In his written notes, Dave said the calf, designated J-50, was
staying close to J-16, a 43-year-old female named “Slick.”
Meanwhile, Slick’s daughter, 16-year-old J-36 or Alki, remained
some distance away.
Uncertainty has surrounded the question of whether J-16 is the
mother or the grandmother of the new calf. If she’s the mother, it
will be the first time that an orca over 40 has been known to give
birth, at least among the three pods that frequent Puget Sound.
“While all the J16’s traveled together, J36 was consistently the
farthest of the group from J50, so whatever doubts remained about
J16 being the mother are about gone.”
Ken Balcomb, who founded the Center for Whale Research, was not
with Dave during the encounter. Ken agrees that current evidence
points to J-16 being the mom, but he is still not totally
“I’m staying open,” he told me. “J-16 is certainly the primary
There remains a little matter of the “rake marks” on the back of
the baby orca — most likely caused when an adult whale used its
teeth to pull the newborn from the birth canal. A 16-year-old
female might need some help during delivery, Ken explained, and the
grandmother was the likely one to assist. Such help probably would
not be needed for an older mom, he said.
I thought that the proof of motherhood would come when we knew
who was nursing the baby. While nobody has directly observed any
nursing behavior over the past three weeks, the baby is fattening
up and staying near enough to J-16 to allow such things to
But Ken says it is possible that J-16 could be lactating — even
if she is the grandmother. It’s happened in older pilot whales, he
“It is not beyond the realm of possibility that a grandmother
could play the nurse-maid role,” he said.
There will be no certainty about the lineage, he said, until
genetic testing is performed, and that could take years — assuming
the calf survives. Such tests could come as the result of fecal
sampling or a skin biopsy performed by approved researchers
following the whales, he said.
Meanwhile, since the calf was born, J pod has been moving around
the inland waterways and well up into the Strait of Georgia in
Canada, as revealed by a satellite transmitter carried by J-27, a
24-year-old named Blackberry.
A couple times in the past two weeks, the whales went through
the Strait of Juan de Fuca and into the Pacific Ocean. But each
time they quickly turned around and came back,
Last night, Mark Malleson of Prince of Whales, a whale-watching
company, observed J pod along with K pod spread out in the Strait
of Juan de Fuca near Sheringham Point near the south tip of
Vancouver Island, according to his report posted on Orca Network’s Facebook
So far today, I have not heard any more reports, and the next
satellite data won’t be available until later.
The succession of maps on this page shows the travels of J pod
since they touched the outer coast 10 days ago. (Click on the

In the book “War of the Whales,” author Joshua Horwitz reveals,
in exquisite detail, how Ken Balcomb played a central role in
showing how Navy sonar was killing and injuring whales around the
Ken, who we know as the dean of orca research in Puget Sound,
has not been alone, of course, in the quest to get the Navy to
better protect marine mammals. Horwitz introduces us to a variety
of people, each with his or her own interest in saving the
Frankly, I was surprised at how much I learned from the book,
given that I have been covering these same issues as a reporter for
many years. What really gained my admiration for Horwitz was how he
was able to weave scientific and historical aspects of the story
into a gripping tale that reads like a detective thriller.
I consider this book to be several stories woven into one.
First, there are the personal biographies of two key players in
this conflict with the Navy. The lives of Ken Balcomb, of the
Center for Whale Research, and Joel Reynolds, of the Natural
Resources Defense Council, became intertwined with each other after
the NRDC sued the Navy over its use of sonar around whales.
Next, we are given the history of the Navy’s sonar technology,
developed to track stealthy submarines. We meet many of the Navy
officials involved, including some who became emotionally involved
with marine mammals, flipping to the other side, as Horwitz
The Navy has long controlled much of the research involving
marine mammals — the original models for sonar. At times, whales
and dolphins were even trained as military combatants, with mixed
Last, but not least, we are shown the legal arguments related to
environmental law versus the need for national security. As a
result, we see how the Navy has become more open today about the
risks to whales from its testing and training procedures.
Horwitz paints intimate portraits of many of the characters,
especially Balcomb, the biologist, and Reynolds, the lawyer. He
sees the pair coming together from different backgrounds and
uniting in their effort to protect the whales against the Navy’s
single-minded approach to national security.
“Ken was such an extraordinary character,” Horwitz told me in a
telephone interview. “He was a reluctant activist. Activism wasn’t
The story begins in the Bahamas, where Balcomb was doing
research when a mass stranding of beaked whales took place,
practically at his doorstep. Navy sonar had been suspected of
killing whales in other areas of the world, but Balcomb was able to
secure fresh tissues — essential evidence to understand how their
injuries were caused by sound waves. Balcomb also observed that the
Navy was conducting exercises in the Bahamas at the same time, and
he made the connection to the dead whales.
From there, other researchers and policy officials became
involved, but Balcomb kept pushing to keep the incident from being
swept under the rug.
“Ken’s investment was immediate,” Horwitz explained. “One night
the Navy just plowed through and decimated this population of
We learn from the book about Ken’s serendipitous life. As a
young biologist, he collected whale lungs for research by going to
a commercial whaling station still operating in California. He
later signed onto a research crew as a dishwasher, but his skills
with a shotgun earned him the lead job of tagging whales.
Balcomb joined the Navy during the Vietnam War and became a
pilot. A series of circumstances led him into Fleet Sonar School
and the Navy’s highly secretive Sound Surveillance System, or
SOSUS. At the same time, his compatriots in graduate school became
some of the top marine mammal experts for the Navy and the National
Marine Fisheries Service. His later interactions with these folks
revealed something about their past and present positions in
Horwitz ties all these pieces of the story together in a
compelling narrative that kept offering me new and surprising
tidbits of information. It took the author seven years to complete
“He kept asking over and over the same questions,” said Ken,
somewhat amused when I asked him about it. “I didn’t know if he had
confused notes or what.”
Horwitz was seeking an extraordinary level of precision and
accuracy, so that his telling of this true and controversial story
could not be assailed.
Balcomb said he could find no errors, except for the conscious
decision by Horowitz and his editors to describe two overflights by
Balcomb in the Bahamas as a single event.
Most surprising of all was the account from Navy officials,
whose story about underwater warfare has rarely been told, except
perhaps in novels by Tom Clancy and others. Horwitz said
active-duty military officials were no help to him, but he got to
know retired Admiral Dick Pittenger, who opened doors to other
“He (Pittenger) was a total career Navy guy, but he was
skeptical about the way the Navy was handling some of these
matters,” Horwitz said, noting that the admiral spent days helping
him understand anti-submarine warfare.
Pittenger wanted the story told right, and he must have been
satisfied with the result, since he offered this comment in
promotional materials for the book:
“‘War of the Whales’ is an important book about a major
post-Cold War problem: the often conflicting goals of national
security and environmental protection. The author presents this
very complex and multidimensional story with great clarity.
“I’m certain that no one who has been involved with this issue
will agree with everything in this book (I don’t). But the topic
is, by its nature, so emotionally charged and controversial that I
doubt anyone can read it without a strong personal response. The
importance of this book is that it tells the ‘inside’ story to the
wide reading public in a compelling way.”
In my mind, Horwitz did a remarkable job of capturing the
relevant facts for this complicated story. He then seamlessly
joined the pieces together into a coherent and dramatic story — one
especially important to those of us living in an area where the
Navy maintains a strong presence among an abundance of marine
Check back to “Watching Our Water Ways” tomorrow, when I will
describe more of Josh Horowitz’s personal views about his book and
what he learned along the way.
I’d like to offer something quite different for this week’s
“Amusing Monday.” It’s a 19-minute video featuring Ingrid Visser,
one of the world’s leading experts on killer whales.
One of the highlights of the video is the rescue of an orca
imperiled with a rope and buoy caught around her tail. Without the
rescue, which begins at 10:25 into the video, the whale probably
would have died. If you continue watching, you’ll see shots taken
from a camera on the whale’s dorsal fin, giving you a glimpse into
the life of a killer whale.
Ingrid’s base of operations is New Zealand, but she has been to
Puget Sound numerous times, as well as many other places where
orcas reside. I’ve always admired her for her personal approach to
understanding orcas throughout the world.
The video provides an insight into Ingrid’s life, research and
interests. It’s appropriate that it begins with her discussing
orcas with a group of young students. For more information, check
out the Facebook
page for Orca Research Trust or the related webpage for
The video was produced by a team of photographers to introduce
the new high-speed, high-definition GoPro
camera called HERO4.The video was the sixth in a series called
“The Adventure of Life in 4K.”
Like many people, I was shocked and saddened by the death of
J-32, an 18-year-old female orca who had offered an avenue of hope
for the recovery of the endangered killer whale population in Puget
We now know from yesterday’s necropsy, that Rhapsody, as she is
called, was pregnant at the time of her death.
“Yes, she was pregnant, near-term, 80 percent or plus,” Ken
Balcomb told me last light after participating in the examination
of the body near Courtenay, B.C.
The actual cause of death is not yet certain, but it is likely
that the fetus died in the uterus, resulting in a necrotic
condition that eventually broke down the mother’s tissues,
according to Ken, founder of the Center for Whale Research. There
were no signs of trauma that would suggest injury of any kind, he
Dr. Stephen Raverty, a veterinary pathologist in charge of the
necropsy, removed J-32’s uterus with the intact fetus inside. Dr.
Rafferty told me that he plans to take images of the fetus in utero
tomorrow before continuing the examination. He said he would be
unable to provide any information until he receives approval from
his client, the Canadian Department of Fisheries and Oceans.
As in other post-mortem examinations of killer whales, experts
will examine tissues, blood and body fluids in multiple ways to
gauge the general health of the animal as well as the cause of
death. The Southern Resident pods — J, K and L — are known to carry
some of the highest loads of toxic chemicals of any marine mammals
in the world. The whales may also undergo nutritional stress
because of a shortage of their primary prey, chinook salmon.
The last sighting of the animal was Nov. 29. Her body was found
floating near Courtenay on Thursday, Dec. 4. She was a “remarkably
small” killer whale, about 15 feet long, Ken said. Females normally
grow to between 16 and 23 feet.
Rhapsody was born in 1996. Her mother, J-20 or Ewok, died when
she was 2 years old. The young whale was then raised by her Aunt,
J-22 or Oreo. Rhapsody is survived by her aunt and two cousins.
Orca Network’s news release about the death.)
At age 18, she was at the beginning of her reproductive life,
with a potential to add several babies to the dwindling population
of Southern Residents, now at 77 animals. J pod is down to 24
orcas, with only a few reproductive females at this time.
Ken Balcomb said he hopes Saturday’s necropsy will reveal
whether J-32 had ever been pregnant before, since killer whales
typically become fertile around age 12 and often give birth by age
15. Her mother was 13 when she was born, Ken noted.
When the ovaries expel an egg, it leaves a little white scar
tissue behind. If the egg is fertilized and grows, the scar tissue
is notably larger, Ken explained.
An average female gives birth every five years, Ken said. That
rate should be adding three or four calves to the Southern Resident
population each year.
“Three years ago, I predicted that they should be having 19
babies by now,” Ken said.
Instead, the population is declining, with no surviving calves
born last year or this year. A baby born to L-86 in September of
this year was reporting missing a little more than a month
Rhapsody was the third adult to die this year. Also missing and
presumed dead are L-53, a 37-year-old female known as Lulu, and
L-100, a 13-year-old male known as Indigo.
Howard Garrett and Susan Berta of
Orca Network may have spoken for many of us with this comment:
“We cannot express how tragic this loss is for this struggling,
precariously small, family of resident orcas of the Salish
Unmanned aerial vehicles, commonly called drones, could play an
increasing role in killer whale studies, according to Brad Hanson,
a researcher with NOAA’s Northwest Fisheries Science Center who has
been studying Puget Sound’s orcas for years.
Brad said a plan to use UAVs (he doesn’t like “drones”) has been
on the drawing board for several years. Unmanned aircraft can fly
over the whales far more cheaply than a full-size helicopter, which
has been used in the past. The small aircraft also may be able to
come in close for biological samples with less disturbance to the
whales than when operating from a research boat.
“I’ve been looking at this for a long time,” Brad told me. “We
have it in our (Endangered Species Act) permit to be able to use a
UAS (unmanned aircraft system).
Remote-controlled aircraft have been used by researchers to
study seals and penguins in the Arctic and to estimate their
populations with less disturbance than approaching the animals on
the ground. They’ve also been used to count birds in remote
In August, NOAA and Vancouver Aquarium researchers teamed up to
test the use of a remote-controlled hexacopter as they observed
Northern Resident killer whales in British Columbia. Mounted with a
high-resolution camera, the copter captured some amazing videos and
still pictures, including those on this page. See also
One can learn a lot from a good aerial view of a killer whale,
including general body condition, Brad told me. From a boat on the
water, it is often difficult to tell if an orca is healthy,
underweight or pregnant. From above, a whale’s girth is easier to
Researchers involved the British Columbia study — including John
Durban of NOAA’s Southwest Fisheries Science Center and Lance
Barrett-Lennard of Vancouver Aquarium — identified several females
who seemed to be pregnant.
They also spotted two whales that seemed emaciated. Those
animals later went missing and are presumed dead, confirming that
they were in poor health. What is not evident from photos, however,
is the cause of the problem, Brad Hanson said. Were the whales
suffering from disease, injury or another problem that caused them
to lose weight, or was it simply a lack of food?
Aerial photos also can be used to measure the length of a whale
and, over time, determine the growth rate at various periods in its
Brad said the ultimate goal is to develop health assessments for
the Southern Residents, listed as “endangered” under the federal
Endangered Species Act. A lot of technical details need to be
worked out, he said, but the plan is to use unmanned aircraft to
collect breath and fecal samples from the whales.
A breath sample is the next best thing to a blood sample, Brad
told me, and fecal samples provide information about stress
hormones, potential pathogens and other things.
“If you tied that in with imaging, we might be able to build
individual health profiles and begin to understand when something
is going wrong,” Hanson said.
Currently, breath samples are taken by driving a boat alongside
the whales and holding out a pole with an apparatus on the end.
Fecal samples are taken by following the whales and sifting feces
from the water.
If a small helicopter flown from a boat some distance away can
be used, the result would be less intrusive than a boat coming near
In the study in British Columbia, the general goal was to keep
the UAV at least 100 feet above the whales. The study also included
some closer movements to test the reaction of the whales. No
obvious changes in behavior were noticed, Brad said.
One permit still is needed for Hanson to operate a UAV in
Washington state. The Federal Aviation Administration must issue a
certificate of authorization, or COA, which spells out limitations
of the flight to avoid other aircraft operating in the area.
The Canadian experiment received similar permits from Fisheries
and Oceans Canada and Transport Canada. The aircraft was an APH-22
marine hexacopter built for NOAA by Aerial Imaging Solutions.
Ironically, amateurs in the United States are allowed to operate
unmanned aircraft in some areas without permits. But flying around
wildlife could create unanticipated problems for the animals. And
anyone operating around endangered whales could be in violation of
other state and federal laws — such as the Endangered Species Act
or Marine Mammal Protection Act — if they fly below 1,000 feet.
I’m on vacation this week, but I wanted to revisit a video I
first presented in June of last year. We see fishermen playing a
fish while a killer whale plays the fishermen. I interviewed the
excited man in this video soon after the fishing trip to explain
some of his comments. The video has now been viewed more than 1.2
Frank Sanders is an experienced hunting and fishing guide, yet
he screamed with excitement when he reeled in his fishing line to
find a killer whale at the other end.
The video, posted two weeks ago by Frank’s deckhand Charlie
Barberini, has been viewed more than 800,000 times on YouTube. That
doesn’t count the number of times people watched the original
post and videos copied from the original.
The video has raised numerous questions, such as why Frank is
showing his ring to the camera and looking for someone named Jason.
I was able to reach Frank in Hawaii, where he was on a fishing
trip, and he filled in some of the blanks.
Frank, Charlie and others were fishing for halibut near
Ninilchik in Cook Inlet in Southern Alaska. They had seen a couple
killer whales go by a few times but not close to the boat. I think
Frank told me the orcas were eating sockeye salmon that were in the
area. Suddenly, out of the depths, a killer whale appeared
following the fish on his line.
You need only to see and hear the video to know how much
excitement that generated.
Frank told me the orca did not appear to want the fish. It was
playing with the fishermen in the boat, grabbing the fish, pulling
the line out about 200 yards, then bringing it back. The whale
circled the boat a few times, he said, tangling fishing lines
played out from other poles. This went on for at least 10 minutes
before the whale went on his way.
The whale, of course, had the strength to bite the fish through
and take it away or snap the line any time he chose, Frank said.
But it didn’t.
About his ring, Frank explained that he travels a lot for his
business, Alaska Trophy Hunters. In fact, he is away from his wife
about as much as he is with her, so he sends her hunting and
fishing pictures from all over Alaska and displays his ring for
As for Jason, I didn’t get the full story, but I heard enough to
understand that this, too, was an inside message. Jason is Frank’s
best friend and the best man at his wedding. Jason was in a
four-wheeler accident and suffered a severe brain injury. He was in
a coma for a month but then was getting better. Jason set up a
personal website on “Caring Bridge” to share information back and
forth with his friends and family. Frank wanted Jason to understand
that he was thinking about him during this adventure and was
showing him a special bracelet they shared. Unfortunately, Jason
suffered a stroke and may not pull through. (Update, June 24,
11 a.m.: I just received word from Frank this morning that Jason
passed away yesterday.)
After the video was posted, Frank reportedly told reporter Lydia
Warren of London’s
“Fishing gets kind of repetitive after 18 years, but this is one
of the most exciting things that has happened to me.”
This week’s report about Puget Sound’s endangered killer whales
contained little new information, but the intent was not to
surprise people with important new findings.
The report (PDF 14.3 mb), published by the Northwest Fisheries
Science Center, was a nice summary of 10 years of research and
ongoing efforts to unlock the secrets of the mysterious Southern
NOAA also released the video, at right, which sums up the report
with great visuals. Make sure you go full-screen.
On Wednesday, I participated in a telephone conference call to
link reporters with killer whale experts in our region. On the line
were Lynne Barre, Mike Ford and Brad Hanson, all with NOAA
Fisheries out of Seattle. I’ve been wrapped up with other reporting
assignments, so the Kitsap Sun’s editors chose to run a solid story
by Associated Press reporter Phuong Le. See
Kitsap Sun, June 25.
Let me make a few quick observations:
Lynne Barre said one of the greatest mysteries,
to her, is why killer whales suddenly go missing. It’s a vexing
problem, and I always get a little nervous when the whales return
in the spring. One year, six of the Southern Residents failed to
show up. It was a real blow to the close-knit orca community and to
the struggling population, and I’ve never forgotten the dismay of
everyone who cared about these animals.
Healthy killer whales seem to go missing as often as elderly or
sick ones. Only a few bodies ever wash up on the beach. Even when
one is found, the cause of death often remains uncertain, as in the
case of L-112, found to have died of “blunt-force trauma” from some
Much more needs to be learned about disease in the animals,
Lynne said. Future research could involve more tissue biopsies and
breath samples in an effort to identify early signs of disease.
For Brad Hanson, another mystery is the whales’
seemingly unpredictable behavior and their “fundamental
relationship with prey.” We all assume that their primary goal in
life is to find fish to eat, but how good are they at this
essential task? Pretty good, I would guess. Often before we learn
that chinook are abundant off the Washington Coast, we find out
that the killer whales are already there.
Maybe the reason the whales have been spending so much time away
from Puget Sound the last couple years lies in the lower returns of
Fraser River chinook, which pass through the San Juan Islands in
the summer. Scale and fecal samples have shown that Fraser River
chinook are the most consistent prey of the resident orcas.
In previous conversations, Brad has told me that he would love
to communicate with the whales, to find out who is in charge and
why a group of animals may suddenly turn around and go in the
opposite direction. Howard Garrett of Orca Network recalls a time
when all three Southern Resident pods were in the Strait of Juan de
Fuca heading into Puget Sound. Suddenly K and L pod turned back,
while J pod continued on. Howie says it was as if they knew there
were not enough fish for the entire population, so J pod went on
alone, saying, “See ya later.”
Mike Ford wants to know why the population has
not increased more than it has. Could it be some limitation in the
ecosystem, such as the fact that other marine mammals — such as
seals and sea lions — have been increasing and taking a sizable
bite out of the available salmon population? We know that Northern
Residents, who also eat fish, don’t overlap territories much with
the Southern Residents. Living up north, the Northern Residents
have better access to some salmon stocks — including those that
originate in Puget Sound. If the Northern Residents get to them
first, the fish are not available for the Southern Residents — or
so goes one hypotheses. The Northern Resident population has
tripled in size, while the Southern Residents have stayed about the
Oddly enough, this potential competition for chinook salmon
reminds me of exactly what is taking place with regard to
commercial fishing enterprises. Washington fishermen complain that
the Canadians are taking salmon that should get back to Washington.
Canadian fishermen complain that Alaskans are taking salmon bound
for Canada. Only Alaskan fishermen — and those who go to Alaska to
fish — can catch a portion of the salmon going into Alaskan rivers
as well as some destined to travel south.
One of the new things that did come up in
Wednesday’s conference call was a renewed effort for U.S. killer
whale biologists and managers to work with their counterparts in
Canada. “We will be partnering with them on issues of salmon
fisheries and how that may affect the whales,” Lynn said, adding
that other cross-border efforts could involve vessel regulations
and targeted research efforts.
During Wednesday’s conference call, nobody talked about the
potential effects of military activities and the possible injury
from Navy sonar until a reporter brought up the issue. The question
was referred to NOAA Fisheries headquarters in Silver Spring, Md.,
where officials review the Navy’s operations and issue incidental
take permits. That was the end of that discussion.
I know the Navy is conducting research in an effort to reduce
harm to killer whales and other marine mammals. I get the sense,
however, that more could be done immediately if connections were
made between knowledgeable killer whale researchers in our region
