L90 Update: September 11, 2011

L90:
We have been episodically monitoring L90 - taking respiration rates, surfacing/ 

dive intervals/traveling speed, and videotaping , as well as taking good-quality close-up photos of her melon, etc. 

She continues to consistently trail the other whales and  is breathing at frequent intervals ranging from 20 sec-120 sec, with  

most in 30 second range. Her dives are typically shallow (often visible underwater at about 60'), and when observed the in calm water near East Point on September 20th, she was making brief  vocalizations between breaths. At the time, she was lagging behind the other whales by about one and a half miles. Her surfacing posture  is unusual - when logging she "bobs" for each breath, and when traveling she surfaces horizontally and then dives rather  "stiffly", as if there is a problem with her spine. She has been doing this since July 6, before the alleged vessel strike. 

We recently noted her surfacing about 100 feet behind a yacht wake  and she appeared to be thrown off balance from the wake. She was also observed rolling on her side going through kelp. She does not show evidence any emaciation. The most notable aspect of all of this, and it is also notable for other ailing/trailing whales we have monitored in the past: there is little to no obvious care-giving behavior exhibited by the other whales. Presumably she is eating, otherwise she would show evidence of emaciation.  

We all have concerns for the fate of this whale, but there is very little that anyone can do but observe. This has happened before, and it will happen again.

L90 Update

After the alleged vessel strike last week and the recent unusual behavior displayed by female killer whale, L90, the Center for Whale Research staff had an an opportunity to further observe her condition on Saturday September 3rd.  This was the first time she had been seen since the incident. The following is a summery of that encounter:


"After receiving a report of whales on the west side of San Juan Island in the early morning, Center staff cast off from Snug Harbor in vessel Orca at 8:15 a.m. and found members of J,K, and L pods heading north in Haro Strait off Limekiln lighthouse at 8:25 a.m., spread out in singles and groups. The main mission of the day was to find L90 and monitor her health and behavior, so we moved from group to group trying to locate her.
Around 9:15 a.m., we found L90’s main traveling companions, L26 and L92, in the proximity of J pod members near Kelp Reef, moving rapidly north in Haro Strait. About a half-mile to the southeast of this group at 9:33 a.m., we found L90 traveling north by herself at slow to medium speed.  She was trailing the other whales by as much as 3/4 mile and never less than 200 yards.  We collected respiration data on L90 for two periods from 9:40-10:46 a.m. and 1243-1342 a.m., during which times she was breathing regularly at intervals averaging 33.6 seconds and 29.9 seconds, respectively. Meanwhile, the rest of the whales traveled north in Haro Strait, and then northeast into Boundary Pass. During these two data recording periods, L90 only made one “long” dive of 180 seconds which was immediately followed by her shortest recorded dive of 8 seconds.  Her swimming speed was 4.4 and 4.6 knots, respectively, during the data recording periods.

When sea conditions and proximity allowed proper observations, it was apparent that L90 was not diving deeply and her surfacing motion seemed stiff – often with more of her back behind the dorsal fin exposed than a healthy whale would have exposed on a normal surfacing.  However, she showed no visible signs of emaciation and did not have foul smelling breath, two common indicators of illness. Based on our observations it is clear that her behavior is abnormal, however the cause remains unknown.

Around 2:15 p.m., as the leading whales picked up speed near East Point, L90 also increased speed and caught up to the other whales just north of East Point. She joined with L26 and L92, and the three traveled rapidly (>7 knots) NNW toward Point Roberts amidst other loosely spread, rapidly moving, mixed groups of southern residents. We ended the encounter at 2:51 p.m. approximately 3 miles north of East Point."

L90 was again encountered the following day, September 4th, and appeared to exhibit the same behavior. We will be taking every opportunity to continue to observe L90's condition and will provide subsequent reports.

L90's Alleged Vessel Strike

The Center for Whale Research received a report this morning of a potential vessel strike with a southern resident killer whale. The whale that was believed to be struck is L90, an 18 year old female. Witnesses described the whale logging, or floating at the surface, for a prolonged period after a private vessel was observed passing very close to where the whale was thought to be. L90 was then reported to remain on the surface and was breathing heavily. Once we received the report we quickly departed and found L90 with her mother, L26 just off Lime Kiln State Park. She was moving slowly and spending several minutes resting at the surface. She was taking shallow dives and barely moving north with the rest of the whales. We were able to observe her very closely and found no evidence of a vessel strike. On numerous occasions she spent several minutes hovering just below the surface of the water allowing us to get a good look at most of her body, and we did not see any wounds or scratches. We continued to follow her for a few hours and observed that she eventually began to travel at a more normal pace, although remaining behind the rest of the groups of whales. The other whales in the area were behaving normally, resting, foraging and socializing. Based on our observations and descriptions of the event from witnesses, we do not believe that L90 was struck by the vessel. Based on her age and previous behavior we have concluded that she may be pregnant. It is also possible that she may be ill or have some unknown condition.

On several encounters this summer, we have noticed L90 traveling slowly by herself in a rather “mopey” manner. L90 has always been a “whale of concern” to those of us that see her frequently. She is a noticeably a small animal compared to other females who have reached reproductive age.

Additionally, there seems to be something unusual about L90’s body condition. Her body shape is different from every other whale in the L26 matriline. She appears to have a kind of a two-lobed swelling behind the blowhole and a slight arch to her spine in front of the dorsal fin. Whether this swelling is just excess blubber or a sign of illness, we do not know. The only other whale who has been seen with a similar looking swelling behind the blowhole was L107, a calf born in 2005 who did not survive its first summer. It is certainly a different look from the emaciated “peanuthead” look that we have previously seen in several whales who subsequently died.

The slow moving and logging behavior she exhibited today and yesterday may be a sign of that she is in labor and therefore very tierd. She is a whale that we would expect to have a calf at any time since she has passed the age when most females have had their first calf ( about age 14). Although we have no concrete information to support this, we do have concerns that her small body size may make for a complicated pregnancy and birth. Labor pains or a difficult pregnancy could explain her behavior.

The other possibility, that she is ill, is supported by previous observations in other animals. In the summer of 2008 L67(deceased) was observed floating for prolonged periods at the surface before she showed any signs of the emaciated condition that proceeded her death. Therefore L90 could also be showing signs of distress due to an unknown illness.

With respect to today's event, we suspect she may have been laying on or near the surface already when the vessel passed close by, but most likely missed her. It is very difficult to determine distances between vessels or between whales and vessels from the water level. Therefore she may have appeared closer to the vessel than she was.

In any case, we will continue to observe L90 over the next few days. Our hope is that the next time we see her she is traveling with a healthy new born calf.

Southern Resident Orca Population Status (With Notes On J-1)

2010 ended well for the Southern Residents.  The total population as of December 31^st was 87 individuals: 27 in J pod, 19 in K pod and 41 in L pod.  By the end of the year, 5 of the 6 calves born in 2010 were alive and healthy.  We had one edition to J pod, J47 (calf of J17); one edition to K pod, K43 (calf of K12); and 3 in L pod, L115 (calf of L47), L116 (calf of L86), and L117 (mother unknown).

So far 2011 has been full of sightings and encounters.  J’s, K’s and L87 have been seen often in Haro Strait and Puget Sound.  They were first encountered by the Center on January 3^rd in Haro Strait, then again on the 7^th.  J’s and K’s were also encountered in Haro Strait and San Juan Channel on the 23^rd and 26^th  respectively.  Residents were sighted at least once a week throughout January (eight confirmed sightings in all). February has been even better with almost daily sightings of J’s and K’s in Puget Sound (eight sightings since Feb. 20^th)

There was a possible sighting of L pod on January 15^th. Most likely the L12’s, but because of the distant photos we can’t say for sure.  Ken encountered L pod spread out and foraging off Monterey Bay on February 10^th.  There have been several killer whale sightings on the west coast of Oregon and California this winter, but no other southern resident sightings have been confirmed. 

No new calves have yet been seen in 2011.  It is still too early in the year to have an official population estimate as not all individuals have been accounted for.  However, there have been several encounters and sightings of J pod where J1 has not been seen or photographed.  

 J1 is the oldest male in the southern resident community, estimated to be 60 years old.  He is an iconic figure for the entire population and by far the most easily identifiable whale.  His tall wavy fin has given him the name “Ruffles” and made him a favorite among visitors and local whale enthusiasts.   He was last seen on November 21^st off Victoria. 

Although there have been several encounters with J’s over the past few months, the pod configuration has been spread out and all individuals were not photographed.  Although J1 is most often seen in the presence of J2, the eldest female in J pod, he is frequently sighted off on his own far away from the rest of the pod.   

 At this point all we can say is that J1 is officially missing.  We will be keeping an eye out for him as we head into spring and encounters and sightings increase.

Baby Killer Whales, Their ID Numbers, Their Names, And Their Parentage

Ken Balcomb, CWR founder.

By K.C. Balcomb

 22 August 2010

            The Southern Resident Killer Whale (SRKW) population underwent a genetic bottleneck sometime between one and two-and-a-half whale generations ago that has resulted in a very small and fragile effective population size – only about 25 whales currently parent any offspring, while the remaining 60 or so whales are either too old or too young to contribute to population growth. That fact alone makes every baby whale precious, or at least it should be precious, to everyone on this planet that cares about the survival of these charismatic icons of the Pacific Northwest. Being born is one thing, surviving in the modern world is another. 

          My goal is to encourage our human society to make it possible for the effective population size of SRKW’s to grow during the current generation, and for the foreseeable future. Too often, for too long, and too recently we have seen it decline. In order to see increase we must give priority to allowing the whales sufficient food = salmon to survive, year-round, and that amounts to a lot of fish.

           At the risk of designating a baby whale an ID number or a name when there is a good chance that it will not survive, and thereby perhaps offending some and wasting numbers, I am going to exercise my prerogative and name a few:

Star

            In J pod, there was a new calf born in November 2009 to a sixteen-year old new mother designated J28. I earlier designated the new female calf J46 and called her “Star” for the starring role I hoped she would play in inspiring the public interested in conserving the fish resources needed for the entire SRKW population (and for humans).

Looker

            

 Also born into J pod in January 2010 was another new calf, this time a young male whose very young mother is twelve-year old J35. I designated this new male calf J47, and now call it “Looker” because it frequently (and delightfully) raises its head high above the water as if looking around when swimming alongside its mother.

            

Speedy

 In K pod, there was a new calf first seen in February 2010 with an experienced mother K12, who is also a grandmother. Virtually every time we see and photograph this new rambunctious baby whale it is racing alongside its mother, so I have called it “Speedy” and have designated it K43 - the newest member of slow-growing K pod.

Hope

           

 In L pod, a new calf appeared in the summer of 2010, itself an unusual event because most new SRKW’s are born in winter months. The births typically occur in mid-winter seventeen months after the party times of historically abundant summer salmon migrations to these inland marine waters. 

          Conception of this new calf, designated L115, must have occurred around January or February 2009 when all three pods made an unprecedented mid-winter appearance off Victoria (see Encounter 3, 2009 CWR webpage). The mother is L47, who has lost her previous four consecutive babies (L99,L102,L107,L111) since giving birth to her two successful daughters (L83 and L91), in 1990 and 1995. Without yet knowing the sex of L115 the newest calf of L47, I am going to call it “Hope”, for obvious reasons. “Toast” was submitted, but it is not very optimistic for a whale name when we hope it survives.

           

Molly

    

        L113 was born in the autumn of 2009 to fourteen-year old first time mother L94, and she is healthy and doing well as of this writing in late summer 2010. This year has been a relatively good year for salmon in the local waters, so we are wishing all is well for her. I am going to call her “Molly” after a very good friend whose ashes were spread as L113 and her extended family swam nearby in Haro Strait this summer.

            

Victoria

 Two other recent L pod calves are worthy of mention: L112 born to L86, probably in January 2009 and first documented in the afore-mentioned Encounter 3 of 2009 when she was less than a month old; I am going to call her “Victoria” for the beautiful city waterfront where she was first seen. [Hold your nose until the sewage issue is resolved! Maybe we should call her “Stinker”?]

Flapper

And, last but not least, we have L110, a very rambunctious young male born to a young mother, L83 first daughter of L47. We first saw him in August 2007, still showing evidence of fetal folds from recent birth; but, by October he had clear evidence of a mark that will no doubt remain with him for the rest of his life: a large flap of his upper right lip had been torn askew and was protruding awkwardly from the starboard side of his face, perhaps from an encounter with the steel leader of a fishing line. He also now has evidence of a bulbous tooth abscess just in front of the flap. I am going to call him “Flapper”, in anticipation that a bit of Aussie humor will be good for him. He probably does not mind his easily remembered name, though others might.

            My apologies to those who may be offended by the names and numbers I have given these whales. I’ve given the subject a fair amount of thought over three decades, and have refrained from giving them meaningless, stupid, or unpronounceable names. You may call them anything you wish, but I have been keeping the official records of these whales from the beginning of their study, and these names and numbers are what we will write in our books. The paternity paper is in preparation and due out soon; and it is likely to be at least as interesting reading, if not downright scandalous. Here’s a little teaser: the whales apparently live up to the motto: “Old Guys Rule” and you can guess what that is about.

            We will discuss the reasons for the SRKW population bottleneck in another writing. Meanwhile, do whatever you can to promote healthy wild salmon populations, particularly Chinook salmon, in the Pacific Northwest if you would like these babies and the SRKW population to survive.

           

R.I.P., L114

  Another new calf in L pod, L114 born to L 77, first appeared in February 2010, but it did not survive to summer. No name, but only a number for its tombstone in our records. (see Matriline guide on our website).

The Orca Calf 'Star' Continues To Shine

Eight month old orca calf 'Star'

Last November, when this calf was born the Center for Whale Research broke from custom and gave the baby the name 'Star' in addition to assigning it the usual number (J-46, 'J' for its family pod, and '46' for the fact that it is the 46th J pod member identified):

The new baby is designated J46, and we are going to call it "Star", for the role that it will play in showing the human inhabitants in this region that it is important to clean up Puget Sound and restore healthy abundant salmon populations to the Pacific Northwest. That mission brings a message to all of the relevant human nations – USA, Canada, First Nations, Treaty, and non-Treaty – that the first intelligent mammal residents of the region are also investing in these efforts. We could not ask for a more charismatic indicator, a baby whale, to measure the success of our renewed efforts for restoration.

J pod is the most watched family of whales in the Pacific Northwest, or perhaps in the world; and, this is the first year in recent decades that they have produced three babies within one year. We will all be watching, here and worldwide, carefully and respectfully, to see if they beat the odds and all survive. This is the reality show that really means something.

'Star' at two months old.

All of the J-pod calves born last year look healthy, and if you look carefully at the picture below you will see all three of the calves together with Star's mom and grandmother, the calves no doubt enjoying some play time together.

'Star' swimming with mom J-28, grandmother J-17, uncle J-44 and cousin J-47

So far, Star's future is shining brightly, as people continue to increase efforts to restore Chinook salmon populations and modify commercial fisheries. This little whale is indeed an icon of humanity's progress, and we'll keep an eye on this Star and report her progress as time goes on.
