A twenty-two year study suggests that dolphins may form elite societies based on a learned cultural behavior that is shared with some but not all the dolphins in the pod. They exhibited a tendency to associate with those most like themselves, which is, scientists believe, a “critical role in human (sub)cultures,” and “may be true for dolphin society as well.”

Are Dolphins the 2nd Smartest Animal?
Scientists doing research on dolphin brains have discovered similarities with human brains. The new study, published in the latest Proceedings of the Royal Society B,
suggests that certain genetic features have led to the convergent evolution of
large brains and complex cognition in a handful of species, including dolphins
and humans.

Protection of Southern Resident Orcas Challenged
The Pacific Legal Foundation has challenged the endangered listing and protection of the Southern Resident pods saying that they are not genetically any different than any of the other thousands of orcas in the oceans and therefore do not deserve protection. They believe the Southern Residents are an "unjustified subspecies" of orcas and believe that NOAA invented a subspecies for the Pacific Northwest.

Death at Sea World
This article focuses on the author's view of what happened at Sea World in 2006 and 2010 when two orcas attacked their trainers killing one. There is a 15 minute video of the 2006 event. The orca had just been taken from her young calf and the calf was calling apparently greatly distressing the mother.

Crabbing Season Opens Today
Beachwatchers from the San Juan's were recently given an inservice by the Washington Department of Fish and Wildlife. Topics covered included recreational dungeness crab rules, ways to prevent crabs from being wasted and overfished and statistics on the rate of lost crab pots. Beachwatchers were asked to educate the public about the use of "rot cord" (which breaks down in the water and releases crabs when pots are lost), identification of male and female crabs (only males can be taken) and the legal keep size of 6 1/4 inches. The group was provided educational packages containing a pamplet, "Crabbing in Puget Sound" which covers this information in more detail, a caliper to measure crabs and a sample of rot cord to distribute to the public. The project is being well received by recreational crabbers.

Herring Return to Eastsound
For the second year in a row herring have spawned on the Eastsound waterfront. Volunteers from
the Indian Island Marine Health Observatory collected eggs over the Easter weekend. The herring are mainly spawnng on seaweed (sargassum) and dwarf eel grass both non-native species. Though not native to Fishing Bay these species are gradually creating dense thickets that herring
find attractive. It is not known whether there is any adverse impact to native species. Russel Barsh, Kwiaht ecogolgist, told volunteers "that as the Eastsound herring appear to be recovering this is the time to go gentle with Fishing Bay and Indian Island in order to give the herring and vegetation that supports them the best chance possible".

Procession of the Species Photos
A large group of spectacularly-garbed islanders paraded through Lopez Village last Saturday afternoon to celebrate the Island's second annual "Procession of the Species." From toddlers in strollers to septuagenarians, participants were clad in a wide range of imaginative costumes. The event, very ably-organized by Beach Watcher Charlie Behnke and Amanda Wedow, and sponsored by the Lopez Is. Conservation Corps and Lopez Is. Prevention Coalition, perpetuates a tradition begun over a decade ago in Olympia to honor our planet and all it's diverse species. A young turtle, who scooted the entire route on his tummy on a skateboard, some very busy bumblebees from Orcas, three different owls, a dragon, and many other feathered and furred creatures walked the parade route, accompanied by an assorted dozen percussionists, and it was fun for everyone. Pictured here are the huge owl (created and held up by Charlie and two helpers,) two very impressive Tufted Puffins, and a GMO ear of corn. The best moment of the afternoon happened before the parade when an invasive black slug (a.k.a. Nick Teague,) was lounging on the lawn, and a three-year-old boy sat down in front of him and began to feed him grass!

Proposed Ban on Flame Retardants Resurfaces in Legislature
A proposed ban on chemicals known as TRIS that are used as flame retardant used in children’s products resurfaced last week when the House General Government Appropriations and Oversight committee voted 7-6 in favor of House Bill 2821. The bill, prime-sponsored by Rep. Mary Lou Dickerson, D-Seattle, follows up on similar legislation that failed to pass during the regular session. Dickerson said she believes it has a chance of passing the Legislature now. However, the Association of Washington Business and other business groups continue to oppose it, arguing that a ban is premature, noting in part that one of the chemicals it seeks to ban has not been listed by officials as a chemical of “high concern to children.”

Following Varvara the Gray Whale
While "Flex's" transmitter fell off while he was along the Oregon coastline, Varvara's continues to transmit her travels. Flex managed to get as far as the Oregon coast before contact was lost in 2011. Varvara has traveled from Russia to the Baja and is now headed back to Sakhalin Is., Russia--her feeding grounds. She has not eaten in 5 months.

What Would You Do?
On a recent trip to the San Diego area, I enjoyed watching the sea lions who regularly haul out on along the waterfront in La Jolla. All day long people watch from the boardwalk above them as they warm up in the sun, compete for the more comfortable spots on the rocks, and swim and dive off the beach. I took a few pictures, including trying out the zoom on my new camera, but didn't look at them till I got back home and downloaded. To my dismay, I realized that the guy in the middle of this picture has a bunch of netting of some kind around his head. (It's more evident if the photo is enlarged, but it's definitely there.) I couldn't tell exactly what it is, or how badly entangled he is, but he seems to be stuck with it. What do you do? I passed the picture along to the Whale Museum, hoping they might have some contacts in the La Jolla area, but is there even any way he could be helped? It's very hard to see things like this and feel like there is not much that can be done. Certainly a sad reminder to all of us that everything we put into our waters has an impact. I hope this guy has been able to extricate himself and that he'll be able to avoid similar encounters in the future! Susan

Are Whales People, too?
At the recent meeting of the American Association for the Advancement of Science (AAAS ) held in Vancouver, BC, one topic discussed by scientists was whether whales and dolphins should have rights that are currently only given to humans. Kari Koski, The Whale Museum, spoke about the Southern Residents as being given some "rights" because they have been declared endangered. Because whale and dolphin brains are on a proportionate scale with the size of their bodies (as are humans), they have developed hunting strategies, and have unique communications among pod members as well as a complex cultural structure, some scientists argued these were reasons to give them some moral rights.

Herring Importance Noted at Annual "SALMONATION" Celebration on Lopez
Lopez residents gathered once again at the Community Center on Jan 21 for an evening of food and fun that accompanied Kwaiht's annual report on the previous summer's salmon seining at Watmough Bight. Volunteers gather salmon and other fish in a net every other week, and then quickly measure, count and examine them, mostly the chinook, before releasing them back into the water. A small DNA sample is taken, and seasoned volunteers also collect the stomach contents of the fish, which are later analyzed at a lab. During the several summers this research has been going on, (both at Watmough and at Cowlitz Bay on Waldron,) the data accumulated has indicated interesting trends in the diet of the salmon.
Chinook seem to prefer smaller fish as their primary source of food, as these provide the largest "bang for the buck" from a nutritional standpoint. If not enough fish are available, crab larvae are their next choice, with insects filling the gaps. In previous summers, sandlance have been the most common fish eaten, but in 2011, the chinook consumed large quantities of herring. According to Kwiaht's Russel Barsh who presented this annual report, the chinook arrived earlier in the season while the herring - thicker in girth than the sandlance - were still small enough for the herring to consume. When the salmon arrive later, or the herring are bigger, they have to be content with sandlance.
Russel pointed out that most forage fish restoration in the islands is currently focused on smelt and sandlance, with virtually no emphasis on herring. Based on the most recent survey results, he feels that it is important to give much more thought to how herring spawning could be increased in the Islands. The largest herring-spawning grounds in the Salish Sea are off Cherry Point (another reason to be actively involved in the coal terminal plans!) But by the time those herring find their way to the Islands in the summer, they may be too big for the chinook.
Death of Sooke (L112) Confirmed
On Feb. 11, 2012, a stranded killer whale washed up just north of Long Beach, Wash. Photographs of the dorsal fin and saddle patch were matched to catalogs of known killer whales by biologists from NOAA Fisheries and the Center for Whale Research. The whale has been identified as a member of the Southern Resident L Pod known as L112, a female calf of L86. A full necropsy was conducted on Feb. 12.
Samples were taken for a variety of analyses. Processing of samples could take several weeks or months, and will hopefully provide insight into the origin of the traumatic injuries or other factors that may have contributed to the death of this whale. More information is available on the Cascadia Research website at:
http://www.cascadiaresearch.org/examination_of_dead_killer_whale-12Feb2012.htm
In November a killer whale calf stranded on the Washington coast on Nov. 14, 2011. A genetics sample was taken and the female calf has been confirmed as an eastern North Pacific offshore. A congenital defect was determined to be the cause of death in this case.

Ways of the Whales Workshop Recap
Over 200 people attended the Ways of the Whales Workshop in Coupeville in January -- the largest attendance ever. This particular workshop focused on the research being done on behalf of the Southern Resident Killer Whales (SRKWs) and was a wonderful opportunity to hear the results. I have included links so that you can read further.
Howard Garrett, Orca Network, began the morning with a history of orca captures and current captivity. On average, the orcas in captivity live about 8.3 years. More aggressive behavior is being seen in captive orcas. The Orca Project http://theorcaproject.wordpress.com/ raises awareness of captive orcas.
Candice Emmons, NOAA Fisheries NW Fisheries Science Center, Seattle, WA
www.nwfsc.noaa.gov/research/divisions/cbd/marine_mammal/marinemammal.cfm discussed the research resulting from the DTAGs used on the SRKWs. The tags consist of acoustic and depth sensors. The data will be used to discover what physiological effects result from sound exposure primarily from large ships. The sound level is recorded, as well as the whales’ reactions to the sounds – whether they dive deeper or stop or change their behavior. These tags are a suction type that stay on for approximately 3 to 7 hours. No location data is received from these tags. To date 14 SRKWs have been tagged. This research is part of the SRKWs recovery plan developed by NOAA.
Matt Krogh and Lindsay Taylor, North Sound Baykeeper Team, www.re-sources.org spoke of the proposed Cherry Point coal terminal. Since you have received a separate email on this, I will not elaborate further.
Jessica Lundin, Center for Conservation Biology, Univ. of Washington, http://conservationbiology.net/research-programs/killer-whales-2/ discussed her research on the SRKWs using fecal sampling. Specially trained scat detection dogs, in this case “Tucker,” are used to find whale scat. Tucker was on the Westside of San Juan all summer – sniffing away! From the feces, data is collected on DNA, hormones, diet, immunoglobulin, pathogens and the SRKWs’ exposure to toxins, metals and pesticides. In addition, the feces can also show pregnancy. DNA samples have been collected on 60% of the SRKWs.
It was interesting to note that the hormone testing revealed that when the SRKWs arrive in the early spring they are at their highest nutritional level and consequently the stress hormone level is the lowest. As the summer progresses the stress hormone level goes up or down depending on prey abundance. However, by the fall they are experiencing more stress. Her findings revealed that prey availability has more effect than boat traffic. Stress levels around boats were short term vs. long term if a lack of prey. She believes the threats to the SRKWs are 1) decreased prey, 2) excessive exposure to contaminants, 3) increased boat traffic, and 4) oil spills. In addition, she believes the availability of spring prey is very important.
Toxin levels in J and L pods were sampled. DDT was twice as evident in L pod whales vs. J pod. PCB levels were high in both pods. PBDE levels (flame retardants) were high in L, less in J. Chlorinated pesticides (lawn products) were high in both pods.

Indian Island Low Tide Evening Walk on January 23, 2012.
A scheduled January 22nd low tide walk did not take place due winds pushing the tide onto the tombolo. Those who showed up were not able to get out to Indian Island. The next evening Beach Watcher Nancy Alboucq and her husband, Steve were able to wade out to the island. They spent an hour exploring and taking photographs including the one below. They reported that on the far rocks the frosted dirona's were putting on a beautiful show and saw about a dozen of them. They also saw many porcelain crabs, gunnels (and what they believed were gunnel egg clusters), kelp crabs, barnacle nudibranch with egg ribbons, and hundreds of tiny shrimp with their eyes glowing in the tide pools and shallow water around the island.
The next time the island will be accessible is on April 8th. This is also the date of a scheduled invertebrate survey. Hope to see you out there.
