    First some sad news, then some happy news.

    Sad news: an orca stranded in South Africa died despite attempts to help her. Researchers examining the dead whale found various plastic and other garbage items in her stomach.

    Happy news: another new SRKW calf! This one is once again from J-pod. The mother is J-28 Polaris. She had been looking kind of fat the past few months so she was suspected of being pregnant. She is 22 years old and has one other calf, J-46 Star, born in 2009. It seems these whales have discovered that one trick fertility doctors don't want you to know.

    Rare Killer Whale Dies After Becoming Entangled in Fishing Gear

    A killer whale from the West Coast population, Lulu, washed up on shore dead. Researchers determined that entanglement was the likely cause of her death. The West Coast population hasn't produced a calf since 1992, making it likely that the 8 whales left will be the last of this distinctive group. Researchers are hoping that information and samples taken from the necropsy will provide new information about this little-known population, such as pollutants, reproductive status, and age.

    An article that details recent observations of "catch sharing" between related Northern Residents. Even a single fish might be shared with a relative, this may be a way of increasing fitness for the whole pod:

    Also, a fascinating story about how salmon conservation in Idaho might be the solution to some of the Southern Residents problems:

    It's where all the cool kids gather. I bet it would be very cool to see.

    A number of Australian orcas seem to have that interesting eyepatch shape. Is that unique to the region? I'm trying to remember if I've seen it with others.

    Cool! I do love hearing about individual orca populations, it's so interesting how they're all a little (or a lot) different. Personally I hope that there will be more research into tropical populations sometime soon.

    Toxins may be causing more male killer whale births, says researcher | Toronto Star

    J54 is confirmed to be male. Of the eight calves that have been a part of the Southern Resident baby boom, only one has been confirmed to be female. Five, including J54, are confirmed to be male. This is troubling for a struggling population. Researchers believe that toxins in the water are causing the skewed gender ratio.

    Also, a dead female orca calf was found near Sooke Point. Researchers will work to determine the ecotype and cause of death. Because of its small size, it's not likely to be a SRKW that we know.

    Lots of Southern Resident news today, most of it sad.

    2 orcas found dead in B.C. waters part of endangered population | CTV Vancouver Island News

    A dead orca found near Vancouver has been identified as 20 year old SR male L95 "Nigel".

    The dead female calf found a few weeks ago has been confirmed as an SRKW. The calf was estimated to be about two weeks old. Researchers have yet to determine the cause of death for either of the whales, though they suspect the calf died due to birthing complications. All terribly sad, though I am glad that at least the bodies washed up so necropsies could be performed.

    Finally, J53, one of the newer SR calves has been identified as female. Hopefully she'll reach adulthood and produce some calves, as the population could really use more females right now.
