Steps walked: Shaun - 8,281, 32 stairs climbed; Shannon - 6,941, 32 stairs climbed
Critter count: 4 adults male orcas, a mother and calf orca, and about 10 juvenile male orcas (and I do mean juvenile), maybe 20 humpbacks including a mama and a baby, 2 juvenile bald eagles, a shitload of pink salmon, several sea otters, and bear scat but no bears
We all went racing onto the deck to see the orcas, and at that point, basically all hell broke loose. For the next 2 hours we were entertained by a mixture of humpbacks and orcas that was so extraordinary, even the naturalists were agog. No one knew where to look because they were frickin' everywhere! There was a group of males who played and flapped and flipped and spy-hopped and climbed all over each other. There were 4 HUGE males who kept their distance at first but then came in to see what the heck was going on. The humpbacks were right in with the orcas and were not in distress at all. This group (or groups) of orcas were resident orcas who eat fish, so they were no threat to the humpbacks who seemed to know this because they were just one big happy mess of marine mammals. Even the sea otters we saw a little later were not concerned when several of the orcas swam right by them. As a naturalist noted, the other kind of orcas are called transient orcas, and they eat mammals, including baby humpbacks, which is how we knew that these orcas were residents because the humpbacks would have beat feet away from them for sure.
Another interesting phenomenon we witnessed was what the naturalists call a "Pink Floyd" which is an erect orca penis that we were treated to several times during our morning commune. Naturally, I was very interested in this phenomenon being a connoisseur of all forms of male genitalia, but unfortunately, I never got to see it (despite my running all the way to the lounge to get stronger binoculars!). Shannon thought she caught a picture of it, but we can't find it now, so bummer for you!
So....eventually the whales moved on, and we all went inside to warm up. The ship moved towards Peril Strait which is a long, twisty waterway between the ABC islands of Admiralty, Baranof, and Chichagof. About 30 minutes later, Cindy announced that we had another delay....I'm thinking we're having technical problems with the ship...but no....there's more dang orcas! This time it's a mama and a baby and another female. Holy crap, seriously? Some people were very blasé this time, though, and didn't bother to go out on deck. I said to heck with them and went out and had more orca fun, cuz let's face it...this is what we came to Alaska to see, and I was going to milk it for all it was worth. There were a few more humpbacks in the mix, and then we got close to a couple of islands...one where sea otters were hanging out and another where Stellar sea lions were sunning on the beach. It was weird because the orcas swam very close to the otters, and neither of them bothered the other in the least.
Before lunch, we were treated to a presentation by Rich (the photographer) about one of his passions, time lapse photography. It was totally over my head, but it was still interesting to see his work, and he is helping many conservation organizations by providing visual proof of various problems that need to be addressed in the naturalists' world.
After lunch, we were treated to ANOTHER presentation by Andy, the head of the Alaska Whale Foundation who was also a professor at a couple of universities and a sponsor of graduate students. He had a whole bunch of other credentials too, but the most important thing about Andy to Shannon and me was that he is an expert on all aspects of humpback whales...especially their feeding habits. This guys was SMART with a capital S and a super good speaker. He was also very cute, too, so we had a very enjoyable hour listening to him talk about the various marine mammals in the area.
Once he got to the humpback whales, though, you could just feel his passion, and we learned all about the Pacific Northwestern whale population. These animals are unique in all the world because 95% of them winter and breed in Hawaii exclusively. They only breed with other Hawaiian whales and keep the gene pool very clean. However, there is nothing to eat in Hawaii (crazy huh?), so for 5 months the females take in no nourishment at all despite the fact that they are nursing their calves during that time and traveling so far. They lose a third of their body weight during that time, which is why they're so hungry when they get back to Alaska. Thank goodness the waters here are so rich in food for them!
Pacific Northwestern whales also exhibit some interesting feeding adaptations, one of which is called bubble net feeding. In bubble net feeding, one whale goes way below the surface and blows a ring of bubbles around a school of herrings. Another whale emits a very distinct sound that scares the herring, and between these 2 behaviors, the herring stay within the net and don't swim below it or in between the bubbles. The other whales in the group (which can be between 2 and 24 animals but are usually 8-10 individuals) come up from underneath the net and gulp 12 telephone booths worth of water and herring into their mouth (Shannon and I don't remember the number of gallons). They strain all the water out and are left with only the herring. If you want to see it in action, go to YouTube. There are some great videos showing the phenomenon.
It turns out that, of the 20,000 humpbacks in the Pacific Northwest, only 50 or 60 of them practice bubble net feeding, and of that group, only 6 or 7 do the actual netting and vocalizing. Also, the 6 or 7 specialists, as they're called, usually work with the same partner through the years, and these whales live to be upwards of 100 years old! The partners are not necessarily related to each other, and it doesn't appear that they teach their skill to their children either. They think the specialists just learn by trial and error after having been in a bubble netting group that loses their specialists.
Another interesting feeding adaptation of whales in this area is used by sperm whales, which never used to come to this area, but about 13 years ago, a couple of whales came into the Inside Passage and figured out that the long line fishermen had halibut and black cod attached to their fishing lines. The whales will find a long line boat and sleep by it until the boat's wench starts up and then they proceed to pluck every one of the fish off the line! Can you imagine? The fishermen have no recourse but to just pack up and leave because there's nothing you can do to make a sperm whale move on if he doesn't wanna.
(How do you like my alien baby?)
Well, that's about it for this wonderful day in Chatham Strait and the ABC Islands of Alaska. As far as I'm concerned, there's nothing that could possibly beat this day....but I'm willing to let Lindblad/National Geographic give it the old college try!
And one last whale picture:
