Summary for November 22 2019 Bigg’s The day started with another amazing sunrise, with nuances from yellow to pink painted in the sky. And like the last few days, the sea was calm, so were its inhabitants. Jérémie went to help Mike in Telegraph Cove for a few hours and on their way back, with the tide changing the weather changed too. The south eastern winds started to blow and the rain was back by midday. There were no sea lions on Sea Lion Rock today, maybe they are getting used to the new camera stand over there. By 5:23pm, we were surprised to hear calls on our Parson Island hydrophone, even more surprised to be hesitant about who those calls belonged to. First, we thought a humpback whale was having a fairly unique recital, but when we noticed more than one individual at 5:39 pm, followed by sounds similar to echolocation at 5:41 pm, we corrected our thinking, Bigg’s orcas! The calls were beautiful and unique, it almost felt like there was some imitation of humpbacks whistles and sometimes even Resident calls. The Bigg’s were getting closer to Parson Island and made beautiful calls at 6:03pm. They travelled further into Blackney Pass as they reached our local left hydrophone by 6:34pm, and stayed around for an hour and a half calling continually. Was there a sea lion hunt going on? Unfortunately, it was completely dark and choppy out there so we were not able to see or even hear any blows outside the lab. The Bigg’s were very vocal and close to the hydrophone between 6:50pm and 7:43pm. Then, they eventually headed south again, passing very close to our Parson Island hydrophone at 8:00pm. The group of orcas travelled into Johnstone Strait and headed east, possibly along the Cracroft Island shore towards our hydrophone located in the Robson Bight Ecological Reserve. Their calls were sporadic but with a few close calls at 11:40pm and 12:48am on the morning of the 23rd. We last heard them at 2:48am! It had been a week since we last heard orca calls on our hydrophones. So today was an amazing day, listening to these incredible Bigg’s calls for more than 8 hours!

Summary for November 20, 21 2019 The last couple of days have been pretty sunny and chilling at OrcaLab. We are still scanning the calm sea for any kind of blows, but despite the pleasant sunny weather, it really feels like we have entered a new season. Without the humpbacks and orcas around all the time, our attention is more and more focused on birds and sea lions. Mergansers and harlequin ducks are common visitors as well as the great blue heron and bald eagles watching for any food opportunities. We could see and hear the sea lions as usual, 10 hauled out on Parson Island shore and 31 on one of their favorite spots, Sea Lion Rock. Speaking of which, it is time to put the Sea Lion Rock camera back in place! And in order to do so we spent the day of the 20th to think about a plan and prepare the gear and material for the next day. On the 21st, Claire heard a very brief humpback call at 2:30am and then another one at 5am but as soon as she entered the lab, the whale stayed silent. With the amazing morning light, Matchu and Mike from Double Bay, came to help Paul, Claire and Jérémie to set the new Sea Lion Rock camera stand, a big thick piece of log, that will now hold the camera at its very end. This was the inspiration of Matchu now necessary after the original camera metal stand was literally destroyed when some of the 2000 pound sea lions leaned on it. Later on, after an intense and physical effort, the log was set in place and the camera back on a live stream! It took almost the full day but this was a great job done. There is still work to do over there (set microphone back in, level the camera, connect the underwater camera... but this is another story for another day.
