Superb sounds!!
Two humpbacks warming up in Johnstone Strait! One on our hydrophone in Robson Bight, the other near Cracroft Point. Suzie 24 Oct 2019 22:29:16 PST
Summary for October 23 2019 A34s, A42s, Humpbacks (Backsplash) An early start on the 23rd with some distant A34 calls at 2:10am on the Robson Bight hydrophone with the whales were back in Johnstone Strait. Their conversation was brief, wrapping up by 2.33am. Perhaps they fell silent to listen to the humpback, who also started vocalizing in the Strait at 2.19am? He took center stage and we were treated to yet another beautiful, clear song - until the orcas chirped up again at 3:09am this time off Cracroft Point! The humpback and the orcas spoke in tandem for the next few hours in the Strait, each melody rising and falling as if to allow the other to speak. At 5:26am the humpback had the final word, and the waters fell quiet until the dawn. The day broke with the most glorious sunrise, and as the last pinky hues faded we heard A34 and A42 calls off Cracroft Point at 8:14am. Not long after, at 8:30am, we spotted them on our remote camera at CP foraging in the “rip” off Blackney Pass - a favourite spot of theirs. We saw at least five smaller fins, with a large adult male and sprouting male in the mix. Their calls were infrequent over the course of the morning, bouncing between Robson Bight and Cracroft Point hydrophones as they moved west in Johnstone Strait and on toward Weynton Pass. Blackney Pass was a miss this time. By 12:19pm, some of the A42s had made it into Blackfish Sound, as we started hearing their faint calls there. Their calls remained very distant for a while, and we last heard them at 2:09pm in the Sound. It was, however, a very busy day in Blackney Pass for humpback whales with several individuals foraging in our view, and we identified “Backsplash” fluke slapping near Whitebeach Passage at 1:43pm. The rest of the afternoon was relatively quiet - perhaps in preparation for the excitement the night was to bring! Just before 8pm we heard a humpback “warming up” his vocal chords in Johnstone Strait. Within a few minutes he was making some excellent sounds, and must have attracted someone’s attention as a second humpback joined in for a duet at 8:13pm, also in the Strait, further west somewhere off Cracroft Point! Their back-and-forth lasted for about forty-five minutes, and produced some of the most amazing sounds we’ve heard. There was an hour-long pause then two humpbacks began to vocalize once again in Johnstone Strait at 10pm. One humpback was particularly close to our hydrophone in Robson Bight, and began to completely steal the show. He was so loud, in fact, that the sound began to “clip” and we had to turn the volume down to protect our feeble human ears! The humpback closer to Cracroft Point was not deterred by the other’s ostentatious effort, and he had the last word with a few short sounds at 11:25pm. What a beautiful end to the day, we are certainly loving these humpbacks right now.

Summary for October 22 2019 A34s, A42s, Humpbacks (Claw BCX0749) The whales were kind again, and we had another quiet and restful night. Our first calls started at 7:52am with the A34s that we were able to localise in the Robson Bight Ecological Reserve. Heading slowly but surely to the west, we were waiting for them to reach our Cracroft Point hydrophone and maybe enter Blackney Pass. Indeed, we began to hear orca calls on the Cracroft Point hydrophone, starting at 8:50am. Whilst they foraged in the rip alongside a beautiful trap-feeding humpback, we became aware of calls other than A34s. Between trying to spot orcas on our cameras and outside the lab, and getting distracted by the lovely neighbours such as river otters or humpback whales, Suzie heard distinctive A5 (A42s) calls mixed up with A34s. After managing to find a group of whales heading to Blackney Pass, first on our Cracroft Point camera, then on the Parson Island one, we were ready for them to come into Blackney, bathed in this beautiful and shining morning light. By 10:24am, we saw our first orca entering Blackney Pass from the south, All the whales glided past us headed north. A34 and A55 (mother and son) travelled together along with two smaller fins. They were further over in Blackney Pass. At 10:36am, the two big males - A66 of the A42s and we believe A80 of the A34s - came in together, and remained together, fairly close to the lab whilst they passed. At 10:38am, the third and last group was visible around the south edge of Parson Island. In that group there was another sprouting male, and although identification was difficult due to their distance, this could have been A83 with the rest of the A62s at the rear. With the orcas heading north, we manage to take footage of some milling humpback whales in Blackney Pass, and identified Claw at 11:20am. By 11:16am all the orcas cleared Blackney Pass and a few minutes later, we could hear them again on our hydrophone in Blackfish Sound. We heard them until just after midday in the Sound, and around the same time received a report from Jared Towers that the T137s were heading east in the Johnstone Strait. At 2pm, we received a report from Brenda that there was a large group of orcas off Donegal Head with at least two males - it is very likely that this is at least some of the same families we had seen in Blackney Pass earlier in the day, The afternoon was quiet, when at 6:07pm until 6:30pm we heard brief A1 calls once more in Blackfish Sound. Shortly after, at 7:17pm, Blackfish Sound was abuzz with a different sound: a songful humpback whale whose melody we enjoyed alongside our tasty dinner (welcome back to Hanson, chef Megan!). The darkness landed and the humpback continued, bringing in the night with a most discordant yet beautiful array of sounds. He stopped shortly before 11pm, and we all headed to bed wondering what the night would bring.
