Distant calls audible.
This will be a Canada Day to remember! The Northern Residents arrived in the early hours of the morning, and they have kept us busy all day. Megan spotted the first fins in Blackney Pass at 7.32am, heading south. Everyone was already up and about so it didn’t take long for us all to gather on the deck and begin our duties. We had had no calls, the orcas were very far over the other side of the pass, and it was fairly misty and overcast in the morning light - but Helena noticed Pacific White Sided dolphins in and among the orcas, meaning they surely were residents! We saw one large male among some smaller fins, and a separate group of three smaller fins travelling together, and we had some theories but no concrete thoughts on the ID of these orcas. Just as they began to clear our view to the south we heard the first calls, A4s and A5s! Then Dylan (seasoned OL volunteer and currently part of our hydrophone installation team) heard more blows back to the north, and they sounded very close. Sure enough, round Burnt Point we saw several more dorsal fins streaking through the water - close in to the lab! We were able to see their fins and saddle patches much more clearly, and we quickly identified them as the A35s from the A4 clan. A4s! Hooray! They sped past the lab quickly, and as they cleared our view - we saw the earlier group pass close by our Cracroft Point camera at 8am. That large male we had seen looked like A66, and sure enough more A5 calls as they hurried east in Johnstone Strait. Only a minute later, we started to hear A4 calls and then… a “weeawuu”! Springer’s call! Had she and her two offspring been the group of three we had seen initially in Blackney Pass? All of the groups made their way east in Johnstone Strait, the A35s continuing down the Cracroft shore, while the A42s crossed over the Strait and towards the Robson Bight Ecological Reserve. At 09:10am, we saw a few fins heading east, close to our Critical Point camera - pointed directly for the rubbing beaches… At 9:19am our focus shifted momentarily from the orcas, as we saw Stitch the humpback breaching in front of us in Blackney Pass. We eagerly awaited the orcas at the Rubbing Beach camera, and at 9.32am our patience was rewarded. The A42s came in and rubbed as they travelled east. Dylan suspected A56 from the A4s was travelling with the A42s and this was later confirmed by Jared Towers who caught up with them east of Naka creek. We, meanwhile, were pretty excited to have seen the first rub of the season! We don’t yet have our underwater cameras installed sadly, but we did get some lovely surface footage. The A42s continued east, and around this time Jared Towers reported the A35s had begun to cross over the Strait and were pointing towards the beaches, too. Better yet - he confirmed Springer (A73) and her two offspring were in the mix! We were ecstatic. These two groups crossed over and rubbed at Strider beach for a little while, and then finally came back east and into view of our Main Rubbing Beach camera, and both the A35s and A73s came in for a rub at 10:42am. They rubbed, headed east, and then turned again west. This was just the morning! The afternoon came in with a flurry of reports in all different directions . At least some of the A35s crossed once again over to the Cracroft Island side and headed west. Meanwhile, the A73s foraged in Robson Bight for a little while, then made their way west along the Vancouver Island shore and were seen by the hydrophone team at Kazumi beach at 12:48pm. We were hearing sustained A4 calls at this point. The A35s on the Cracroft side headed west past the “Cliff” around 12:09pm, and by 13:13pm they were at the Baron Reefs, approaching Cracroft Point. Once they reached CP, they then turned again and headed back to the east at 1:56pm. The A73s did the same - turned and headed back to the east, After their morning rub, the A42s along with A56 continued east past Naka Creek. They too turned back to the west passing eventually under the “Cliff” on Cracroft Island at 12:55pm. From there they crossed back over the Strait. We suddenly heard close echo location off the eastern headland of Robson Bight. We saw one male and some smaller fins forage in the Bight. This group was also headed west. This may have been either the A42s or part of the A4s. It was not entirely clear as there was a lot of movement on the part of the whales throughout the day. By 2.01pm the A42s were up to Kaikash Creek, and at 3.04pm we received a report from Dylan and the hydrophone team that two of the A42s were rubbing at Kazumi Beach - literally right in front of them! The last confirmed visual ID was of some members of the A42s - including A66 - heading east again at Kazumi Beach at 4:14pm. We heard sustained rather distant A4 and A5 calls in Johnstone Strait for the remainder of the afternoon, but had no more visual confirmations of the whereabouts of the A35s or A73s for the rest of the day. These groups often spread out and intermingle - so it can make tracking the matrilines a little tricky! The fading calls on our Critical Point hydrophone made us wonder if some of the A4s were heading further west in the Strait. At 6.51pm we saw at least one male and three smaller fins heading east around Cracroft Point. We wondered again about the A42s. At 7.03pm we actually saw some orcas in Blackney Pass! Another group with a single male and a few smaller fins. They were nearly clear to the south by the time we saw them. No helpful calls. It could be that this group was some of the A4s, who may have snuck round Hanson Island through Weynton Passage and into Blackney Passage. It was very windy today making visuals rather challenging. We last saw these orcas on Cracroft Point camera at 7:27pm, and it looked like they had joined up with the earlier group that we had seen in Johnstone Strait - all were heading east when we last saw them. Finally at 9:14pm the A4s started calling again. The night is unfolding as we write.
