No orcas present.

Summary of August 24th: We had a busy night here at OrcaLab last night, followed by a relatively quiet day in Blackney Pass. From 11:00 pm to 11:30 pm last night we heard calls and rubbing sounds on our Rubbing Beach hydrophone. As the orca traveled west, we were able to hear their chit-chat on our Robson Bight hydrophone until around 12:22 am. The calls became a bit masked by boat noise, but continued faintly. At 12:30 am, calls registered on both our Cracroft Point and Parson Island hydrophones, and the orca seemed to be headed into the Pass! As we listened for their blows outside the lab, there appeared to be two groups headed north fast through Blackney. The orca entered the pass at around 12:40 am and cleared quickly - exiting by 01:07 am! They vocalized the whole way, continuing their calls until they made it to our Flower Island hydrophone. Calls persisted until 02:00 am on the dot and the rest of the night was still. At 10:53 am, there was a group of Bigg’s that snuck up on us in Blackney pass. We are fairly certain that this group of three small fins and one male was the T060’s! They traveled north determinedly, and cleared the pass by 11:07 am. To spice things up, we began hearing I15, A30 and A5 calls on our Flower Island hydrophone at 11:33 pm. We had a report from Megan at 12:05 pm that there were orca spread from Hanson Island to Swanson Island at Double Bay heading east, with another group between Lizard Point and Donegal Head. It appeared that the A50s an I4s were in the lead, followed by the A54s and A25s with the A42s trailing. The Bigg’s were seen heading West at Stubb Island. We continued hearing resident calls off of Flower Island until 1:30 pm, and at 1:35 pm, we had another report from Megan that the orca had formed a resting line in Blackfish Sound and were heading towards Queen Charlotte Strait. At 4:15 pm, at least three Humpbacks began breaching, pec slapping and tail slapping in front of the lab - it was a beautiful sight! The rest of our afternoon and evening has been quiet so far. However, we just received a report from Kate that orca passed by Bere Point at 7:00 pm and, after a bit of back and fourth, are heading west towards Blackney Pass! We hope for another eventful night here at OrcaLab!
