27 July Orcalab reports:

20:50 PDT Distant calls audible. We're now hearing distant calls from the A12s on the Critical Point hydrophone... sounds like they have entered the Strait via Weynton Pass. Meanwhile, the A36s are taking their time coming down Blackfish Sound, and we have just heard the sounds of rubbing at the beaches!

21:37 PDT Orcas hunting fish. We've been listening to echolocation close to the Critical Point hydrophone. It's probably coming from the orcas that we heard briefly at the rubbing beaches about half an hour ago. Probably, they are one (or more) of the groups that have been in eastern Johnstone Strait over the past few days, though we're not sure. Meanwhile, the A36s are still in Blackfish Sound, & the A12s are eastbound in Johnstone Strait.

22:10 PDT Multiple pod calls audible. We're now listening to A4, A5, & A12 calls on the CrPt hydrophone, so it seems that at least some of the A4s & A5s have returned from the east & met up with the A12s! The A36s are still in Blackfish Sound.

22:37 PDT Multiple pod calls audible. The A4s & A5s, followed by the A12s, are heading north through Blackney Pass on the slack tide.
