04 October Orcalab reports:

09:10 PDT No calls but orcas nearby
The A12s, A36s & I46+I80 are heading west in Blackfish Sound, after travelling north through Blackney Pass. They are mostly silent, but made a few calls as they headed through Blackney Pass.

12:32 PDT Distant calls audible.
We began hearing distant "A1" and "G-I" calls on the Critical Point hydrophone about half an hour ago... sounds like at least some of the orcas who headed north through Blackney Pass earlier this morning have re-entered Johnstone Strait via Weynton Pass.

14:05 PDT Orcas (may be) approaching cameras.
The A12s, A36s & I46+I80 are heading east in Johnstone Strait, now opposite Blackney Pass. They are mostly on the Vancouver Island side of the Strait, but may be crossing over towards Cracroft Island. Channel A.
Orcas (may be) approaching cameras.

14:25 PDT A "G-G" group of orcas, including the G18s, has just headed into Johnstone Strait via Blackney Pass & are in front of CP. Channel A.

16:22 PDT Superb sounds!!
After lots of foraging and playful behaviour all the groups for the time being at least have passed CP and are now going east.

17:31 PDT Superb sounds!!
The various groups of orcas are in or near Robson Bight... we're listening to them on the Critical Point hydrophone.

18:36 PDT Orcas rubbing on the shore bottom.
Some of the orcas have reached the rubbing beaches - Channel B.

19:10 PDT No calls but orcas nearby
The orcas have left the rubbing beaches and headed east. The sounds of pebbles moving that we're hearing are from waves crashing on shore at low tide, not from orcas rubbing. Apologies to those who logged on after we sent an alert, only to find the (brief) rub was over.
