12:33 PDT Superb sounds!!
We're listening to Transients. They're in the entrance of Blackney. On Channel A

14:12 PDT No calls but orcas nearby
The transients who were busy a short while ago in the entrance of Blackney Pass have moved to the east of CP. From the glimpse we had as they passed CP we think they may have been the T18s.

14:46 PDT No calls but orcas nearby
The T18s slowly made their way to the Sophia's and after some milling around were last seen heading east along the shore.
