Humpback Tail Flicking
I have never seen humpbacks do this before. The whale would come up tail first and flick water on the surface. The guide book suggested it help drive food into denser groups. We didn't see it come up like bubble net feeding.
We were anchored, it was late and far from the whale so these images are what I got.
Chin Visible
The whale with the chin visible is T041A3 (identified by eye patch and the pod traveling together). T041A3 was born in 2018 making this a 5 year old orca.
