Orca/humpback double header and Dall's porpoise

A small pod of orcas were observed near Vanderbilt reef.  Unfortunately the pod separated before we could get near them, and I was only able to photograph a juvenile male.  He was difficult to track, as he was moving quickly, zigzagging, and porpoising out of the water.  Suddenly he began slapping his tail and breaching.  A flock of gulls appeared out of nowhere and began circling the area.  I believe he made a kill.  
We eventually made our way into north pass of Shelter Island and saw two humpbacks.  
On two separate occasions throughout the day we saw pods of Dall's porpoise near Vanderbilt reef.
