Possible Sandwich Tern or hybrid at Robb Field 8/19

Just before 4 PM I was looking through the tern flock on the mud flats at the east end of the bike path by the skate park. There was one tern with a dark bill with a yellow tip. It flew with a few others and I lost track of it and I have not been able to relocate it so far.
