north country tern - pics/video

[cga...@sau53.org]

While working around the 3 season camp on Millsfield Pond (near Errol) a bird flying across the pond caught my eye.  It never got closer than about a quarter mile away from me.  I think I have enough photo evidence to conclude it's a tern and my best guess is that it's a common tern.  For those of us that like to help to solve a mystery, please let me know what you think based on the photos and video.  Wish I had better photos but like I said, it didn't come close enough.  

Happy Birding.
