Several people have proposed Caspian Tern as a possibility, but, with all due respect, Caspians don't look much like TRTBs. These were all white, red bills, long red tail streamers. No other bird looks like that. And their calls were correct for that species. I got a good look at close range under ideal conditions. As improbable as it is, there's no doubt in my mind what I saw.
