These are in fact Hyla versicolor. It may have been a warm night which explains why their trill rate is slightly faster than normal. Check out my other video called gray tree frog aggressive calling. This video has Hyla chrysoscelis and I think if you compare the two, you should be able to hear the difference fairly easily.
Yeah, that call is the aggressive call, which you hear only occasionally compared to the other call, which is the advertisement call. That's part of the reason I have to do this complicated experiment to make them give aggressive calls in the lab-they don't do it often enough to just observe in the field.
That is an ingenious low-tech way to make frogs interact! I used to have two male grays, H. v. and H. c. I only found out when they both started calling. Both have since died of old age, but I now have a tiny (1in) rescue. Don't know the sex yet.
are these versicolor or chrysoscelis?, sounds almost to fast to be versicolor

the call at 1:00 is the call i hear about 3 times a night, compared to the very common one in the background
