Thanks for the idea of dual monitoring.

We will begin to monitor both water and air temp....hmmm, slunds like and
indoor/outdoor thermometer might do the trick!

Any thoughts baout why they start and stop at different times in the
evening/night?

I think they croak when water and air temperatures reach a certain range.
Why breed if your eggs are going to freeze?
Bullfrogs usually breed when air temperatures are about 77F and water
temperatures are between 68F and 89F.
I know mine usually started courting here in SE WA about the end of June.
Our Junes can be chilly at times.
