Last year, the peepers were out for maybe a week. I was only able to tape them once. We thought it was the sudden cold that had set them back. There was also the pond drying out while the eggs were unhatched, but primarily we thought it was too cold for them.
Then there's this year. This year, it became warm and the noise was deafening. Peep, peep, peep, all night long. I heard them everywhere there was standing water. You could hear them as you drove or in the background in a parking lot, behind all the ambient noise. But then, I knew what to listen for. They went silent after a while. Again, it had turned cold and I thought that was why. But then we had a little rain and they started again. Give them some damp this year and they go crazy with noise all over again. Especially the last couple of days.
So my conclusion is that rain is much more important to them than temperature. In prior years, when they seemed to peep and peep and peep, we had very wet springs. Overly wet. And last year was overly dry. And this year, we were down a couple of inches and are trying to catch up.
Just some significant detail I will no doubt use some day.
