Guess what!!
The frog that I just finished testing with last week (frog 6....Lil' Porker), croaked this morning 8 times at about 7:49 am!! I didn't even have the Wood frog vocalizations playing and the conditions were normal living conditions, 65-70 F temps about 60% humidity.....nothing that resembled the mating conditions as Test A is meant to mimic.
It had to be the barometric pressure.....it snowed really hard yesturday and there was 25 mph winds. This morning though it was pretty calm outside, but overcast. It was silent and dark in the house when he croaked too. Hmmmmm.......
