Note About something missing

I forgot to mention that the last couple of time I was at Penns I would hear the toads (we called them hop toads growing up and you would get warts if you touched them) not a good amount of them but a few as of last Wed. they are finished with their annual mating ritual of signing and the males hanging on the females backs no matter what. Years ago we would see them ever where and the sound would be all night but that has not been the cast the last few years, something is wrong and we need to fix it fast before the toads become gone from our world as are most of the frogs. I saw the strings of eggs that have been laid and there are not that many, have you noticed the same or have you not even taken note of their absence?
