I had two frogs in my pond most of the summer. Today I decided it was cold enough that the water hyacinths were never going to keep growing and I did not want them to rot in the pond. So I was out there with a net scooping them up and dumping them next to the pond to rot over the winter. Scooped out a frog! Poor thing. Couldn't even move really as I am sure it was getting really to sleep for the winter. So I put him back in the pond.
