We used to have beavers living in the swamp behind our house. The river moved and left a low pondy area in the middle of which the beavers had built a lodge. At first I did not believe they were actually beavers, which I considered to be northerners, and assumed the felled trees were the work of nutria. However once I saw a couple swimming in the river, there was no doubt. For us they were just amusing as it was unlikely that they could dam up the river. I do not know where they live now as the recent drought years have dried up their old home. I also miss the sound of all the frogs that lived there too.
