At other times he reminded me of a sea otter when he appeared to be floating on top eating his food. I don't know enough about him and couldn't really tell if he was floating on his back or standing on the bottom of the pond.
Whoever coined the phrase "Busy as a Beaver" was spot on. He or she very industriously chewed the lily pads off their stems and either ate them right there or swam to shore and took them back to a spot underneath a tree, and then kept coming back and repeating the process dozens of times.On line I read: "Beaver who inhabit smaller streams or ponds will make lodges so they can be active all winter and as defense against predators. The lodge will be made of primarily mud and branches."
Beavers are highly social animals. They live in family groups consisting of the parents, young of the year and two-year old offspring. Litter size averages 3, so a family of 8 beavers would not be uncommon.
Finally our beaver retreated to shore, we watched as it stood on its hind legs and chewed off a few lower branches of the tree and then disappeared out of sight.
