My Dad and I didn't really know what this was till we watched it for a while. Then I saw its tail and am pretty sure it was a beaver - the tail looked wide - not long and thin like a muskrat's. So for now its a beaver. But is hard to be sure since it spent all its time in the water before disappearing under the ice.
Beavers breed only once a year. When the babies turn two-years-old, they leave home in the spring to find mates.
Trapping kills many beavers each year. In the early 1900s, beavers were almost extinct in North America.
Beavers are really cute. They look so furry and I like their meatball noses. I'd like to have one as a pet.
