We found this happy beaver on the same morning that I took the shot below (both at Mizzy Lake in July 2009). We actually heard him chewing a long time before we got close enough to take a good look. There was a partially submerged tree that he was using as a breakfast chair and I think he probably felt quite safe surrounded by water.
We sat down on the bank about 15 ft from him and watched him for about half an hour, laughing at his methodical chewing pattern; just like typewriters of pre-70s vintage: crunch, crunch, crunch…left to right, then a quick return to start the next line. As you can see from the skinned branch on the right, the method is effective!
Amazing creatures. Their role in shaping the development of Canada is astounding.
