Beaver in Cabin John Creek

Swimming beaver, Cabin John Creek

Last week I saw unmistakable evidence of a beaver in Cabin John Creek.  I decided to try and take a picture of the actual beaver.  It took me a couple of days to do it since beavers are nocturnal and go to bed right around sunrise, but as you can see, I managed. 

When this beaver noticed me it swam upstream for a bit then, with a splash went under water and didn't come back up.  I believe it swam to it's lodge and decided it was bed time.

Beaver stripped branch

Beavers eat the bark off tree branches, so there were branches without bark floating in the water. This is one of the telltale signs of active beavers.

Here's a closer shot of a branch that a beaver has eaten the bark off of. You can see the gnaw marks on it.

A beaver stripped some of the bark off this sapling but left it standing.  You can see a few gnaw marks on it.
