Busy Beavers 1

It's sort of a cliche, but, at times a beaver really can be...."busy as beaver!"  In the wild, beavers are "crepuscular" meaning they are mainly active at dawn and dusk--but here at the Museum, our beavers (two males) are often active during the day, too.  The rest of the time visitors might only see them curled up asleep.  But, when they are awake.....they carry logs....
....using their incredibly powerful jaws to grasp logs in their months--see how far they can open their mouths!
Their front teeth (incisors) are like razor sharp chisels--see the orange enamel on the front teeth?  Great for holding onto logs and cutting down trees, and....
eating, of course!  Beavers are herbivores and eat a variety of vegetation, including tree bark--and they like the very thin green cambium layer just underneath the bark:
Then back to work....more lifting:
  dragging....
Scooping up mud and wet leaf debris...
...and carrying it up on land to shore up the logs--notice they waddle on their back legs to do this!
Then more lifting....
 ....placing the logs where they think best....
....and finally time for another snack:
Whew!  Was that busy enough for you?  More off the beaten path in two weeks!
Cheers,
Lisa
