These incredible engineering are forever constructing new lodging. In order to do this they take down many large trees, their favorite being poplar and aspen. Thus the expression busy as a beaver!!
To see a beaver I took a few years ago check this out. http://365project.org/radiogirl/extras-challeng/2016-05-15
Thank you so much for your comments and favs, they are so appreciated.
Neat capture of his engineering - there's one very busy beaver (or maybe he has help) in a creek near our dam - the Corps of Engineers is continually trying to break up his dam - just rebuilds!
