Wolves alter rivers, and do a whole lot more than we used to believe


Wolves are a very necessary and vital link in a natural ecosystem.

The common belief most of us have is that wild wolves' best and only attribute is killing things. And to a minor extent that is true.  They are, however, good for so much more, including creating bird habitat. It's  shown in this YouTube video shot at Yellowstone Park by Sustainable Man;

they’re built to peck wood       Woodpeckers have thick sculls, outside of which is another shell. In between is a light shock-absorbing sponge-like layer of tiny hollow chambers between the outer shell and the skull. So, NO, they don’t get headaches when they peck.
They do NOT damage trees, although it may look like they do. The trees they peck on are already sick and dieing, attracting the bugs that Woodpeckers are after. Woodpeckers are “cavity nesters”, often living in houses or the holes they peck in unhealthy or dead trees, so they have no need for camouflage.
