Holy Cow! Never,ever heard of this before.
the beaver continued to stalk them, lurking just offshore like a shark, following our group up and down the beach, until he finally gave up and paddled away
Never realized how BIG those critters can get, when he first swam up and bumped a kid we thought he was a Labrador retriever
Just guessing, but as hard as they work to build their dams and lay up food for the winter, I imagine beavers are pretty territorial.
Mother nature can be a mean mama!
