Earlier than the arrival of European settlers, Brown Bears had been additionally discovered within the Nice Plains.

Brown Bears are usually sluggish, but when wanted, they will run at speeds as much as 35 miles per hour! They additionally swim as they prey upon fish or cross rivers. Not like the black bear, grownup Brown Bears typically aren’t adept at climbing bushes as a result of their dimension and weight.
