Yes, they move around a lot. I have 2 large ones that come and go 2 or 3 times every summer. Not the brightest critters in the world. When I had the land across the lane fenced with field fence, I would occasionally find one dead that was either coming from or headed to the pond. They'd get their head through the fence and just keep trying to get through until they dehydrated and died. Their feet could dig some pretty good holes after hours of pushing in one spot.
