"Groundhogs are also known as woodchucks or whistle-pigs. They are rodents and are the largest animal in the squirrel family., The time spent observing groundhogs by field biologists represents only a small fraction of time devoted to the field research. W.J. Schoonmaker reports that groundhogs may hide when they see, smell or hear the observer. Ken Armitage, marmot researcher, states that the social biology of the groundhog is well understudied. Despite their heavy-bodied appearance, groundhogs are accomplished swimmers and occasionally climb trees when escaping predators or when they want to survey their surroundings."
