"What's up dude?" Who doesn't love woodchucks? I know we do. Also called groundhogs and whistle-pigs. They're marmots, which are a type of large ground-squirrel. Yes, groundhogs are squirrels, and they have a natural right to be here too. Never trap, shoot, poison, or relocate them, and if you find one you think is injured or orphaned, always call a wildlife rehabilitator before touching!
