Wild predators of adult groundhogs in most of eastern North America include coyotes, badgers, bobcats and foxes (largely only red fox). Many of these predators are successful stealth stalkers so can catch groundhogs by surprise before the large rodents can escape to their burrows; badgers likely hunt them by digging them out from their burrows. Coyotes in particular are sizable enough to overpower any groundhog, with the latter being the third most significant prey species per a statewide study in Pennsylvania.
