Coyotes

Coyotes are among the wild predators of adult groundhogs in most of eastern North America. To catch groundhogs by surprise before the big rodents can flee to their burrows, was an effective stealth stalker. Groundhogs are the third-most important prey species in Pennsylvania, according to a statewide survey, and coyotes, in particular, are large enough to overwhelm any of them.

The coyote is one of nature's most useful killers thanks to its keen vision and sophisticated sense of smell. The coyote, which is about the size of a small dog, can travel at over 40 mph. Any animal that burrows and spends a lot of time on the ground will be at risk from coyotes.

Unless the animal is a lot larger, that is. This is not to say that coyotes won't pursue larger animals because they absolutely will. Usually, they just work in groups. Additionally, coyotes enjoy stalking their prey and waiting for the ideal opportunity to strike.
