Like the better known groundhog (also known as a woodchuck), the rock chuck is a member of the marmot family – it is a large rodent, related to the squirrel. Rock chucks are common to the western United States and Canada. Both rock chucks and groundhogs are found throughout Wyoming and Colorado. While rock chucks, like groundhogs, will inhabit grassy and forested areas, they will also populate desert and mountainous areas that groundhogs avoid.

Rock Chuck Appearance and Habits

Rock chucks are typically smaller than woodchucks. They average about 8 pounds and can grow up to two feet long. Rock chucks are lighter in color than woodchucks. Their fur has a tawny yellowish-brown color; their bellies are typically yellowish-orange, giving rise to their nickname “yellow-bellied marmot.” A rock chuck’s neck is dotted with yellow spots. They have a splash of white fur between their eyes as well.

The rock chuck and the groundhogs, though similar, have totally different living habits. While groundhogs are solitary and territorial, rock chucks live in colonies. Unlike groundhogs they may take multiple mates simultaneously; the harem, along with their littlers of 3-5 offspring per female, all live together in their colony-burrow, where they will spend approximately 80% of their life. Rock chucks typically hibernate from September to May. When they are not hibernating, they are foraging for food.  Rock Chucks are herbivores and particularly enjoy flowers and tomatoes! Unlike groundhogs they are also capable of scrambling up trees to get away or to get at a tasty fruit.

Rock chucks will whistle loudly when they are in danger. This whistling is a means to warn other nearby marmots of trouble and gives rise to one of their other common nicknames: “Whistlepigs.”

Rock Chuck Removal

Rock chucks can get into any number of places. Like groundhogs, they will burrow under foundations and concrete pads. They also can get into crawl spaces and HVAC systems. Once they start lurking around they will frequently damage posts by gnawing on them and destroy gardens. Sometimes they will urinate and defecate near their burrows, which might mean on your deck or patio.

Creature Control is able to trap and remove rock chucks – although, due to the numbers of rock chucks that can inhabit a single burrow, this can take some time an dedication.
