Woodchuck

Chunky groundhog of the field edge — whistle pig with a weather-day myth.

Least Concern

Marmota monax

Overview

Woodchucks (groundhogs) are large burrowing marmots of eastern and central North America. Stocky brown bodies and short legs suit a life of digging extensive burrows in fields, roadsides, and woodland edges, whistling alarms and hibernating through winter.

For US collectors, the woodchuck is an everyday countryside mammal — roadside burrow, upright lookout pose, and Groundhog Day fame wrapped around a common marmot.

Habitat

  • Field edge
  • Roadside embankment
  • Meadow
  • Woodland clearing

Open fields, meadows, roadsides, and woodland edges across the eastern and central United States where deep soils allow burrow systems.
