What is a rockchuck?

A rockchuck, also known as a yellow-bellied marmot (Marmota flaviventris), is a large rodent native to North America, particularly found in mountainous regions. They are known for their whistle-like vocalizations and typically inhabit rocky areas, meadows, and alpine environments. Rockchucks are herbivorous, feeding mainly on grasses, herbs, and flowers, and are recognized for their stocky bodies and thick fur. They emerge from hibernation in the spring and are social animals, often living in colonies.
