Re: Do rock chucks hibernate?

Yes. Woodchucks (rock chucks also) hibernate during the winter. They eat heavily throughout early fall to accumulate body fat and prepare to shelter in their burrows all winter. During the winter, the woodchucks' heartbeat, metabolic processes, and temperature fall off drastically.

During February and March, males are the first to leave burrows. At this time, males fight aggressively. Fat stored before hibernation sustains the woodchuck until green vegetables appear.

Enjoy!
