Woodchucks put on a thick layer of fat late in the summer because they do not store food over the winter months. While foraging, woodchucks are always in groups. One member of the group stays on guard watching and listening for predators. During feeding, woodchucks stop every few minutes to keep on the lookout. They are never too far from a burrow opening to dash into when danger arises.
Woodchucks are diurnal so they hunt for their food in the daylight hours.
Their feeding time is in the morning and late afternoon. They will climb trees and even swim to get food. Woodchucks live in open grasslands, pastures, and woodlands. Cover is sparse here and not concealing so it is easier for the woodchucks to see predators coming. These are also ideal places to dig their underground burrows in which they live.
