The period of the lunar phases (the synodic month), e.g. the full moon to full moon period, is longer at ~29.5 days.
While there are several species of marmots in North America, our woodchuck is found mostly in the eastern United States and across much of southern Canada. In New England, woodchucks inhabit both urban and suburban yards, fields, meadows, woodland clearings, and we see them frequently in grassy areas along highways.
