Lunar Sidereal and Synodic Periods. The Moon's sidereal orbital period (the sidereal month) is ~27.3 days; this is the time interval that the Moon takes to orbit 360Â° around the Earth relative to the fixed stars. 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.
The male of the harem drives out the male offspring upon their awakening from hibernation. Female offspring are allowed to remain in the harem. Sexual maturity is achieved at two years of age, although they do not breed until three years. The lifespan of the yellow-bellied marmot is approximately 13-15 years.
