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.
Their territory is greatly reduced in Mexico. In the continental United States they live in less than 20% of their original range. Black bears prefer to live in dense forests where there is a variety of food to eat and they can raise their cubs. But they have adapted to many different habitats. They build their dens in caves, burrows, tree trunks, and brush or grass nests. They collect grass and leaves to pad their dens.
