Range
The range of the common map turtle is northeastern United States, as far south as Virginia, West Virginia and Tennessee.
Habitat
Common map turtles prefer rivers and quiet backwaters, sometimes large bodies of water, such as lakes.
Gestation
Approximately 90 days
Litter
Clutch: 9 to 17 eggs
Behavior
The common map turtle may seek concealment in bottom vegetation, or rely on their speed in swimming, which is considerable. In the spring they spend most of the day basking in the sun, but in warmer weather they head for deeper water. At the approach of winter they head for shallow water again. They seem to have a reluctance to burrow into the mud, as they are quite often stranded on shore when the water has frozen over
Reproduction
Mating for the common map turtle is usually in April, although occasionally in the fall. Egg laying season lasts from late May until July, with most individuals depositing eggs in June. Females will wander for long distances inland, searching for suitable nesting places, preferring soft, ploughed soil or clear, dry sand. The nest is excavated to a depth to which the hind foot will conveniently reach. The eggs are ellipsoidal in shape, of a dull white color, and have a soft, easily indented shell. An occasional nest remains intact throughout the winter, as newly hatched young ones are sometimes found in May or June.
