During winter, the turtle hibernates, usually in the mud at the bottom of water bodies. The turtles mate in spring and autumn. Females dig nests on land and lay eggs between late spring and mid-summer.

These turtles can get oxygen by pushing their head out of the mud and allowing gas exchange to take place through the membranes of their mouth and throat. This is known as extrapulmonary respiration.

Many turtles overwinter outside of the water, during which time they often create their nests for the year.
Hibernacula must be well oxygenated because, unlike some other turtle species such as painted turtles, map turtles need to absorb oxygen from the water to survive the winter. [6] They typically bask in groups and are diurnal, meaning they are active exclusively in daylight hours. Northern map turtles are also quite shy and difficult to approach ...
The species tends to decrease in movement and feeding over the cooler winter months. [4] C. expansa is described to also show head bobbing and self-grooming actions.
