Life Cycle

Mating can occur in any month from April and November. Nesting generally occurs between early May and mid-June. Females come out to lay eggs in either the morning or evening. An open site is selected, and the female digs a bowl-shaped nest cavity in loose sand, loam, or plant debris. An average range of 20 - 40 eggs are laid, and incubation lasts from 75 -95 days. The eggs hatch in August to Octobe, and the young emerge from the nest and head for water where they hide under cover from predators.
