While many aspects of the reproductive ecology of Eastern Box Turtles are well known, numerous gaps remain regarding inter-populational variation in clutch size, egg viability and clutch frequency, all vital components of population models. We collected data on nesting ecology of a dense Long Island population of Eastern Box Turtles for three years. Average clutch size was only 4.1 eggs/clutch, which is surprisingly low compared to a nearby population. Conversely, egg viability at this site was site was surprisingly high (95%). It also appears that Eastern Box Turtles lay only one clutch/year, in the later half of June, in southeastern New York.
