Wood Turtles Laying Eggs

5-10-13 wood turtle burying eggs IMG_3717Congratulations on correctly identifying the trails as being made by turtles! Even though you did not have the benefit of knowing their width, many of you took a stab at the naming the species of turtle that made them. Hats off to Jason, who correctly identified them as wood turtle trails, especially as it is relatively early in the season for them to be laying eggs.

Two female wood turtles (so-called because of the resemblance of their top shell, or carapace, to wood), were on their way out of a shallow wetland to dig into soft sand about 6” deep and lay their (4 – 18, usually 8 or 9) eggs. The size of the footprints, tail drag and 7-inch flattened shell path help to identify these trails as those of wood turtles. Although you can follow the tracks and see exactly where the trails end, it would be hard to detect that excavation and egg-laying has taken place at these sites, as the holes have been filled in and smoothed over with the turtles’ bottom shells, or plastrons. Predators with a good sense of smell, such as foxes, raccoons and skunks, however, have very little trouble locating turtle nests. Research shows that 85% of wood turtle eggs and hatchlings are lost to predation. The wood turtle population is in decline in the northeast in part due to human development which not only decreases wood turtle habitat and increases the number of people collecting these turtles, but also increases the number of predators. (The wood turtle in the photograph has just laid her eggs and smoothed over the nest site in front of her head by walking backwards over it while pressing her plastron to the ground.)

    Do you try to protect turtle eggs when you know where they are?
