Diamondback Terrapin #95 Laying Eggs off Sippican Harbor

Sadly for researchers, terrapins are fairly cleaver and stealthy themselves. So, you learn to read tracks. Like a tank, turtles leave “tread marks and plastron drags” as they crawl up from the water and meander along the beach. With the right sand conditions, you get beautiful tracks like those above. The direction of travel can be discerned from the upside down commas that turtles leave as they push off with their rear legs.

And if conditions are just perfect, like this morning, the nest itself shows as an unmistakable pattern in the sand. Within a few hours, wind and sun will erase all signs, and the nest will disappear.
