While on my first inspection tour of the workday, I spied a silhouette which is familiar to me... sure enough, it was a sizable snapping turtle (Chelydra serpentina):
Snapping turtles tend to stay in the water until the female turtles come to land to lay their eggs. Sure enough, a glance of the turtle's hindquarters revealed that the turtle was depositing her eggs into a hole she had scraped into the ground, note the long 'dinosaurian' tail:
I was able to watch her deposit a couple of white, spherical eggs into the hole, but there was no opportunity to catch this on the camera, and I wasn't about to disturb the turtle in this most crucial of endeavors. I did take a photo of her beatific visage, though:
Isn't she beautiful? As with the killdeer nest I marked the location of the nest with a stake so I can inform the day shift of the location of the nest so nobody steps on it or runs a lawnmower over it. The place is starting to look like a maternity ward.
