Rough Green Snake

Rough Green Snakes are present at Chert Hollow Farm but not commonly sighted; they are primarily an Ozark snake and thus we’re toward the northern limit of their range. From 2006 to 2012 we had only 3 observations: one near the vegetable field gate, one seen through binoculars in the talons of a Broad-Winged Hawk, and the one photographed below, which I found on the patio of the house in early October of 2012:

We don’t know whether the infrequent sightings reflects a low population or good camouflage with green vegetation. I almost overlooked even this individual, which stood out like a sore thumb against the concrete backdrop, because my initial impression was that it was a green onion top (& I took a closer look trying to figure out why in the world there was a green onion top on the patio).
