Here's a bright-eyed little guy. This green snake was slip-sliding through a cedar tree. If you check out Rurality's blog, you can see the interesting color change these snakes go through after death.
Green snakes are very arboreal. I have rarely seen one on the ground, but I have seen them on branches like this one, peeking out of knot holes, and more than once falling from the top of a tree...seemingly no worse for the fall.
Once, I looked up directly overhead to see what the blue jays were screeching about and PLOP...a green snake falls practically on to my upturned face.
They certainly are pretty, and I could swear I read once that they were very mildly venomous, but I am too busy to go verify that this morning and should not even be taking the time to write this little post.
Tempis fugit...or something like that.
