Northern cat-eyed snake (Leptodeira septentrionalis) from the Firestone Center for Restoration Ecology in Costa Rica
This is generally a ground snake, but it gets into the low vegetation at times. And while it is venomous, it is a rear-fanged snake and not a danger to humans. Plus they are quite docile and don't tend to bite anyway. It's a beautiful snake to have around.
