Hypsiglena chlorophaea loreala
Montezuma Co., Colorado. May 27th, 2011.
Even in May, nights in the Four Corners area get chilly, and the window for road cruising is small. This snake turned up on the last pass of the evening. The flattened head is a bit of viper mimicry, and is somewhat typical of dipsadinine snakes, although I haven’t seen it as much with Hypsiglena.
