Oxyrhopus petolarius Banded Calico Snake
Also known as:
False Coral Snake, Forest Flame-snake, Calico Snake
There is disagreement among herpetologists about whether the correct name for this species is Oxyrhopus petola or Oxyrhopus petolarius. I'm using O. petolarius in keeping with The Reptile Database.
Subspecies I've seen:
O. p. digitalis

On our last night at Madre Selva, I went out for a long hike with Raul, the caretaker of Madre Selva, and Emerson, an employee of MT Amazon Expeditions who among many other talents is an excellent herp finder. Emerson spotted this young snake on the ground, and quickly captured it so everyone could photograph it the next day. I had wanted to photograph it where it was found, but I was slightly too late for that. At this point the snake had gotten all wriggly and unwilling to sit still in the forest. My poor consolation prize was this photo of it coiled around a stick.

The next morning I could have joined in on a group photo session with the snake posed on the ground, but my heart wasn't in it. I just took a couple of snapshots with my iPhone as a memento of what it looked like from above.
