Colubrids vs Boids - Intelligence

There was no pinky after he was done eating, the pinky was sitting on my palm, and he went for my pinky. So while he may of still used sight, he relied more on scent.

It's most likely a bit more complicated than that, but you're headed in the right direction.

For an animal that lacks binocular vision, depth perception works a lot like a camera. If you look at a photo with a very shallow depth of field, you'll have an idea of how the world looks to them, because they can only focus at one distance at a time. Your fingertip probably looked just like a pinky mouse, since the rest of your hand was out of focus. The fact that you smelled like a mouse just confirmed it for the snake. It's not so much that he relied on scent to find prey. It's more like he saw something that looked like prey, and the scent agreed with the eyes.
