: I've noticed thermal orientation in captive colubrids. Remember, heat-sensing organs in boids and crotalids were selected for on the basis of pre-existing sensory neurons, and most vertebrates have heat-sensitive neurons, so it's not really surprising.

I recall that Dr. Tom Swain was working on the heat sensitivty of Pituophis at the UNiversity of Colorado (Boulder). He was there in the late eighties but I lost contact with him. You might ask Hobart Smith (same University) about that.
P.S. If you find out about where to find Dr. Tom Swain now, I'd love to get a note.
