Can you ID this snake? Photo taken Nov 12 in Iowa, USA. We had our first snow Saturday, but it was back up to 60°F today.
Thank you!
Snake ID - IA, USA:
Hello, yes, this looks to me like a juvenile Bullsnake (Pituophis catenifer sayi), family Colubridae.

Boulder County, CO — April 2026
Inspired by an unfortunate IRL incident I witnessed, I wanted a bumper sticker for when you're someone who brakes for snakes, but wasn't seeing anything already available that quite captured the silly vibe I wanted. So I made one. :)
you like Falafel (she likes to climb on my head)
Day 119#: Mexican Bullsnake
Today's animal of the day is the Mexican Bullsnake (Pituophis deppei)!

Also known as the Mexican pine snake, this species of non-venomous snake is endemic to the forests, grasslands, and shrublands of North Central and Western Mexico. They typically reach between 5 to 7 ft in length and are a yellowish-tan color with brown or black squarish spots running down their spines and smaller blotches down along their sides. Their diet consists mainly of rodents and other small mammals, such as squirrels, mice, rats, chipmunks, and rabbits. However, they've also been known to occasionally prey on birds, lizards, and even smaller snakes when the opportunity presents itself.

The Mexican bullsnake can be differentiated from other bullsnakes by its prefrontal scales, which are the large scales found on the topside of the snake's head near the tip of its snout. While most bullsnakes have four of these scales, the Mexican bullsnake only has two. There are two regional subspecies of this species, the southern Mexican bullsnake (Pituophis deppei deppei and the northern Mexican bullsnake (Pituophis deppei jani). I couldn't find much info about the differences between the two subspecies, other than where they are found, but I made sure to include photos of both of them in this post. The snake in the first picture is the southern subspecies while the second one is the northern.
16 May 2025 - Friday Field Notes
Pronghorn prairie sunset.
Got to hang out near a different creek this week. Look at all those Cliff Swallow nests under the bridge! Made entirely out of mud and bird spit.
Chokecherry is going off, and so is the Leafy Spurge.
Bet you weren't expecting mollusks (Asian Clams). Baby Bunny and surprise Milkweed. (I say surprise because we didn't plant it and I know for a fact that patch was not there last year.)
Bullsnake chilling in the garden. Saw two Bullsnakes and two Prairie Rattlesnakes this week. Also got jumpscared by a number of snake shaped twigs.
Flowers are starting to go off! Blue Flax and Sidebells Penstemon.
Two-grooved Milkvetch and Textile Onion. Glad to see the transplanted onions are thriving in their new homes.
Two bullsnake X
saw a thing that was wrong abt snakes and im mad abt it so ima say what the correct thing is to tumblr
basically in this video there was a guy who was saying that bull snakes can hiss cus of a modified epiglottis which was wrong because almost every snake can hiss with just a glottis and the only thing the (not modified) epiglottis does is make the hissing louder
he also generally was stressing the snake out unnecessarily (moving really quickly and like sliding into view until he was like a inch away from the snake)
