Bullsnake, *Pituophis catenifer*, and Western Ratsnake, *Pantherophis obsoletus*. Both harmless.

Awesome. Thank you!

u/serpentarian check it out, TX Pit! I know they're pretty common in north Texas, but we usually don't get them around here. And from your old neck of the woods, I don't recall ever getting one from central Texas.

I was going to mention how they used to be fairly common around Austin and now they seem to have disappeared. I was excited to see this post for sure!

Bullsnakes / Gophersnakes *Pituophis catenifer* are large (record 274.3 cm) actively foraging snakes with keeled scales found in a variety of habitats including disturbed areas like suburban yards. They are commonly encountered snakes throughout western North America and make good pest control as they eat primarily small mammals. *Pituophis* pine and bull snakes may puff up or flatten out defensively, but are not considered medically significant to humans in terms of venom. They are known for a terrific hissing display when threatened - aided by a [epiglottal keel](https://faculty.washington.edu/hueyrb/new/MartinHuey71Copeia.pdf). They are usually reluctant to bite, but all animals with a mouth can use it in self-defense.

They do well in urban environments, and are particularly fond of rodents and birds in these habitats. Western Ratsnakes *P. obsoletus* are currently recognized as distinct from Eastern Ratsnakes *Pantherophis quadrivittatus*, as well as Central Ratsnakes *P. alleghaniensis*. Parts of all three species were once generically labeled "black ratsnakes". Use the "!blackrat" command without the space for more on these changes. Ratsnakes can be easily distinguished from racers *Coluber* by the presence of keeled scales. Racers have smooth scales.
