I got you a little help from what I believe and vetted to be a snake expert - a thousand nooses around my head if I'm wrong.


This is a central ratsnake. A non-venomous (which would corroborate Tellafriends note that there is apparently no rattle on the tail) rodent assassin.

(This also goes along with an article i read that briefly mentiones rat snakes as a possibility for the diamond pattern https://animals.mom.me/snakes-brown-...onds-7422.html )

Central Ratsnakes Pantherophis spiloides are large (record 256.5 cm) common harmless ratsnakes with a multitude of regional color patterns native to eastern and central North America between the Appalachian Mountains and the Mississippi River Embayment. Pantherophis ratsnakes are keeled-scaled generalists that eat a variety of prey. They do well in urban environments, and are particularly fond of rodents and birds in these habitats.

Central Ratsnakes P. spiloides are currently recognized as distinct from Eastern Ratsnakes P. alleghaniensis, as well as Western Ratsnakes P. obsoletus. Parts of all three species were once generically labeled "black ratsnakes".
