Look, don't take. Many states regulate collecting reptiles and amphibians. Photograph it, log it on iNaturalist and leave it where you found it.

Description

The central ratsnake (Pantherophis alleghaniensis), also commonly known as the black ratsnake, chicken snake, gray ratsnake, midland ratsnake, and pilot black snake, is a species of nonvenomous snake in the subfamily Colubrinae of the family Colubridae. A medium to large serpent, the gray ratsnake typically reaches an adult size of 99–183 cm (3.25–6.00 ft) total length (including tail); however, the record is 213.9 cm (7.02 ft).Wikipedia ↗

Habitat

Native to North America, Pantherophis alleghaniensis is commonly found in the forests of the eastern and central United States, west of the Appalachian Mountains and east of the Mississippi River. It occurs relatively continuously throughout the major part of the eastern half of the United States, along the Piedmont throughout Kentucky, from southwestern New England to the Gulf of Mexico, westward to the Mississippi River, and northward from northern Louisiana to southwestern Wisconsin.Wikipedia ↗

When it's active

The central ratsnake hunts using a combination of sit and wait, active pursuit, and nest predation strategies. Its active hunting style leads to a consistent high metabolic state and high average body temperature.Wikipedia ↗

Often mistaken for

Eastern Copperhead, Broad-banded CopperheadThough superficially resembling the venomous copperhead (Agkistrodon contortrix) and often killed as a result of this mistaken identity, the corn snake lacks functional venom and is harmless to humans. Wikipedia ↗Corn snakes can sometimes be confused with venomous southern copperheads (Agkistrodon contortrix), but the two can be differentiated by the narrower head, lighter coloration, and square-shaped spots that are found in red corn snakes.
