Yellow rat snakes (Pantherophis quadrivittatus) are found in the peninsula of Florida and coastal plain of Georgia and the Carolinas. Despite being one of the most common large snakes in the region, many people still struggle to identify the hatchlings and juveniles, which look much different than the adults.
Baby rat snakes hatch with dark gray blotches on a lighter gray background. Yellow rat snakes undergo what is called an "ontonogenetic" color change as they mature. The blotches are replaced by four dark stripes and the color turns from gray to some shade of yellow or orange. Gray rat snakes, which occur in the panhandle of Florida, retain the blotched pattern and gray color throughout life.
Rat snakes are some of the largest snakes in Florida and the USA, with the biggest adults known to top eight feet in length. As their name implies, they feed on rats as well as other rodents like squirrels and mice. They are excellent climbers that also include birds and their eggs in their diet. They often end up in chicken coops, which has led to them being called "chicken snakes" in many areas. Juveniles also feed on frogs and lizards.
