Climate zones

Habits and Lifestyle

Eastern kingsnakes are solitary and diurnal reptiles. They spend their day hunting, traveling, basking, or resting under leaf litter. During hot summer days, they may switch to nocturnal activity. These snakes live on the ground but may also climb trees and swim if needed. During the winter they hibernate in caves or rock crevices, abandoned burrows of other mammals, or in hollow logs. Eastern kingsnakes can eat venomous snakes. They have developed a hunting technique in which they avoid being bitten by clamping down on the jaws of the venomous prey; however, even if bitten, they are immune to the venom. Eastern kingsnakes have many predators and they have developed various defensive techniques. When threatened they hiss and vibrate their tail to mimic rattlesnakes. They may also roll into a ball hiding their head in the coils and play dead, produce a foul-smelling musk or strike.

Mating Habits

60 days
at birth
4-20 eggs

Eastern kingsnakes have a polygynandrous (promiscuous) mating system in which both males and females have multiple partners. They breed from March to August and during this time males compete with each other for females. Females may produce more than one clutch in a single breeding season which consists of 4 to 20 eggs. The eggs are usually laid in an abandoned burrow, moist soil or under a log where they are incubated around 60 days. After that the female leaves her clutch and never returns back. Baby kingsnakes are born fully-developed; they are brightly colored and weigh around 9-14 grams. Females usually become reproductively mature at 2-4 years of age while males attain maturity and are ready to mate when they are 1-4 years old.
