Non-venomous (Aglyphous - lacks specialized venom-delivery fangs)
Danger Level
Harmless. These snakes are not a threat to humans or pets; they may bite defensively if cornered or handled, but the bite is minor.
Family
Order: Squamata, Suborder: Serpentes, Family: Colubridae, Subfamily: Colubrinae, Genus: Pantherophis, Species: P. quadrivittatus
Conservation
Least Concern (IUCN). Highly adaptable to human-modified landscapes, though habitat loss and road mortality remain threats.
Physical Description
Yellow to tan base color with four dark longitudinal stripes running the length of the body. The head is relatively distinct from the neck, with large eyes and round pupils. Scales are weakly keeled.
Size & Dimensions
Specimen appears to be an adult. Typical adult range is 3 to 6 feet (91–183 cm), with some individuals reaching up to 7 feet.
Habitat
Found in various habitats including pine forests, hardwood hammocks, swamps, marshes, and agricultural fields. Frequently found in suburban areas, near barns, and within residential gardens.
Behavior & Temperament
Highly arboreal and excellent climbers. Diurnal or crepuscular, though nocturnal in hot summer months. Generally docile but may vibrate their tail in dry leaves or musk when threatened.
Diet & Feeding
Primarily feeds on rodents, birds, and bird eggs. They are powerful constrictors that hunt through active foraging and climbing.
Reproduction
Oviparous (egg-laying). Females lay clutches of 5 to 30 eggs in decomposing vegetation or hollow logs during early summer, which hatch in late summer.
Venom Profile
Non-venomous - no medically significant venom.
Look-alikes
Confused with the Corn Snake (Pantherophis guttatus) or Garter Snakes (Thamnophis sirtalis). Distinguished from Garter snakes by its larger size, keeled scales, and specific four-stripe pattern.
Conservation Status
Least Concern (IUCN). Highly adaptable to human-modified landscapes, though habitat loss and road mortality remain threats.
Cultural Significance
Extremely beneficial to humans as natural pest control, keeping rodent populations in check. Often affectionately referred to as 'chicken snakes' in the south.
Notable Features
Known for their incredible climbing ability; they are often found in rafters of barns or high in trees. The 'yellow' stripe phase is a classic regional color variant of the Eastern Rat Snake complex.
