Conservation

IUCN Red List status is Least Concern. Populations are generally stable, though local declines occur due to habitat fragmentation and intentional persecution.

Physical Description

Features a distinct hourglass-shaped or dumbbell-shaped crossband pattern of chestnut-brown or reddish-brown over a lighter tan, pinkish, or pale brown background. The head is typically broad, triangular, and uniformly copper-colored.

Size & Dimensions

Adults typically range from 50 to 90 cm (20 to 35 inches) in total length, with maximum recorded lengths exceeding 100 cm. This particular specimen appears to be a juvenile or subadult.

Diet & Feeding

Diet consists primarily of small rodents, lizards, frogs, birds, and large insects like cicadas. They are ambush predators that rely on camouflage to wait for passing prey.

Reproduction

Viviparous (live-bearing), producing litters typically ranging from 1 to 21 young (averaging 4 to 7). Mating generally occurs in late summer or early autumn, with births taking place in late summer of the following year.

Conservation Status

Cultural Significance

Plays an important role in forest ecosystems by helping to regulate small mammal and rodent populations. Often figures into regional folklore in North America.
