Conservation

IUCN Red List status is Least Concern, due to its wide distribution, presumed large population, and tolerance for habitat modification.

Physical Description

Displays distinctive hourglass-shaped crossbands that are lighter reddish-brown in the center and darker chestnut-brown at the edges, contrasting against a tan, pinkish, or light brown background. The head is distinctively wider than the neck, triangular, and often a solid coppery-tan color. Scales are keeled.

Size & Dimensions

Specimen in photo appears to be a juvenile or subadult, roughly 30-50 cm. Typical adult length ranges from 60 to 90 cm, with maximum recorded lengths up to 135 cm.

Habitat

Deciduous forests, mixed woodlands, rocky hillsides, wetland edges, and suburban areas near wooded patches, typically at elevations from sea level to 1,500 meters.

Diet & Feeding

Diet consists primarily of small rodents, lizards, amphibians, large insects, and occasionally birds. Utilizes an ambush hunting strategy, waiting motionlessly for prey to pass within striking distance.

Reproduction

Ovoviviparous, giving birth to live young. Females typically produce litters of 1 to 21 neonates (average 4-7) in late summer or early autumn.

Conservation Status

IUCN Red List status is Least Concern, due to its wide distribution, presumed large population, and tolerance for habitat modification.

Cultural Significance

Plays an important ecological role in controlling rodent and pest populations. Often subject to fear and misunderstanding by humans due to its presence in suburban areas.

Notable Features

Features heat-sensing pit organs located between the eye and nostril on each side of the head, allowing it to detect warm-blooded prey in total darkness.
