Conservation
IUCN Red List status is Least Concern. Populations are generally stable, though individuals face threats from vehicular mortality on roads and habitat fragmentation.
Physical Description
Solid black dorsal coloration, sometimes showing faint traces of a blotched pattern in bright sunlight or between scales. The chin and throat are typically white or light-colored, and the belly features a checkered or mottled dark-and-light pattern. Scales are weakly keeled, and the body is somewhat loaf-shaped with a distinct head.
Size & Dimensions
Estimated specimen length is around 4 to 5 feet. Typical adult size ranges from 3.5 to 6 feet (100 to 180 cm), with exceptionally large individuals exceeding 7 feet.
Habitat
Found in a wide variety of habitats including deciduous forests, rocky hillsides, farmlands, brushy fields, and suburban areas. Highly arboreal and often seen climbing trees or structures.
Diet & Feeding
Consists primarily of rodents, birds, bird eggs, and occasionally small bats. Uses constriction to subdue active prey and is an agile climber capable of locating prey in trees and birdhouses.
Reproduction
Oviparous species. Females lay clutches typically ranging from 12 to 20 eggs in mid-summer, often depositing them in rotting logs, mulch piles, or underground burrows.
Conservation Status
IUCN Red List status is Least Concern. Populations are generally stable, though individuals face threats from vehicular mortality on roads and habitat fragmentation.
Cultural Significance
Highly beneficial to agriculture and human settlements due to their proficiency in controlling rodent populations, earning them appreciation among farmers.
Notable Features
Remarkable climbing ability allowing them to scale vertical tree bark and brick walls easily. When disturbed, they may kink their bodies into an accordion-like pattern to camouflage against shadows or freeze to avoid detection.
