Conservation
IUCN Red List status is Least Concern. Populations are generally stable, though local declines occur due to habitat fragmentation and road mortality.
Physical Description
Characterized by a pattern of dark blotches (brown, gray, or black) along a lighter background of gray or yellowish-brown. The head is relatively distinct from the neck, eyes have round pupils, and the scales are weakly keeled.
Size & Dimensions
Typical adult size ranges from 107 to 183 cm (42 to 72 inches), with a maximum recorded length exceeding 210 cm (83 inches). The specimen shown appears to be a medium-to-large sub-adult or adult.
Habitat
Found in a wide variety of habitats including deciduous forests, rocky wooded hillsides, agricultural fields, swamp margins, and suburban areas. Frequently climbs trees and swims adeptly.
Diet & Feeding
Primarily feeds on rodents, birds, bird eggs, and bats. Employs constriction to subdue active prey and is an opportunistic forager both on the ground and in elevated perches.
Reproduction
Oviparous species, females typically deposit clutches of 12 to 20 eggs in decaying vegetation, rotting logs, or loose soil during the early summer months.
Look-alikes
Frequently confused with other large rat snakes, fox snakes, and certain species of water snakes or racers, but distinguished by head markings, scale keeling, and belly patterns.
Conservation Status
IUCN Red List status is Least Concern. Populations are generally stable, though local declines occur due to habitat fragmentation and road mortality.
Cultural Significance
Highly beneficial ecologically for controlling rodent populations around agricultural and residential areas, though sometimes mistakenly feared due to its size and defensive behaviors.
Notable Features
Renowned for their exceptional climbing abilities, often scaling vertical tree bark, brick walls, and rafters, as well as an ability to swim well when crossing pools or streams.
