Overview
The northern pine snake is one of the largest colubrids in the eastern United States, best known from the sandy Pine Barrens of New Jersey and scattered populations in the Appalachian region. It is a strong burrower, often digging its own tunnels rather than relying solely on rodent burrows.
When threatened, it produces a loud hiss using a specialized structure in its windpipe, often accompanied by an intimidating body-inflating display, despite being completely harmless.
How to identify it
- White to cream ground color with bold black or dark brown blotches
- Blotches often more distinct toward the tail, dimmer near the head
- Small head relative to a robust body; pointed snout used for digging
- Keeled scales
- Round pupils
Habitat & range
Found in sandy pine forests, scrub oak barrens, and dry sandy ridges, notably the New Jersey Pine Barrens and parts of the southern Appalachians.
Behavior, diet & reproduction
Diurnal, an active burrower that digs its own retreats in sandy soil. Preys on rodents, birds, and eggs by constriction. Known for loud hissing defensive displays. Lays eggs in self-dug burrows during summer.
