Eastern Indigo Snake

Snapshot

North America’s largest native snake — a glossy bluish-black giant of southern Georgia sandhills that uses gopher tortoise burrows and eats other snakes, including rattlesnakes. Federally threatened and Georgia state-listed threatened. Non-venomous. Leave alone; do not relocate casually; report sightings through proper recovery channels when useful.

Description and identification

SREL: 60–84 inches — the largest native U.S. snake. Glossy bluish-black throughout, including the belly; chin and sides of the head often reddish to orange-brown. Juveniles similar, usually with more red on the head. Males grow longer than females. Smooth, large scales give a polished look unlike the duller sheen of black racers. Round pupils; no heat pits.

Look-alikes

Black racer — much slenderer, usually under 5–6 feet, often with a pale chin but less red. Black / gray rat snakes — weakly keeled scales and a loaf-shaped cross-section. Coachwhip — two-toned adults with a whip-like tail. Size, deep gloss, and reddish chin are indigo clues — still do not approach a large black snake in sandhill country.

Range in Georgia

Florida and southern Georgia; smaller populations in southern Alabama and Mississippi. Historical South Carolina records questionable. Full native range is this limited southeastern footprint — map the whole species range, not a Georgia-only crop.

Habitat preferences

Strongly tied to xeric pine–oak sandhills. Heavy winter use of gopher tortoise burrows for refuge, nesting sites, and shelter from heat. In warmer months individuals may travel long distances and forage along wetland edges while still depending on the sandhill–tortoise system.

Natural history

Strictly diurnal and often active even in cool winter weather. Breeding occurs in winter. When threatened, may flatten the head, hiss, and vibrate the tail, but rarely bites. An apex snake predator of the sandhill system — ecology and recovery are inseparable from healthy tortoise burrow landscapes and connected uplands.

Food preferences

Mammals, birds, frogs, and other snakes — commonly rattlesnakes and cottonmouths — and occasionally young gopher tortoises.

Temperament and encounters

Often calm by reputation, but this is a wild listed animal. No handling without proper federal/state permits. A chance sighting is a privilege — photograph from a long distance if at all, then leave.

Conservation and legal notes

Federally threatened (Endangered Species Act) in Georgia and Florida, primarily from habitat loss and fragmentation, and Georgia state-listed threatened. Legally protected throughout its range. Tortoise-burrow sandhill landscapes are core recovery habitat; do not invent statutes or take exceptions from educational summaries.

In Georgia, non-venomous snakes are protected nongame wildlife under materials summarizing O.C.G.A. §27-1-28 (illegal to possess or kill many nongame species, including non-venomous snakes; misdemeanor penalties cited by DNR). Disturbing dens or homes of wildlife is also illegal (O.C.G.A. §27-1-30). Georgia DNR’s georgiasnakes overview names the eastern indigo and southern hognose as the two native snakes state-listed as threatened among species discussed there — indigo is also federally threatened. Report what DNR and USFWS state.

If you meet one

Do not approach, handle, collect, or attempt to relocate this animal. Identify from a distance and leave it alone. Casual relocation is not appropriate for a listed species. Report careful observations through Georgia DNR / recovery partners when useful. Local educators can help with distant photo ID and outreach without anyone touching the animal.

This species is not venomous. Protected status means leave-alone is both the safe and legal choice. Never pour gasoline or chemicals into holes (illegal under Georgia wildlife den-protection rules).
