Gopher Snake

Pituophis catenifer

Often mistaken for a rattlesnake due to its bold patterns and defensive hiss, the Gopher Snake is actually a harmless, rodent-eating ally for any gardener. These impressive constrictors are one of the most beneficial and widely distributed reptiles in North America.

Where Does the Gopher Snake Live?

Native to North America, the Gopher Snake occupies a massive geographic footprint that stretches from the southern provinces of Canada all the way to central Mexico. It is most prevalent throughout the Western United States, ranging from the Pacific Coast across the Great Plains. These snakes are incredibly hardy, thriving in environments as varied as the arid Mojave Desert, the coastal scrub of California, and the high-elevation meadows of the Rocky Mountains.

Behavior

Gopher Snakes are one of the most commonly encountered reptiles in North America, known primarily for their impressive defensive displays. When threatened, they perform a convincing rattlesnake impersonation: they flatten their heads into a triangular shape, hiss loudly, and vibrate their tails rapidly against dry leaves or grass to create a buzzing sound. Despite this tough exterior, they are nonvenomous and generally reluctant to bite humans unless significantly provoked.

As powerful constrictors, they are solitary hunters that spend much of their time underground in rodent burrows or prowling through tall grass. They are diurnal, meaning they are most active during the day, though in the scorching heat of mid-summer, they often shift their activity to the cooler twilight hours or even become nocturnal. In the winter, they retreat to communal dens (hibernacula) to brumate until spring.

Camera Tips

Capturing a Gopher Snake on camera requires a different strategy than scouting for mammals. Since snakes are cold-blooded, traditional Passive Infrared (PIR) sensors—which trigger based on heat signatures—can sometimes fail to detect them against a warm ground surface. To improve your chances, place your camera in 'Time-Lapse' mode with short intervals (every 15-30 seconds) during the peak morning and late afternoon hours when they are most likely to be moving.

Position your camera at ground level, angled slightly downward. Snakes are creatures of habit and edge-dwellers; they prefer to travel along 'corridors' where they feel protected. Place your camera along the base of a garden wall, the edge of a tall grass line, or next to a woodpile. If you have a 'drift fence' (a low temporary barrier), snakes will often crawl along its length, making it the perfect spot for a clear side-profile shot.

Focus your efforts near potential 'basking' sites and hunting grounds. Flat rocks that catch the morning sun or the entrance to active rodent burrows are high-traffic areas. Because Gopher Snakes are large and move relatively slowly while foraging, you don't need a super-fast trigger speed, but high-resolution video can help you distinguish their unique scale patterns and behavior.

Frequently Asked Questions

Gopher Snakes are primarily diurnal, meaning they are most active during daylight hours. You are most likely to see them basking in the sun during the mid-morning or hunting for rodents in the late afternoon. During the hottest parts of summer, they may switch to crepuscular activity, moving around at dawn and dusk.

To attract Gopher Snakes, create a reptile-friendly habitat by leaving some areas of your yard 'wild.' Rock piles, log heaps, and tall grass provide essential cover and hunting grounds. Avoid using rodenticides, as Gopher Snakes are natural pest controllers; having a healthy population of mice or gophers is the best way to ensure these snakes stick around.

Gopher Snakes are carnivores and highly skilled hunters. Their diet consists mostly of small mammals like pocket gophers, voles, mice, and ground squirrels. They are also known to climb trees to eat bird eggs or nestlings and will occasionally consume lizards or smaller snakes.

Yes, Gopher Snakes are very common in suburban environments, especially those near open fields, parks, or canyons. They are highly adaptable and often live in residential gardens where they help control rodent populations, though they usually remain hidden under bushes or in crawl spaces.

While both have blotched patterns, Gopher Snakes have round pupils, a narrower head, and lack the distinctive rattle at the end of their tail. Additionally, Gopher Snakes have a dark line running from their eye to their jaw, and their scales are 'keeled' (ridged), whereas many rattlesnakes have a more heavy-bodied, thick appearance.
