Common Garter Snake
Thamnophis sirtalisAlso known as Garden Snake, Striped Snake
Common garter snakes emerge from subterranean hibernacula every spring, forming dense mating groups near winter den sites. Their yellow or greenish longitudinal stripes provide effective camouflage in dense vegetation as they hunt earthworms and amphibians during the day. Highly adaptable, these snakes thrive across a vast range of North American landscapes, from suburban lawns to wild mountain meadows.

- Harmless to humans, though cornered individuals may bite or release a foul-smelling musk.
Responsible observation
- Observation: Watch quietly from a short distance while they bask in sunlit patches along trails or gardens.

- Garden Benefits: Maintain brush piles and native ground cover to encourage natural pest control.
