Western Rattlesnake

Crotalus oreganus

☀️

Active

Summer

The Okanagan's only venomous snake and one of its most misunderstood residents. Western Rattlesnakes are shy, slow-moving, and want nothing to do with people — they bite only as a last resort when cornered or accidentally stepped on.

Field Note

A rattlesnake adds a new rattle segment each time it sheds its skin — but segments break off over time, so the rattle can't tell you how old the snake is.

📍

Where to Spot It at ABNC

Warm rocky outcrops, south-facing slopes, and brushy areas — especially May through September. Always watch where you step and never reach under rocks or logs.

💚

Why It Matters

Rattlesnakes are important predators of small mammals like mice and voles. They are a Species at Risk in BC and are legally protected.

🧒

Good to Know

Rattlesnakes shake their tail rattle to say 'please back away!' They're not mean — actually quite shy. If you see one, stop, stay calm, and walk around it giving plenty of space.
