Western Rattlesnake
Crotalus oreganus
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.
