Salvadora hexalepis
No medically significant venom known
Salvadora hexalepis, commonly called the Western Patch-nosed Snake, is a slender, fast-moving colubrid found in arid and semi-arid regions of western North America. Non-aggressive and primarily diurnal, it feeds mainly on lizards and small vertebrates. It has mild oral secretions but no medically significant venom known; nonetheless, avoid handling any wild snake.
Pantherophis obsoletus
No medically significant venom known
Large nonvenomous colubrid native to central and western North America, commonly found in woodlands, forests, agricultural edges, and around human structures. Climbs well, feeds on rodents and birds, and helps control pest populations. Often active at night in warmer months; generally avoids confrontation but may vibrate tail, musk, or strike when threatened.
Crotalus oreganus
Venomous
Crotalus oreganus (Western Rattlesnake) is a medium-to-large venomous pitviper native to western North America. It inhabits diverse habitats from forests and grasslands to rocky outcrops and desert foothills. It is primarily nocturnal or crepuscular in hot months, feeds on small mammals, birds, and reptiles, and delivers hemotoxic venom that can cause significant tissue damage and systemic effects. Avoid interaction, keep pets and people away, and contact professionals for removal.
Juvenile venomous snakes can deliver medically significant bites, but the common claim that they are automatically more dangerous because they cannot control venom delivery is not supported as a general rule. Adult snakes usually have larger venom glands and can deliver a larger total amount.
Bottom line: Treat every suspected venomous snakebite as a medical emergency, regardless of the snake’s age.
Head shape alone is unreliable. Many nonvenomous snakes flatten or widen the head defensively, and viewing angle can change the apparent shape.
Bottom line: Do not approach a snake to inspect its head. Use multiple traits, location, and a safe-distance photograph.
Tourniquets can worsen tissue injury and are not recommended for typical United States snakebites. Emergency evaluation is more important.
Bottom line: Call 911 or Poison Control at 1-800-222-1222. Keep the person calm and do not cut, suck, ice, or tourniquet the bite.
Young copperheads can have a contrasting yellow or greenish tail tip used in caudal luring. It is soft and tapered, not a segmented rattle. The bright color usually fades with age.
Bottom line: Never move closer to inspect the tail. The feature is a clue, not permission to approach or handle the snake.
Several non-rattlesnake species vibrate their tails when threatened. Dry leaves can make the sound resemble a rattle.
Bottom line: A defensive tail vibration does not identify the species. Keep your distance.
