An Arizona Ridgenosed Rattlesnake in habitat on a humid monsoon morning in southeastern Arizona.
A Southwestern Speckled Rattlesnake in ambush on a humid night a couple of years back. Like many other desert reptiles, the monsoon and period after are the most active times of year. Humid air and cooler, stable temperatures make for safer activity, and a lot has to be done in a relatively short amount of time.
Southwestern Speckled Rattlesnake (Crotalus pyrrhus)
An Arizona Ridgenosed Rattlesnake spotted late on a humid monsoon night in southeastern Arizona. This is the state reptile, though relatively few Arizona residents will ever see one.
An Arizona Black Rattlesnake from the western end of their range. Locals in the area often refer to them as “timber rattlers”, though actual Timber Rattlesnakes are a distinct species that is not found in the western states. This one was found on a relatively cold, rainy weekend in August, active on the surface just before the area was saturated.
