One of several Southwestern Speckled Rattlesnakes drinking water from its hydrophobic scales after a surprise June rain a few years ago. These snakes group up, often alongside other species, to wait out the hottest, driest times of year. When a rare rain event does come, everyone comes out to soak and drink all they can. Regardless of the season, every chance to drink in Arizona may be the last one for months, and these events are not to be missed.
A red-hued Southwestern Speckled Rattlesnake from Phoenix, Arizona. Its red coloration is typical of the local phenotype, which may include many variations of reds, orange, purple, and all shades in between.
These snakes are common in popular hiking areas, but are not an issue for people. Considering the hundreds of people that visit area trailheads each weekend during the peak of these animals’ activity, bites are incredibly uncommon. Hikers can keep that status by staying on trails, not wearing headphones or texting while walking, and keeping dogs on leash (it’s the law, too).
A pretty orange Southwestern Speckled Rattlesnake from Yavapai County, Arizona. The oxidation in the surrounding rock shows why this snake is the color that it is. I got some photos and watched it crawl off in the direction it was headed.
This Southwestern Speckled Rattlesnake was resting on a small rise just below its aestivation den in Phoenix. She’s pregnant, and will stayed in the area most of the summer before moving up the hill to a rocky slope to give birth.
Southwestern Speckled Rattlesnake resting under a bush on a cool Spring day. With temperatures still in the low 50s at night, this snake sat out overnight waiting for prey to wander by, nearly a quarter mile from its den further up the bajada.
A Southwestern Speckled Rattlesnake found in the lower foothills of the Cerbat Mountains of Mohave County, Arizona.
Southwestern Speckled Rattlesnake sitting out in the early morning after a long night waiting for a mouse. It will have another chance for prey, as birds and lizards visit the hillside, possibly not noticing this orange “rock” perfectly situated in the landscape.
A Southwestern Speckled Rattlesnake hiding away on a dry May day. A site nearby will serve as an aestivation den a few weeks later, once temperatures were firmly in the triple digits each day.
A pink Southwestern Speckled Rattlesnake resting in rocks near the Rattlesnake Solutions office in the first morning sun, This snake uses the same area each year, showing up around June and leaving once aestivation is no longer necessary during the monsoon. Where it goes in the cooler months is unknown, but the tight site fidelity of this species is nearly absolute in most cases. This was in 2021, and if she survives another year, there is no doubt we’ll see her again in the same spot in 2025.
A Speckled Rattlesnake on a small, ridiculously hot Mexican island. In the sparse vegetation littered with bones of cetaceans and fish, these small rattlesnakes survive.
