Banded Rock Rattlesnake Up Close
Up close with a Banded Rock Rattlesnake from the sky islands of southeastern Arizona. These small, mountain-dwelling rattlesnakes are quick to flee when found. A typical encounter for a hiker is a short buzz and a glimpse of the last half of its body sliding under a rock.
The tiny black flecks you see in the scales aren’t really visible in real life, or even visible at all. They show up on camera sensors, though, for some reason. Similarly, it’s often difficult to capture the colors of the species on camera … a snake with a bright green stripe down its back may appear to be without it on camera.
Young Sonoran Sidewinder
A young Sonoran Sidewinder (Crotalus cerastes cercobombus) with a nice, clean pattern near Phoenix last year. These small rattlesnakes are very common in the right habitat, but rarely seen by hikers because of the nature of that same habitat.
Mojave Rattlesnake in Arizona Grassland
I saw this Mojave Rattlesnake (Crotalus scutulatus) crossing a dirt road near the U.S./Mexican border a few years ago in mid-elevation semi-desert grassland. Several other species can be found in the same band o transitional habitat, including Arizona Ridgenosed Rattlesnakes, Banded Rock Rattlesnakes, Western Diamondback Rattlesnakes, and Blacktailed Rattlesnakes. I escorted it off the road before it was killed by border patrol vehicles.
Veracruz Neotropical Rattlesnake in Mexico
A large Veracruz Neotropical Rattlesnake (Crotalus mictlantecuhtli) from a trip to Mexico a few years ago. This species was recently recognized as a separate lineage of the Neotropical Rattlesnakes, described in 2020, about a year before this photograph was taken.
Twin-Spotted Rattlesnake in Arizona
Twin Spotted Rattlesnakes (Crotalus pricei) are small, high-elevation rattlesnakes that are found in a handful of mountain ranges in the Sky Islands region of Arizona and northern Mexico. They are occasionally seen by hikers on high saddles and trails, where they are quick to flee with a departing buzz. A person would really have to pick one up or be hiking barefoot to get bitten by one, if they’re even lucky enough to see one or have it stick around long enough for that to happen.
Sonoran Sidewinder Near Phoenix
This is one of several Sonoran Sidewinders (Crotalus cerastes cercobombus) we found near Phoenix a while back on a hot night. These small rattlesnakes are abundant in the right habitat. Still, they are rarely seen by hikers, because the flat, sandy soil of the Colorado River subdivision of Sonoran Desert is rarely a scenic destination for hikers.
Western Diamondback Rattlesnake at a Den
We were out checking dens on a spring day and stopped at one last spot. It was a rocky outcrop relatively isolated from the rest of the mountain, and looked great from at distance. Upon getting to it, we were immediately greeted with this large Western Diamondback Rattlesnake on the move a short distance from what we’d later recognize as the entrance.
Prairie Rattlesnake Den in Arizona
It takes a lot of patience to sneak up on this den of Prairie Rattlesnakes in northern Arizona. Unlike most rattlesnake dens I visit, these spook incredibly easily, retreating at the sight of me from well over 100′ away. Even when moving slowly, they seem to recognize the threat and disappear … for the rest of the day. It’s only by arriving before it’s warm enough to emerge and hiding behind boulders that it was possible for me to get these photos, and watch their actions for the morning.
These small variants of the species were once considered a separate subspecies (Hopi Rattlesnake), more than twenty years ago, but may be again, based on discussion of new research from reliable sources. These are all only around 1 to 1.5′ long, and will never get bigger. This is quite different than the much larger, greener (~3′) versions of the same species found in the Juniper-dominated hills, a relatively short drive away.
This topic will almost certainly mean the comments here will be dominated by snake people, similarly emerging from the crevices of the internet to shake fists in various directions. Taxonomy is a bit like music – whichever bands were popular at the time a young herpetologist is most active seem to become the prime lexicon, all future versions to be summarily dismissed as noise of youth.
