Just before sunset, we found a Great Basin Rattlesnake crossing a road in northeastern Arizona. It was bothered for a few minutes while we took some photos.

Arizona Black Rattlesnake Below Its Den
An Arizona Black Rattlesnake from an exposed desert mountain hiding from the sun. This snake is entirely black, missing the lighter-colored bands that are usually retained by the species into adulthood. Above at the crest of the hill, an outcrop of basalt serves as its den, throwing rocks down the bajada between a spring and lower drainage. This snake was about halfway up, still in spring egress staging, eventually descending to the drainage below for the year.
Desert Kingsnake
In the southeastern corner of Arizona, kingsnakes look different than the black and white banded pets many people are familiar with. This Desert Kingsnake, as an example, of a more speckled, chain-link pattern and somewhat more colorful base color. This is, with much variation, similar to how they’ll look throughout the Chihuahuan desert, and much of the subtropical Sonoran.
Sonoran Sidewinder Near Phoenix
Sonoran Sidewinders can be incredibly common in the right habitat, but that doesn’t often put them in the path of homeowners in the Phoenix and Tucson areas. Of the six species of rattlesnakes that can be found at the native habitat contact zones, this species is the first to disappear whenever roads come in. They once spanned the entire Phoenix metro valley, found in the desert around the base of Camelback Mountain and as far north and east as Cave Creek and the foothills of Scottsdale. This one was found in an area that will become developed over the next decade, and this now dense population of snakes will likely disappear.
Arizona Black Rattlesnakes At A Multi-Species Den
A pair of Arizona Black Rattlesnakes take the prime spot at the den, with a half dozen or more shuffling throughout the day behind them. For these snakes, it’s early den egress time, when they stage at and near the den for awhile before heading out for the season. This den is shared by two other species of rattlesnakes, though, all using the rocky area slightly differently. These are the last to emerge, with the Western Diamondback Rattlesnakes and Blacktailed Rattlesnakes having already dispersed for the year.
This was photographed in the late Spring several years ago in southeastern Arizona.
Southwestern Speckled Rattlesnake in Orange Form
Southwestern Speckled Rattlesnake on the move late at night in Phoenix. These snakes are the most commonly encountered snake on many trails in the area. For the reasons you can see here, and others, these snakes are quite often misidentified as Tiger Rattlesnakes when people see them. At popular trails like Piestewa (not where this one was), they’re seen about every night, even on very busy paths. But, contrary to how people often think of rattlesnakes: bites are nearly unheard of in those situations.
Arizona Black Rattlesnake From Greenlee County
An Arizona Black Rattlesnake from the far-eastern end of their range. This species’ appearance can vary from entirely black to light shades of grey and purple and change color from day to day. Many grow into adults that aren’t black at all.
From some areas, they may look strange. But, this may be only bias – most of the photographs you’ll see online of Arizona Black Rattlesnakes are from a handful of locales, and not representative of the phenotypic gamut of the species. The range where this one was found, in particular, has relatively few records of rattlesnakes on the books compared to the rest of the state.
Northern Blacktailed Rattlesnake in a Tree
I spotted this Northern Blacktailed Rattlesnake (Crotalus molossus molossus) resting about 4′ up in a tree on a hike in Yuma County, Arizona. Being up there can serve many purposes, from getting some cooler air on the belly to better hunting opportunities. This snake was likely hunting, waiting for one of the small birds and lizards common in the area to make its last mistake.
Blacktailed Rattlesnake at the Den
A Blacktailed Rattlesnake resting in the filtered light of a dense bush. This is one of many seen at a relatively densely populated den, at which we only found blacktails. Just down the hill, Western Diamondbacks also made an appearance. With some “up” left in the mountain and a change to more high elevation juniper habitat, we’re hoping for the addition of other rattlesnake species.
Red Southwestern Speckled Rattlesnake
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).
