An Arizona Black Rattlesnake resting in partial cover. These snakes spend a lot of time on the surface, hiding in and as shadows to evade detection by predators and prey.

Arizona Black Rattlesnake In The Sun
A large Blacktailed Rattlesnake from the southeastern corner of Arizona. These snakes can be beautiful – a high contrast black and yellow with rainbow iridescence in the sunlight.
Arizona Black Rattlesnake At Its Den
One of a few Arizona Black Rattlesnakes hanging out at an overwintering site, ready and waiting for the cold to come. This was photographed in the fall at high elevation, where rattlesnakes gather in sometimes large numbers to den together in deep retreats.
This species is what locals often mistakenly refer to as “Timber Rattlesnake”, which it is not. Timber Rattlesnakes are a real snake, however, but not closely related to this one, and not found in the Western US.
Western Diamondback Rattlesnake Basking Under Cover
A Western Diamondback Rattlesnake basking in partial cover. This is how rattlesnakes and other reptiles typically thermoregulate. Filtered light and conduction from nearby surfaces and substrate can help them tune in on the right temperatures to a fine degree, all while avoiding detection by predators and prey. This is also a reminder of why it’s best to stay on established trails and keep dogs on leash when hiking in the spring.
Arizona Black Rattlesnake from Mohave County, Arizona
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.
Blacktailed Rattlesnake From Central Arizona
A Blacktailed Rattlesnake from central Arizona. These snakes are often a green shade, leading to misidentification as a Mojave Rattlesnake (which, ironically, are seldom green in many areas). These are large rattlesnakes that live in mountainous terrain, commonly seen by hikers but rarely by homeowners.
Young Blacktailed Rattlesnake
A young Blacktailed Rattlesnake breaking position to hide in rocks. We’d accidentally disturbed it by showing up, but it held this pose long enough for us to back off and get a few photos. This is in a remote canyon far from any road, and being bothered by people isn’t a regular thing for the snakes here.
Great Basin Rattlesnake in Arizona
A Great Basin Rattlesnake from northern Arizona, showing off its sharply patterned face. These are a wide-spread rattlesnake species, found throughout the Great Basin Desert in the western US, and some transitional habitat with influence from Mohave and Sonoran deserts, and high-elevation pine forest. Personally, I think the rosy-cheeked variety often seen in the Arizona Strip are uniquely beautiful. This one was photographed and left alone to continue doing its rattlesnakey things.
Blacktailed Rattlesnake Morning Bask
A young Blacktailed Rattlesnake moving up from the rock wall where it lives to catch morning sun in southeastern Arizona. Structures like this provide a range of options, allowing the snake to very precisely control its temperature – warming when it needs to, and retreating to shade as the day gets hot.
Couch’s Spadefoot
Each year during the monsoon, these amazing little frogs show up. They’re often mistaken for poisonous toads due to their superficial similarity and typically green color. It’s a Couch’s Spadefoot, a small and harmless species that spends much of its time underground. Its name is literal: to help with the underground lifestyle, it has hard protrusions on each hind leg to help dig in.
They also have, unlike most amphibians, cat-eyes (this one has them wide open, however). If you see one, you can ignore it as it’s not at all dangerous, but still keep your dog from eating it.
