Arizona Black Rattlesnake giving me a reminder to keep my distance and leave it alone. I spotted this one crawling from a small drainage back to tangled debris at the base of a sycamore in southern Arizona.

Blacktailed Rattlesnake showing off the “desert phase” phenotype, typical of lower, hot desert regions where this snake is common in rocky hills and mountains. This chaotic pattern can range from a yellow-green to silver, at times with the pattern degrading to the point of a unicolor appearance. This one is typical for mountains west of Phoenix.

Sonoran Lyresnake from the eastern end of Arizona. These are secretive snakes that live on rocky hillsides, eating lizards and small mammals. They are mildly venomous, and can cause a reaction in humans, but typically not considered dangerous. Fortunately, a bite can easily be avoided by just leaving these shy animals alone.

Rattlesnakes live in the highest areas of Arizona, often taking forms that defy what most residents would think possible. This one, an adult Twin-Spotted Rattlesnake (Crotalus pricei), is only about 20″ long as a mature adult, with a narrow head, tiny rattle, and body pattern that convergently looks just like a harmless nightsnake.
These are one of the four species of rattlesnakes in Arizona that are protected by law from any kind of disturbance, thankfully.

An Arizona Black Rattlesnake in ambush in the first sun of the day. The flat rock is on the only, narrow path to a natural water hole – the only water in the region. Any small mammal wanting to visit it would have to jump across this rock. This is likely something this snake knows very well by now, an example of how much can go into the selection of a hunting position. If I may anthropomorphize a bit, I’d call it strategic.

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.

This tan Blacktailed Rattlesnake was spotted on a night hike in the Harquahala mountains of western Arizona. In the low desert, they look quite different than the typical yellow and black Blacktails we often post photos of. This is a very adaptable species, thriving in mountainous habitat from sea level to high mountains, in hot, dry deserts to relatively cool pine forest and all in between.

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 Western Diamondback Rattlesnake cruising along a dry wash on a hot summer evening. Nearby water means a higher number of rattlesnakes in the area, and they can be found each evening moving to and from the spring. Not only good for a drink; these situations are ideal hunting opportunities for prey who also need it.
