A Western Diamondback Rattlesnake I found in ambush on a late-night hike in a desert canyon. When it’s hot, these snakes are mostly nocturnal, only seeing daylight shortly after sunup for much of the summer.

An Arizona Black Rattlesnake from southern Arizona. Even though I’m only in this location once or twice each year, I have seen this one several times over the last decade. There’s a small rock pile next to a log that it spends much of the summer making small movements around, and it was good to see it again as a little bit older, larger version of the last sighting a few years prior.

A Southwestern Speckled Rattlesnake from the Phoenix area. This species of snake has a huge gamut of colors and patterns possible throughout its range. Even within relatively nearby locales, it can be extreme. Just about ten miles from where this snake lives, they are red or orange.

Cerralvo Island Rattlesnake from Baja California Sur, Mexico several years ago. There are a couple of species of rattlesnakes on this island, both of which can be found even down on the beach, in ambush alongside seashells and dolphin bones.

A Southwestern Speckled Rattlesnake from the Phoenix area. In some locations, they can be a pretty brick red like this one. These are the second most commonly encountered rattlesnake by hikers in the central Phoenix parks.

A Banded Rock Rattlesnake from southeastern Arizona. These snakes are typically quick to rattle and flee into cover. But due to their small size, it can sound more like an insect than a rattlesnake. Despite being common and locally abundant, there is little chance of an accidental bite to anyone not purposely trying to capture one.

A Western Diamondback Rattlesnake I found eating a rodent. Which order of these animals do you think kills more people in any given year in the US?

A Southwestern Speckled Rattlesnake hanging out in a drainage, as it does about every morning, during the lethally hot period of Arizona summer. For much of the year, rattlesnakes are largely nocturnal, encountered by hikers and homeowners only just after sunup and again after dark.

A Great Basin Rattlesnake from one of the most remote areas of northwestern Arizona … the kind of place that sees more low flying helicopters than trucks. These snakes, as juveniles, have crisp lines and blotches that look similar to other rattlesnakes of the Western Rattlesnake complex. As they mature, however, the pattern often disintegrates into these messy blotches.

We found this little Great Basin Rattlesnake in extreme northern Arizona. The Great Basin Desert is one of FOUR desert regions that converge in Arizona, each bringing diversity of rattlesnakes and other wildlife to the state. If you’re ever wondering why Arizona has more rattlesnakes than anywhere else, that single fact is a major factor.
