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 […]

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.

Northern Cat-eyed Snake from late last year. This animal is found in thornscrub and tropical forest habitat throughout much of Central America, and just barely makes it into the United States, in south Texas.

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.
