A Grand Canyon Rattlesnake in the last light of the day in northern Arizona.

Up close with a Banded Rock Rattlesnake from the sky islands of southeastern Arizona. These small, mountain-dwelling rattlesnakes are quick to flee when found. A typical encounter for a hiker is a short buzz and a glimpse of the last half of its body sliding under a rock. The tiny black flecks you see in […]

A young Sonoran Sidewinder (Crotalus cerastes cercobombus) with a nice, clean pattern near Phoenix last year. These small rattlesnakes are very common in the right habitat, but rarely seen by hikers because of the nature of that same habitat.

This little American Alligator didn’t care much about my presence as it spent the morning lounging. Most, upon any kind of approach, slip silently away. Growing up in the West, I rarely miss an opportunity to take a picture of one when I can.

I saw this Mojave Rattlesnake (Crotalus scutulatus) crossing a dirt road near the U.S./Mexican border a few years ago in mid-elevation semi-desert grassland. Several other species can be found in the same band o transitional habitat, including Arizona Ridgenosed Rattlesnakes, Banded Rock Rattlesnakes, Western Diamondback Rattlesnakes, and Blacktailed Rattlesnakes. I escorted it off the road […]

A large Veracruz Neotropical Rattlesnake (Crotalus mictlantecuhtli) from a trip to Mexico a few years ago. This species was recently recognized as a separate lineage of the Neotropical Rattlesnakes, described in 2020, about a year before this photograph was taken.

This Red Eyed Treefrog from Guatemala looks a bit different than those I’ve seen in Costa Rica and Mexico.

Twin Spotted Rattlesnakes (Crotalus pricei) are small, high-elevation rattlesnakes that are found in a handful of mountain ranges in the Sky Islands region of Arizona and northern Mexico. They are occasionally seen by hikers on high saddles and trails, where they are quick to flee with a departing buzz. A person would really have to […]

This is one of several Sonoran Sidewinders (Crotalus cerastes cercobombus) we found near Phoenix a while back on a hot night. These small rattlesnakes are abundant in the right habitat. Still, they are rarely seen by hikers, because the flat, sandy soil of the Colorado River subdivision of Sonoran Desert is rarely a scenic destination […]

We were out checking dens on a spring day and stopped at one last spot. It was a rocky outcrop relatively isolated from the rest of the mountain, and looked great from at distance. Upon getting to it, we were immediately greeted with this large Western Diamondback Rattlesnake on the move a short distance from […]
