Western Diamondback Rattlesnakes are the most common rattlesnake in the Phoenix and Tucson areas, and likely the most encountered snake overall. This isn’t necessarily due to abundance alone – they’re large, noticeable, and can be noisy. This one, however, thought it wasn’t seen, and remained in this coil in wash sand until after I left.

A Lowland Striped Blindsnake from Guatemala. It’s a tiny, entirely harmless invertebrate specialist that doesn’t spend much time on the surface, so we were lucky to see one. Compared to the unicolor blindsnakes (Rena sp.) from the U.S., this one having some pattern and a bright yellow tail spine was very interesting. The thing they […]

Crossing a metal bridge on a trail through the Costa Rican rainforest, we were stopped by the sight of a Blunt-headed Tree Snake in the latter stages of eating a small lizard. The lizard was still trying to escape, but the snake was not going to lose this one. These tree snakes, with their huge […]

A Fer De Lance found resting in the center of the trail a short distance from camp in the Peruvian Amazon earlier in the year. The color and chaotic pattern of this snake would make it easy to miss, which could be a fatal mistake in the remote location we were at.

A small viper from the relatively dry tropical forests of Pacific coastal Costa Rica. This Slender Hognosed Pit Viper was found crossing a path late at night. They are common in the area, and in good conditions, dozens can be seen in a single night.

An especially bitey Rainbow Boa was found cruising around in the leaf litter between amazingly large trees in the Amazon. These snakes are popular in the pet trade, for obvious reasons. In the wild, they’re quick to defend themselves, understandably. I got some photos and watched it slide off into the darkness.

One of several baby Arizona Black Rattlesnakes laying around outside a winter den earlier in the year. As this snake matures, it will likely darken to mute the contrast shown here and be nearly entirely black, like the other females present in the rocks behind it.

This Regal Horned Lizard decided that basking right in the middle of a busy road was a good idea. It wasn’t. But from the look on its face, my moving it to an anthill a short distance away was not appreciated.

It’s not a great photo, but this is how these snakes are often seen. It’s a Striped Whipsnake; one of several seen cruising around a multi-species rattlesnake den in the spring. Personally, I’ve been clued into a good number of rattlesnakes hidden deep within crevices because of these much more observable snakes, and their preference […]

The first of a handful (not literally) of Central American Eyelash Vipers I found on a family vacation a couple of weeks ago to Costa Rica. This blue-greena nd pink individual stayed the entire week on the same tree, moving lower at night to hope for prey. On the last day, a massive rainstorm got […]
