A Tiger Rattlesnake found on a nighttime hike in Phoenix more than a decade ago. These snakes are, unfortunately, often poached from preserves.

A Great Basin Rattlesnake spotted in southwestern Idaho during den egress (leaving). I didn’t mean to disturb this one, but it saw me before I saw it, and this is how that goes. Obviously, though, these aren’t aggressive animals and it was very easy to just walk away.

A colorful Blacktailed Rattlesnake from the southeastern corner of Arizona.

A Grand Canyon Rattlesnake found near its namesake a few years ago. This one is still pretty sharply patterned for a snake of this age.

The face of the Arizona state reptile, an Arizona Ridgenosed Rattlesnake found in the Madrean oak grasslands of the sky islands. These small snakes rattle is reduced to sound more like an insect than what most expect from a rattlesnake. Despite being common, most of the ranchers and residents in the area that I’ve spoken with over the years have never heard of it – a testament to its cryptic lifestyle.

I found this Blacktailed Rattlesnake with a few others hanging out around a winter den early in 2024. Unlike other rattlesnake overwintering sites in the area, this one does not seem to be shared with the other rattlesnake species that can be found there – just lots of blacktails.
Dens like this have been difficult to pinpoint in environments that are mostly open rock, but over time the specifics have become more apparent and sights like this come easier these days. I’m looking forward to a return visit this spring.

A baby Indian Cobra we found along a canal in Bangalore, India. This little one was so small you could see its heard beating through its belly. Turned away, it’s doing its best to tell us to get lost. After a few photos, we did.

I’ve been watching this old Arizona Black Rattlesnake for more than 10 years now, each year returning to the same location to hunt for small animals looking to get a drink at an isolated water hole. The rock wall built by ranchers long ago serves as perfect daytime refugia.

A group of Western Diamondback Rattlesnakes aestivating during the lethal Arizona summer heat in the summer of 2016. In this cave, they can stay consistently cooler than the 115˚F+ daily temperatures outside and survive until monsoon rain brings relief.

I spotted this Central American Boa crawling along the upper edge of an eroded dirt wall in southern Mexico a few years back. It was a young boa, maybe 4 feet long. It seemed pretty busy searching along the vegetation transition, and allowed some easy photos.
