Tiger Rattlesnake resting outside its aestivation den on a hot Phoenix summer night. These snakes are quite common in much of the area, though most hikers will never see one due to their secretive nature and effective camouflage. Even of those reported, a large number of them … if not most of them, end up […]

Rattlesnakes live in the highest areas of Arizona, often taking forms that defy what most residents would think possible.

An Arizona Black Rattlesnake in ambush in the first sun of the day. The flat rock is on the only, narrow path to a natural water hole – the only water in the region. Any small mammal wanting to visit it would have to jump across this rock. This is likely something this snake knows […]

Southwestern Speckled Rattlesnake sitting out in the early morning after a long night waiting for a mouse. It will have another chance for prey, as birds and lizards visit the hillside, possibly not noticing this orange “rock” perfectly situated in the landscape.

This is a very adaptable species, thriving in mountainous habitat from sea level to high mountains, in hot, […]

A Southwestern Speckled Rattlesnake hiding away on a dry May day. A site nearby will serve as an aestivation den a few weeks later, once temperatures were firmly in the triple digits each day.

One of many Indian Vinesnakes we found moving in low branches on a rainy night in Karnataka, India.

One of many Caucasian Sand Boas we found in Greece a couple of years ago.
