This Desert Spiny Lizard watched me from a rock, ready to dart to cover if I came any closer. These colorful, relatively large lizards are a common sight in desert parks and stucco jungle around Phoenix.

This Ghost Anole was one of many anoles seen on a trip to the high forests of Guatemala.

A Gila Monster peeking out of its spring staging spot, just down the hill from where it spent the winter. It shares this spot with several other Gila Monsters, a handful of Western Diamondback Rattlesnakes, and the occasional tortoise. It will spend the majority of each day during the early spring doing, basically, this. Resting in partial sun, disappearing if predators approach, and waiting to head out in nest-hunting mode as soon as the time is right.

A Gila Monster I followed to a nest of cottontails. It took a while, but it ate all three of them that were in there. Amazingly, they all fit, and the lizard ambled off to rest under an overhanging root in the drainage. It was a good example of how the venom of Gila Monsters is not necessary for predation, as the venom played no apparent role in the capture or consumption of its prey.

A Gila Monster out and about on a spring day a couple of years ago. On mild days, these animals start to move away from often communal dens to springtime staging areas. They may take daily patrols, searching for nesting mammals and quail eggs. It’s common for hikers to report them on social media frequently within a few days’ time, usually in late February or early March, which is a reliable signal that the process has begun each year.

I spotted this young Gila Monster on an isolated rocky area surrounded by desert grassland. Gilas in this area can often have more black mottling than the banded version found elsewhere in the state. We took some photos briefly and let it be on its way.

A Chuckwalla surveys its vast domain, just north of the Grand Canyon. Here, these large herbivorous lizards take on a sandy, mottled color, making them harder to spot against the ground by predators flying overhead. For an observer at ground level, however, the shape of a vigilant lizards popping up from outcrops and boulders is much easier to spot.

These sideblotched lizards are common and found about everywhere. Even in urban Phoenix and Tucson, they can be seen running around on the maze of block walls and stucco. This one is particularly colorful, found in northern Arizona.
