2. Sagebrush Lizard

The sagebrush lizard grows from between 1.9 and 3.5 inches or 4.7cm to 8.9cm from snout to vent. Hatchings are only around 2.5cm.
They are similar in appearance to the western fence lizard, just smaller with more scales.
These lizards are brown, gray, or olive in color with blue or green on the surface. It’s not uncommon for these reptiles to have an irregular pattern on the tail and body. They have a black bar that runs on the shoulders with lighter lines on both sides.
Females tend to have a yellow or white belly, while males have blue patches on their throats and bellies. Males develop orange coloration during the breeding season.
These lizards are usually found in a host of habitats from forests to woodlands to shrubland. They enjoy laying in the sun and basking on rocky outcrops and logs.
When scared, they will reach for rocks, trees, or crevices in order to hide. They tend to brumate (hibernate) in the winter months.

3. Side-blotched Lizard
Scientific name: Uta stansburiana.
Common name: Side-blotched lizard.
These lizards are small lizards with males only growing up to 2.4 inches (6cm) from snout to vent.
Females are slightly smaller. Some of the males will have blue flecks which can be seen on their tails and backs with yellow or orange on the sides, while others remain unpatterned. Females have stripes on their backs and sides but may not have any patterning.
Males are aggressive and very defensive of their territory.
Tail length plays a role in the dominance hierarchy within this species. A reduction in tail size in males and females will be a loss of social status.
4. Western Fence Lizard

The Western fence lizard can grow up to 8.9cm from snout to vent with a total length of approximately 21cm with the tail.
They tend to be black or brown in color, though it’s not uncommon for them to have some green in their coloration with black stripes on the back.
The bright blue belly is what really sets these lizards apart. They have yellow in the ventral side of the limbs with blue patched throats.
Females are not as bright in color, neither are juveniles. Males can display a bright turquoise blue color with some spots on the surface.
These lizards enjoy a host of habitats and can be found in sagebrush, woodland, farmland, grasslands, and more. They do avoid a harsh desert environment and prefer being close to water. They are often seen lying on the paths and rocks, even fence posts soaking up the sun.
They change their color from a tan or light gray to black, which helps them absorb the sun’s UV rays with ease.
5. Western Skink
Scientific name: Plestiodon skiltonianus.
Common name: Western skink.
The Western skink is an agile and secretive lizard that you will see scurrying through leaf litter and vegetation.

These skinks can easily be distinguished from other skinks for the broad black or brown band that starts on the head and extends just past the hind legs.
Adults have a broad stripe down their back which is edged with black and bordered on both sides in a white/beige color. A second stripe starts on the upper jaw separated by the broad dark band. Juveniles have bright blue tails that turn gray as they age.
