| This movie starts just after a male Western Sagebrush Lizard ran up the face of a large a rock outcrop and tackled a huge female who is full of eggs and showing her orange breeding color. He continues to harass her and she moves slowly with her body and her tail elevated defensively. Then he settles in on a ledge above her while she rests. (She occasionally leaped after flying insects which landed nearby, but I could not get that on video.) |
A male Western Sagebrush Lizard in Contra Costa County runs between rocks, stopping to do his push-up display. This is the same male just before he ran up the rock and chased the female in the previous video. |
I followed a sagebrush lizard around one morning at my campsite with a video camera as it crawled over a large fallen tree, then foraged around eating small insects. |

| These three short videos show some interactions between a male and two gravid female Western Sagebrush Lizards on an afternoon in late June in the Sierra Nevada Mountains in Tulare County. In the first video, they are separated but the male jumps down to join a female and the third comes down from her rock, then as their shade disappears, they move into a sunny patch only a few feet away from the camera to bask. The other two videos show lots of push-ups, tail elevating, shuffling around, and even what looks like snuggling. |

| Description |
| |
| Size |
1 7/8 - 3 1/2 inches long from snout to vent (4.7 - 8.9 cm). (Stebbins 2003)
|
| Appearance |
A small lizard with small keeled and pointed scales overlapping on the upper surfaces of the body and limbs.
These scales are not as large as they are on other lizards of the genus Sceloporus.
The gular fold is incomplete.
The scales on the back of the thigh are mostly granular, not keeled (as they are on the Western Fence Lizard.) |
| Color and Pattern |
Color is gray or brown with dark blotches or irregular bands on the body and tail.
Stripes on the sides, visible on other subspecies of Sceloporus graciosus, are not distinct on this subspecies, being reduced to rows of blotches or only partly connected blotches.
There is usually a bar of black on the shoulder in front of the front legs and rusty coloring on the armpits behind the front legs and sometimes on the sides of the body and the neck.
Unlike the Western Fence Lizard - Sceloporus occidentalis, there is normally no yellow coloring on the rear of the limbs. |
| Male / Female Differences |
Males have a patch of blue color on each side of the belly and on the throat.
The blue throat and belly patches are separated by white.
Male postanal scales are enlarged, and the base of the tail is broader than on the female.
The throat is light blue mottled with white spots.
Sometimes the blue patch is reduced or even absent.
Some males may develop bright orange breeding coloring.
Females have little or no blue on the belly.
When breeding, females may develop orange coloring on the sides and neck and yellow underneath. |
| Young |
| Young lizards have little or no blue on the belly. |

| |
| Life History and Behavior |
Activity |
Diurnal.
Active spring through fall.
Hibernates during winter.
A good climber and jumper, able to quickly jump from rock to rock.
Lives mostly on the ground near bushes, logs, rocks, or brush piles.
Often observed basking on rocks and logs.
|
| Territoriality |
| Males defend their territory and try to attract females with a push-up display that exposes the blue throat and ventral colors. Sometimes the tail is also held erect. |
| Defense |
Escapes danger by running into rocks, rodent burrows, or brush or climbs up trees or rock outcrops.
The tail can break off easily, but it will grow back. The detached tail wriggles on the ground which can distract a predator from the body of the lizard allowing it time to escape.
More information about tail loss and regeneration. |
| Diet and Feeding |
| Eats a variety of small invertebrates, including ants, termites, grasshoppers, flies, spiders, and beetles. |
| Reproduction |
Females lay 1 or 2 clutches of 2 - 10 eggs from June to August.
|
| Habitat |
Lives in sagebrush and other types of shrublands such as manzanita and ceanothus, as well as open pine and Douglas Fir forests, mainly in the mountains (usually at higher elevations than the Western Fence Lizard but they coexist at lower elevations). In coastal redwood forests, lives along river bottoms. Prefers open areas with scattered low bushes and lots of sun.
|
| Geographical Range |
This subspecies ranges west of the Great Basin desert in California, south throughout the Sierra Nevada and Tehachapi mountains, the inner Coast Ranges and Diablo Range, and along the north coast and northern mountain ranges, continuing north into southern Oregon. Populations also occur in the Sutter Buttes and in the Santa Cruz Mountains.
The species Sceloporus graciosus occurs in California, Eastern oregon, central Washington, southern Idaho parts of Montana and North Dakota, in much of Wyoming, Utah, western Colorado, northwest New Mexico, northern Arizona, and in the Sierra San Pedro Martir of northern Baja California.
|
 |
| Elevational Range |
The species Sceloporus graciosus is found at elevations of
500 ft. to about 10,500 ft. (150 - 3,200 m) (Stebbins 2003).
|
| Notes on Taxonomy |
Three subspecies of Sceloporus graciosus are recognized in California:
Sceloporus graciosus gracilis - Western Sagebrush Lizard,
Sceloporus graciosus graciosus - Northern Sagebrush Lizard, and
Sceloporus graciosus vandenburgianus - Southern Sagebrush Lizard.
Sceloporus graciosus vandenburgianus has been described as a unique species, Sceloporus vandenburgianus.
"Chan et al. (2013, Zootaxa 3664: 312–320) found that the currently recognized subspecies of S. graciosus are incongruent with mitochondrial haplotype clades, which often exhibit relatively deep divergences between geographically proximate samples, and that S. graciosus is paraphyletic relative to S. arenicolus. Although these findings suggest that S. graciosus is in need of taxonomic revision, those authors did not propose any taxonomic changes."
(SSAR Herpetological Circular No. 43, 2017)
In 1991, Collins (1991,Herpetol. Rev. 22: 42–43) proposed recognizing S. g. vandenburgianus as a full species, - Sceloporus vandenburgianus. In 1997, Wiens & Reeder (1997 Herpetological Monographs 11: 1-101) followed Collins’ proposal but pointed out the morphological similarity and geographic proximity of S. vandenburgianus to populations of Sceloporus graciosus gracilis. In response, many researchers are awaiting further studies before elevating the taxon to full species.

The following conservation status listings for this animal are taken from the April 2024 State of California Special Animals List and the April 2024 Federally Listed Endangered and Threatened Animals of California list (unless indicated otherwise below.) Both lists are produced by multiple agencies every year, and sometimes more than once per year, so the conservation status listing information found below might not be from the most recent lists. To make sure you are seeing the most recent listings, go to this California Department of Fish and Wildlife web page where you can search for and download both lists:
https://www.wildlife.ca.gov/Data/CNDDB/Plants-and-Animals.
A detailed explanation of the meaning of the status listing symbols can be found at the beginning of the two lists. For quick reference, I have included them on my Special Status Information page.
If no status is listed here, the animal is not included on either list. This most likely indicates that there are no serious conservation concerns for the animal. To find out more about an animal's status you can also go to the NatureServe and IUCN websites to check their rankings.
Check the current California Department of Fish and Wildlife sport fishing regulations to find out if this animal can be legally pursued and handled or collected with possession of a current fishing license. You can also look at the summary of the sport fishing regulations as they apply only to reptiles and amphibians that has been made for this website.
This animal is not included on the Special Animals List, which indicates that there are no significant conservation concerns for it in California.
