Sometimes fence lizards are very dark before they have warmed up in the sun, like this one. They can look like they're completely black at a distance. This can cause problems for some people trying to identify a lizard that doesn't look like a typical fence lizard they see in pictures.

In California, western black-legged ticks (deer ticks) are the primary carriers of Lyme disease. Very tiny nymphal deer ticks are more likely to carry the disease than adults. A protein in the blood of Western Fence Lizards kills the bacterium in these nymphal ticks when they attach themselves to a lizard and ingest the lizard's blood. This could explain why Lyme disease is less common in California than it is in some areas such as the Northeastern states, where it is epidemic.
|Two different species of lizards, an adult Skilton's Skink and a Coast Range Fence Lizard, were observed basking together frequently in a backyard garden in Marin County in April. This might represent a mate-guarding behavior by a male skink that confused the fence lizard with a female skink, or maybe they're just sharing a good basking spot, unconcerned about any threat from the other lizard.|

After release from capture, this lizard remained motionless in the position seen here for about a minute before turning over and running away.

Occasionally I receive pictures of similarly-colored spiny lizards, but I have not learned what causes the unusual color, whether it is a naturally-occuring aberrant coloration, or if it is artificially added somehow. You can see more pictures of orange or gold spiny lizards on this page.

|Two Coast Range Fence Lizards observed during the breeding season in early May in San Benito County. The first lizard, a female, has moved from her perch on a rock to a nearby rock in order to get away from the photographer. She begins a territorial push-up display when a male comes up the side of the rock and begins to pursue her. She arches her back and hops away in order to reject him. She may have already mated and is bearing eggs, or maybe he is not her type. He finally stops and does a push-up display, possibly to continue trying to entice her, or possibly to warn the photographer that this is his territory.||Two male fence lizards on the edge of a paved road in San Luis Obispo County size each other up for 20 seconds until one of them makes a move on the other starting a slight skirmish, that ends up as more of a test than a fight.

|A male Northwestern Fence Lizard defecates off the side of a Butte County fence, wipes himself off, then does a territorial push-up display.||I'm not going out of my way trying to film this behavior - I can only take what I get - so here we see another Northwestern Fence Lizard doing his business for the camera. It's like they're trying to tell me something.||A male Northwestern Fence Lizard fights with a female in Placer County © Rod||

||These two videos show a Placer County Northwestern Fence Lizard appearing to taunt a garter snake (a Mountain Gartersnake is my guess, because it lacks red.) The lizard keeps moving down towards the snake but when the snake moves towards the lizard, apparently trying to catch it for dinner, the lizard runs up the wall away from the snake. © Rod|
The following conservation status listings for this animal are taken from the November 2020 California "Special Animals List" and the November 2020 "State and Federally Listed Endangered and Threatened Animals of California" list, both of which are produced by multiple agencies and available here: https://www.wildlife.ca.gov/Data/CNDDB/Plants-and-Animals. You can check the link to see if there are more recent lists.
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 go to the NatureServe and IUCN websites to check their rankings.
This animal is not included on the Special Animals List, which indicates that there are no significant conservation concerns for it in California.
