I saw this lizard clinging to the patio screen outside today. I walked out to get a photo of the little red-headed guy. We later tried to look up on the Arizona Lizard website, but couldn’t find a match. It looks like the spiny lizards we see around here once in a while, but this is the first time we have seen a red-faced spiny lizard. Click on the image to enlarge.
Update: Hat tip to Glenn B who points out in comments that this is likely a female spiny lizard whose head has turned red for breeding season.
