2 lizards with 2 different posturings. This one is puffed up vertically and curls the tail. It moved up and down with each step, not the pumping the front like the other.
This one has less markings on the back but blue and black markings down the sides and under the throat. Couldn't find info on male vs female or various posturing. If you have links please share as i would like to know more about their rituals. This one only did the pumping of the front end and ran normal.
Several in mowed but mostly forb filled unbuilt lot between houses
Yard, resting on helianthus annuus, the smaller green one
Yard, perched on fleabane stem
