Desert Spiny (Sceloporus magister) Lizard — Image by kenne
These are medium to large lizards with snout-vent lengths ranging from 2¼ to 5¼ inches (63 to 138 mm).
These robust lizards have keeled, pointed scales. Background color is usually subdued gray, tan, or blue
with a striking wide, purple stripe down the back and single yellow scales scattered on the sides (S. magister),
or scattered turquoise scales mixed with tan and brown on the back and sides (S. clarkii). Both species have a
dark collar under or around the neck; males have vivid blue throats and under-bellies. Females develop
orange to red heads during the breeding season. — Source: Arizona-Sonora Desert Museum

The mountain spiny lizard is the cousin of the desert spiny, whose coloring blends more with the desert than the mountain forests.

We have been experiencing some warmer spring weather here in the desert,
so more lizards are on the move

It’s hard not to think of lizards when one thinks of the hot desert days of summer.
Most lizards like the heat, but not to much.
An article in the Smithsonian Magazine notes,
“Scientists worry that a warming climate may be especially dangerous for lizards,
which aren’t able to regulate their own temperatures.”
Scientists are making use mitochondrial DNA to map out a species’ genetic diversity
to learn how animals might best adapt to global warming, if at all.
Lizards “may need to become nocturnal if they want to survive.”
Still, I’m always amazed to see a Zebra-tailed lizard moving across a neighbor street (black-top)
in the bright sun knowing that the air temperature is already in the triple digits
— go figure!
