Greater roadrunner (Geococcyx californianus), in the Hedgpeth Hills, Thunderbird Conservation Area, Glendale, Arizona.

During mating seasons roadrunners leave the ground for exposed perches on rocks or open branches of trees, to establish territories and improve visibility to potential mates. Or maybe they just want their pictures taken. 

Common side-blotched lizard (Uta stansburiana ♂), in the Thunderbird Conservation Park in Glendale, Arizona.

This fellow was doing little lizard push-ups on his stone perch – a fearsome territorial display among his kind, but really amusing to me. I could watch for hours.
