With high temperatures in the 50s these days, you wouldn't expect to see many lizards. The smaller ones are more likely to be out, though, as they warm up more quickly (more surface area relative to volume).
On Ned's Nature Walk, William, a newcomer to Tucson, noticed the ant hill (bottom right of photo shows opening) and then the "moving stone." We had to get close to pick out this tiny Regal Horned Lizard, patiently waiting for lunch to crawl down from the hill.
