33 round tailed horned lizard skulls found while cleaning out an America Kestrel nest box.
“My wife and I have a place in the Chiricahua Mtns of SE Arizona. I have a Kestrel nest box there. This spring the Kestrel pair raised 5 young in the box and after they were through nesting I cleaned out the box to get it ready for next year. The only bones in the box were 33 Round-tailed Horned Lizard (Phrynosoma modestum) skulls, which I placed in my palm and photographed.”
