We were eating lunch under a creosote when Danielle noticed a Desert Iguana on the ridge. We then saw it and another Desert Iguana do some push-ups at each other. One then climbed into this shrub and proceeded to eat the flower bud while the other (which was slightly bigger) seemed to be standing guard below the shrub. Totally sweet behavior observation, apparently reptiles do more than bite, musk and defecate on human hands. Anyone know what might be going on here? Do female Desert Iguanas also do push-ups? Was the bottom iguana guarding the other one? Were these two males? Why are there not many tomes dedicated to Desert Iguana behavior?
