Abstract

The selection of optimal basking perches to achieve preferred body temperatures and avoid predation risks is one of the most important behavioral decisions that a lizard makes. We studied perch selection by the spiny-tailed Iguana (Ctenosaura hemilopha) in Baja California Sur where they bask on elevated cacti. The more important factor determiningcardon selection by iguanas was the presence of old woodpecker holes which could be used as refuges within the top 50 cm of a branch. Otherfactors are the height of the cardon, the presence of some other holes and the number of branches of the plant. These data suggest that predation risk is the strongest factor affecting the selection of certaincardons as basking structures by spiny-railed iguanas. Because the holes are mainly old woodpecker nests, the choice of a cardon as a refuge-perching sire has to be related to a prior selection by woodpeckers.
