Individuals of a species use habitats on different ways for refuge, feeding, reproduction, or perching. We studied the variation on perch use between sex and age classes of Anolis polylepis at the Piro Biological Station, Costa Rica. Our results point to a similar perch use pattern between sex, but different between age classes, considering only the lowest and
highest perches. Adult females and males use herbaceous and shrubby vegetation and avoid leaf litter. Juveniles use herbaceous vegetation and leaf litter, but avoid shrubby vegetation. We suggest that adult males use higher perches to defend territory.
Conversely, juveniles use lower perches to avoid predators and foraging. Adult females use middle and high perches. This result is in contrast with previous studies on this species.
