Abstract
Abstract
The foraging behavior of Gekko gecko was observed at the visitor complex of
the Khao Khiao Open Zoo at the Khao Khiao-Khao Chomphu Wildlife Sanctuary in
Chon Buri Province, Thailand. Foraging parameters of G. gecko (foraging
period, time spent moving, foraging attempts, foraging success, prey size
consumed, and foraging distance) did not vary significantly between males,
females, and juveniles. Individuals foraged between 18:01 and 09:00 hrs.
Peak emergence time was between 18:01 and 20:00 hrs. Peak retreat time was
between 04:01 and 07:00 hrs. Major food items included insects of the orders
Lepidoptera, Orthoptera, and Coleoptera. Prey sizes of males, females, and
juveniles were not significantly different, indicating no prey size
selection. This may have been due to low insect availability in the habitat.
Gekko gecko tended to be a sit-and-wait forager spending most of the time
waiting for active prey. However, it sometimes foraged more actively when
insect abundance was relatively high. Foraging behavior of males tended to
be more variable than females and juveniles. In addition, variation in
foraging parameters among individuals was noted. Foraging strategies of G.
gecko observed in this study are interpreted in the context of optimal
foraging theory.
