Abstract
The fruit choice of a wild troop of Formosa macaque in Heng-Chun Tropical Botanical Garden was studied during October 1999 and September 2000. Feeding frequency was compared to the availability of different fruit species to examine their fruit choice. I investigated if the morphological and nutritional characteristics of fruits affect the fruit choice of Formosa macaque. Fruit which availability varies by seasons were the main dietary items of the monkeys. Two categories can be identified by electivity index: (1) over-selection species, such as Diospyros discolor, Ficus virgata, Ficus caulocarpa; (2)under-selection species, such as Ficus benjamina and Bischofia javanica. The monkeys had an opportunistic feeding strategy on Ficus benjamina and Bischofia javanica. The results suggested that the monkeys preferred fruits from large trees and with the ripe flesh pulp. However, effects of the morphological and nutritional characteristics of fruits on fruit selection was not apparent.
