Abstract

This research was conducted in Tadho Village, Wolo Tadho Nature Reserve Area, Riung District, Ngada Regency, East Nusa Tenggara Province, from July to August 2023.

Observations were conducted on one individual Long-tailed Macaque (Macaca fascicularis) and its behavior was followed and recorded using One Zero Sampling. One Zero Sampling is the recording of the dominant behavior within the time interval of an observation session.

He results of the study found the number of plants that have the potential as a food source in the Wolo Tadho Nature Reserve area there are 15 types of plants known to be selected by long-tailed monkeys (Macaca fascicularis) as food. The most dominant vegetation types are Lamtoro (Leucaena leucocephala), Tamarind (Tamarindus indica L) and Mangrove (Rhizophora apiculata) and the daily behavior of long-tailed monkeys (Macaca fascicularis) which is often done is moving 31%. Many behaviors were Feeding 19%, Resting 16%, Grooming 15%, Foraging 8% Playing 9%. Rare behaviors were Agression 1% and Mating 1%. While the behavior that was not seen was Object Play 0%.
