      Abstract

      Spectral tarsier (Tarsius spectrum) is one of endemic primate species in Sulawesi Island. Tarsiers are very small in size and nocturnal in their habits in North Sulawesi, they are found in several habitat types, for example: primary and secondary tropical forests, mangrove, scrub, mountain habitat, and farming areas. They are mainly insectivorous animals, so they can play a role in pest control in farming areas. They are considered as beneficial to farmers because of their present. In a conservation perspective, estimation of their density outside of forest is important to analyse. Therefore easy and fast sampling, techniques and necessary. Duet call is a vocalization released by a pair of adult male and female at every early morning and this behavior can be utilized as the sign for group location for density determination of this species. The technique used was vocalization as group representation and square plots within 100 m in radius. Every early morning an investigator stays at the center of one plot and counts the total of duet call location. The average group sixe was 4,01x 1.83 individuals per plot. The formula for counting the are density was. Tarsier Density = (Total Duet Call x 4,01) individual / 3.14 ha.
