The study on aggressive behavior of long-tailed macaques has been conducted from May to July 2016 at Gunung Meru, Padang, West Sumatra. This study aimed to compare between provocated and non-provocated aggressive behaviors of the macaques toward human visitors at Gunung Meru feeding site. This study used all-occurrence sampling method to record aggressive interactions from the macaques along the visitors behavior. One or more visitors were followed for ten minutes at the monkey feeding ground for a total 78.5 hours. The aggressive behaviors of long-tailed macaques either provocated or non-provocated were considerably high intensity level, including body contact and biting. Feeding contexts (i.e. food exposure, feeding, and contact feeding) become the main situation resulting provocative aggressions. This study suggest that monkeys and human visitors have a potential close contact and could be pathogen transmission.

This study used point count method along a survey routes from 1300 to 2700 m asl, which is divided into three zones (Zone I: 1300 - 1800 m asl, Zone II: 1800 - 2200 m asl and Zone III: 2200 - 2700 m asl). This study recorded 216 individuals of 38 bird species to 21 families and 9 orders. The highest species diversity and richness was in Zone II. Zone III had low richness and low species diversity but the presence of bird is more evenly distributed. Most of the endemic bird species at Mount Singgalang was found at Zone I (1300 to 2300 m asl). Species richness decreases along increasing the altitudinal zonation of Singgalang Mountain.Key Words : Altitudinal zonation, community, bird, Singgalang Mountain
