The aim of this research was to determine the importance of feed availability to herbivorous bird community. The research was conducted by comparing the diversity of herbivorous bird at four sites with different feed plant abundance at Bantimurung Bulusaraung National Park. The first site was core zone with old-growth forest. The second site was wilderness zone with the secondary forest that bordering with community settlement. The third and the fourth sites were rehabilitation zone with abandoned community garden which differs in the composition of vegetation. The population of birds was collected using point count method and the feed plant species was collected using systematic quadrat sampling method. Data of bird population was analyzed using Shannon-Wiener diversity index, Pielou Evenness index and Simpson dominance index. The significance different between the number of bird individual was tested using Kolmogorov-Smirnov test. The result showed that the diversity of bird species depend on the availability of feed. Bird species richness in the old-growth forest was significantly higher than the other sites. Bird diversity at wilderness zone was medium and bird diversity at rehabilitation zone was varied between low and medium.
