Abstract

Tanjung Puting National Park (TPNP) is one of the conservation areas in Kalimantan that has important habitats for various bird species. This bird community occupies several types of ecosystems in TNTP, one of which is in the watershed. However, study about bird diversity specifically in the watersheds of Sungai Buluh Besar (SBB) and Sungai Buluh Kecil (SBK) have not yet been reported. Therefore, this study aims to determine the diversity of bird species in the SBB and SBK watersheds of TPNP. Bird species diversity were collected from 25 September to 4 October 2024 at morning (05:30 AM) to afternoon (05:00 PM) using a motorboat observation along 10 km of SBB and SBK. This observation was carried out by three observers with adequate equipments, such as aculon binoculars, nikon coolpix p1000 4k camera, and field stationery. The data collected were bird species and their abundance. Data analysis was carried out through two stages, namely determining the composition of bird species and calculating the Shannon-Wiener species diversity index (H'). Based on the results of the study, there were 57 bird species belonging to 30 families in the SBB and SBK watersheds of TPNP. The species richness in the SBK watershed (51 species) was higher than those found in the SBB watershed (43 species). Furthermore, according to Shannon-Wiener indeks (H‘), it showed that the diversity of bird species in the SBB and SBK TPNP watersheds was classified as high, with details of H’=3.32 in SBB and H'=3.38 in SBK. the individual evenness value (E=0.88) in SBB, while in SBK the individual evenness value (E=0.86), which shows a high category.
