Abstract

Abstract Waterbirds are a significant part of mangrove forests due to their ecological role in the ecosystem. However, land conversion, human disturbance, pollution, and other anthropogenic factors are continued to give pressure to the existence of waterbirds, especially in the urban mangrove area. Therefore, this study aims to identify waterbirds habitat types and analyze its abundance and diversity at Lantebung Mangrove Ecotourism Area, Makassar City. Bird survey was done during three days, morning and afternoon, by walking along the peripheral of fish ponds and mudflats behind mangrove forest using binocular to identify waterbirds habitat types, kinds of species, and to count total individuals. The result shows there are four types of waterbirds habitat at Lantebung Mangrove Ecotourism Area, which are mangrove, mudflats, inactive fish ponds, and bushes. There are 18 species identified, with medium diversity (Shanon Weiner Diversity Index of 1.029), medium richness (Margalef Species Richness Index of 2.918), and stable species evenness (Hill Species Evenness Index of 0.356). Species with the highest abundance is Chadrius .sp with Relative Abundance Index 27%.
