Abstract

Small islands are extremely vulnerable to ecosystem disturbances. One of the common factors impacting on island ecosystems is the rise of tourism activity and the associated conversion of mangrove forest’s function into tourism’s supporting facility. Those changes will ultimately affect the diversity of bird species inhabiting the island. Therefore, this study aimed to analyse the structure of a bird community in the mangrove forests of the Pahawang Island. The study used the transect method with tracking implemented. The obtained data were analysed using the Shannon-Wienner diversity index. We recorded 28 species from 21 families. Out of 21 families, Columbidae had the highest number of species (three species). Seven feeding guilds were observed during the present study, the maximum number of species belonged to the insectivore group and the minimum – to the nectarivore and omnivore (1 species each) guilds. Based on the abundance rank, the most abundant species was the cave swiftlet (Collochalia linchi). Three of the recorded species are listed in the category “Protected” according to the Indonesia Law: the brahminy kite (Haliastur indus), sunda pied fantail (Rhipidura javanica), and the black-naped tern (Sterna sumatrana). All bird species that have been recorded during the present study is classified as “Least Concern” in the IUCN Red List. The values of the Shannon-Wienner index suggest neither high nor low diversity (H’ = 2.55). Mangrove forest ecosystems, including the mudflat on the Pahawang Island, are important supporting populations of wild birds through providing foraging, roosting and nesting sites.
