Abstract. Andrimida A, Sonhaji A, Hardiyan FZ. 2024. Diversity of waterbirds around Ekasoghi mangrove area, Sumenep, with the first record of Australian tern (Gelochelidon macrotarsa) from Madura Island, Indonesia. Indo Pac J Ocean Life 8: 10-17. Mangrove forests provide an essential habitat for a lot of organisms, and they also provide an important habitat for waterbirds. This study aims to provide an overview of waterbirds' diversity and abundance around Ekasoghi mangrove area situated on the eastern coast of Sumenep, Madura Island on East Java, Indonesia. This research was conducted at three stations, each representing a different habitat type around Ekasoghi mangrove area. Waterbird data was collected using the exploration method, and waterbird species were determined by examining their morphological characteristics. Waterbirds' diversity was determined using the Shannon-Wiener diversity index, and the abundance was determined using the abundance index. Moreover, 38 individuals belonging to 15 species from 4 orders and 6 families were recorded during this study, with more than half belonging to the Charadriiformes order; the waterbird diversity index ranged from the highest 1.97 to the lowest 1.33. Three species with the highest abundance index value are striated heron (Butorides striata) with an abundance index value of 18.42, followed by Javan plover (Anarhynchus javanicus) and common sandpiper (Actitis hypoleucos) as the second with an abundance index value of 13.16. This research also provides the first record of the migrating seabird Australian tern (Gelochelidon macrotarsa) from Madura Island.
