Pulau Bintan is the largest island in the Riau Archipelago, Indonesia. During two brief visits in 2018, a total of eight species new to the island were recorded, increasing the island’s bird checklist to 189 species. These new records are Grey Heron Ardea cinerea, Intermediate Egret Ardea intermedia, Red-wattled Lapwing Vanellus indicus, Horsfield's Bronze-cuckoo Chalcites basalis, Tiger Shrike Lanius tigrinus, White-headed Munia Lonchura maja, Sooty-headed Bulbul Pycnonotus aurigaster and Javan Myna Acridotheres javanicus. Three of our new records appear to be new for the Riau Archipelago, increasing the avifaunal checklist for the archipelago to 232 species. Following years of development, little primary vegetation remains on Bintan Island, and our failure to detect any woodpeckers by sight or sound during our visits is worrying in terms of the importance of these birds to ecosystem sustainability. Nonetheless, the island retains sizeable area of natural forests, including some swamp forest patches, and our new and significant records suggest its avifaunal diversity is still understudied and underestimated. We call for relevant Indonesian government agencies and the Bintan Resorts, which manage the northern portion of the island for tourism development, to strengthen efforts in biodiversity research and conservation, as well as habitat restoration, so as to attain the development goal of making Bintan a true “eco-island” for international tourism.
