Survey of the avifauna of Giang Man proposed nature reserve, Quang Binh province, Vietnam

Between late October and mid-November 2016, we made the first avifaunal survey in Nui Giang Man proposed nature reserve, Quang Binh province, Vietnam. Despite exceptionally adverse weather conditions, 101 avian species were recorded, several of which should now be considered threatened in Vietnam, e. g. Indochinese Wren Babbler Rimator danjoui, Wreathed Hornbill Rhyticeros undulatus and Silver-eared Mesia Leiothrix argentauris. Our survey led to a number of altitudinal range extensions, along with the first documented records of ten species for northernmost Central Annam. Our work highlights the serious gaps in the basic avifaunal understanding of the northern Annamite avifauna as well as the requirement for additional basic field inventories across this under-sampled region.
