Kuchinoerabu-jima is extremely valuable in terms of biodiversity conservation. However, little is known about its avifauna compared to surrounding islands. In particular, there is no information on the summer avifauna in this island. We first surveyed bird assemblage of Kuchinoerabu-jima in the summer of 2022 and detected 15 species, including 3 endangered and 6 newly recorded species. 60% of the species identified were resident birds, but some of the newly recorded species were migratory birds staying for the summer or resting on the way to their final destination. Thus, our study provided basic information needed when considering the ecosystem conservation of Kuchinoerabu-jima.
