Vietnam is renowned for its exceptional biodiversity with birds representing the most diverse group of vertebrates in the country. Despite this richness, data on bird species composition, distribution, and populations in Vietnam remain limited, necessitating enhanced research efforts. This study addresses the research gap in Ba Ria Vung Tau (BRVT) Province, where existing studies have predominantly focused on the Binh Chau Phuoc Buu (BCPB) Nature Reserve and Con Dao National Park. Our research provides a comprehensive avian checklist and distribution data for BRVT resulting from surveys of six key ecosystems: urban areas, agricultural lands, coastal mangrove forests, tropical evergreen forests, inland freshwater bodies, and rivers and canals. Excluding BCPB and Con Dao, we conducted surveys from October 2022 to October 2023 at 52 sites using the Point Transect method. This study recorded 142 bird species, including 6 newly documented species for the province, expanding the provincial checklist to 375 species across 78 families and 21 orders. Among these, 146 species are migratory and 229 are resident. Additionally, 40 species had updated taxonomic classifications and 15 species were identified as endangered. Our findings emphasize the critical need for conservation efforts in tropical evergreen forests, inland freshwater bodies, rivers and canals, and coastal mangrove forests. Effective biodiversity management in BRVT will require increased collaboration with local communities to ensure successful conservation outcomes.
