Descrição: The examined material (207 bones and bone fragments) of 53 avian taxa from two human cave dwellings is dated between 24,000 ± 1000 BP and 9400 ± 100 BP. It reveals that 49.0% of the bird species/taxa disappeared from the recent bird fauna of the Thanh Hoa Province; 39.6% disappeared from the recent bird fauna of North Vietnam (except Thanh Hoa Province); 33.9% disappeared from the recent bird fauna of Vietnam (except North Vietnam); 28.3% are not extant in the recent bird fauna of Indochina (except Vietnam); and 52.8% disappeared from the recent bird fauna of Southeast Asia (except Indochina). This suggests more considerable influence of the Late Pleistocene climatic events on the environment and bird fauna than previously accepted in the Eastern part of the Indochinese peninsula in the last 24-millenia. The gallinaceous birds are best represented. Of the 39 Southeast-Asian species, 18 species/taxa (46.2 percent) are Galliforms. They consist of 34 percent of all bird taxa recorded in both caves. Four categories of the IUCN Red List have been represented among the established birds in the sites: LC-28, NT-7, VU-2 (Buceros bicornis and Rhyticeors undulates), and CR-2 (Lophura edwardsi and Rhinoplax vigil).
