Abstract The vocal structure of gibbons has long been believed to be under strong genetic control and consistent with phylogeny. Gibbon vocalizations show hierarchical structures song coordination behaviors, which may have different functions convey distinct information compared basic notes. However, previous studies not at multiple levels across species. We the three Nomascus species in wild South China, namely western black gibbon ( concolor ), Cao vit N. nasutus Hainan hainanus ) note (six features four types notes), male sequence (eight features), (four overlap pattern between female songs). selected 15 recordings for each species: groups, 2006 2021), (seven 2008 2020 2021). used permuted random forest analysis test differences contribution acoustic level. construct a clustering tree, it phylogenetic relationships. found significant all except boom note. Acoustic similarity did match pre-modulated notes, suggesting that are only factor leading structures. also contributions differentiation levels. Our study suggests we need compare understand their evolution.
