Vocalizations Reveal Species Differences in Endangered Lion Tamarins (Primates, Callitrichidae).

ABSTRACT: Acoustic communication is important for social cohesion and territory defense in forest primates, including the endangered lion tamarins (genus Leontopithecus). Although vocalizations of individual species have been studied, there is still no comparative analysis examining whether acoustic parameters can reliably distinguish among all four species. We hypothesized that species-specific differences in acoustic features allow discrimination among lion tamarin species, and we predicted that both spectral and temporal parameters would reveal interspecific variation. To test this, we analyzed seven shared vocalizations (long calls, whines, trills, rasps, clucks, tsicks, and peeps) from the black-faced lion tamarin (Leontopithecus caissara), golden lion tamarin (Leontopithecus rosalia), golden-h
