Discovery of the great call of the Javan gibbon and finding an enclave of the agile gibbon in Kalimantan permit for the first time a comparison of vocalizations among all major taxa of Hylobates. The songs are stereotyped, constant throughout the interrupted areas of distribution of each taxon, and are sexually divocal.
