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.
发现爪哇吼猴的叫声和在加里曼丹发现敏捷吼猴的聚居地,使得首次能够对所有主要的合趾猴类进行声音比较。这些歌声是刻板不变的,在每个分类群的分布间断区域都是如此,并且具有性二态性。
