摘要:
Field recordings of male loud calls (or roars) from each major form of black-and-white colobus monkey have been analyzed spectrographically, and features of tempo and pitch measured. Considered together with data on cranial dimensions, coat pattern, and geographical distribution, the results of this analysis suggest that there are five species of black-and-white colobus: Colobus angolensis, C. guereza, C. polykomos, C. satanas, and C. vellerosus. C. guereza and C. vellerosus may have differentiated most recently during a major arid event prior to the last Pleistocene glacial maximum; they have an identical low-pitched roar which we consider to be a shared, derived character. The other species, of which C. satanas has the most distinct roar, may belong to older lineages.
