Use of male blue monkey "Pyow" calls for long-term individual identification

Abstract

This study examines whether individual adult male blue monkeys (Cercopithecus mitis stuhlmanni) can be identified through acoustic analysis of their "pyow" calls. It is possible to reliably assign the pyow call of the blue monkeys of Kibale Forest, Uganda, to the individual caller based on the acoustic properties of the vocalization. Analysis of pyows made by a recognizable male over a 10-yr period shows that the acoustic properties of one individual's pyow call can remain relatively constant over time. Acoustic analysis of pyow calls may provide a relatively easy and reliable method to document tenure lengths of adult male blue monkeys resident in groups. Similar analyses of the loud calls of other species of primates may, likewise, prove to be useful in documenting long-term membership. © 1992 Wiley-Liss, Inc.
