Abstract

Primates show great diversity in their social organisation. Rwenzori black-and-white colobus (Colobus angolensis ruwenzotii) are intriguing for forming a supergroup of several hundred individuals in Rwanda, but it is unknown how these societies are organised. I observed the supergroup over 13 months in 2016/17, aiming to describe the supergroup's 'anatomy'. My results suggest that the colobus form a multilevel society composed of multi-male, multi-female units and one-male, multi-female units that are embedded in a larger band. Limited competition over mature foliage and a reliance on lichen as a fallback food during lean times facilitate the formation of a large band.
