Ateles generally lives in small temporary subgroups. The authors studied the grouping of the monkey for two months and obtained data concerning the subgroup size, composition, and inter-individual relationships. In general, the data agreed with that obtained byKlein (1972). However, they discovered that large subgroups of the monkey were observed only in relation to the utilization of a special place, the “salado” site. The authors discuss the reason for this. Criticism is given ofKlein's suggestions that the unique grouping ofAteles is a form of social adaptation to its palm-fruit eating behavior and that peripheral males exist in its social structure.
