Stone handling (SH) behavior was systematically studied in a captive troop of rhesus macaques housed at the Primate Research Institute of Kyoto University, and compared with the results of long-term studies of this behavior in Japanese macaques, to evaluate the similarities of SH behavior in these two closely related species. Similar to Japanese macaques, rhesus macaques showed age-related differences in SH. Young animals were more active and displayed more SH patterns and bouts than did adults. Furthermore, the young displayed SH at a higher frequency and their bouts were of a shorter duration, compared to adults. Young adults were more active and displayed more patterns than did older adults. On the other hand, older adults were more conservative and displayed fewer patterns, and engaged in them for longer durations. All individuals displayed SH more frequently in relaxed environmental and social conditions. While lacking an apparent immediate adaptive value, practice of the behavior has been proposed to have long-term functional value for neural and cognitive development in the young and for the maintenance or repair of neuro-pathways in aging macaques that habitually perform the behavior. The results presented here are consistent with what we know about Japanese macaque SH. Given the uniformity of SH behavioral parameters and these two macaque species' close phylogenetic relatedness, we propose that a similar functional and adaptive value for SH can be inferred for rhesus macaques.
