Abstract: Among four rhesus monkey populations, comparing in ascream indicates that there is no significant difference in the subsequent behaviors of screamer. In spectrum characters of the scream , there are no significant differences, among individuals and among the free geographic populations of Hunan’s Suoxiyu, Guangxi’s Longhushan and Hainan’s Nanwan. But, between the above three populations and Shenzhen’s Neilingding population, the difference in the scream’s spectrum characters is significant. The result from discriminant analysis, reveals that the fundamental frequency (F1) of screams is important to interpopulation discriminating. 　　For the different populations, the tendency to increased audible range and signal specialization in rhesus’s scream , is related to the lighter rainfall of habitat and larger groupsize. In fact, it is essential, that the tendencies relating to rainfall and group size in rhesus’s scream are the adaptations to mainland, island and tropic area.
