Abstract
A 150-member troop of Japanese monkeys (Macaca fuscata)was translocated from its temperate native habitat, near Kyoto, Japan, to a 42-ha enclosure near Laredo, Texas, in February 1972. The seasonal timing and distribution of 430 births recorded over the period 1954–1971 were compared to those of 186 births recorded in Texas from 1973 to 1979. Despite striking climatological and environmental differences between the pre- and the postranslocation sites, the timing of the birth season remaines unchanged, although the distribution of births was altered. These findings, considered in light of other published data on the seasonality of mating in macaques, suggest that a phenomenon akin to social drift may account for much of the intertroop variation that occurs.
