title: Birth timing and social rank of adult male rhesus monkeys (Macaca mulatta).
abstract: The distribution of birth dates of offspring of high-ranking adult males was compared with that of offspring of low-ranking adult males. A significantly greater number of the offspring of high-ranking males were born earlier during the birth season than were those of low-ranking males (chi 2(2) = 10.00, p less than 0.01). Higher reproductive success might be maintained by adult rhesus monkeys of high rank not only by the intensity but also by the timing of their mating activity.
