“…This is especially interesting when his later history is considered. R006 became the dominant male in group F late in 1963 [Sade, 1966] and continued in that status until late 1967 [Loy, 1971].…”

“…3). Their estrous dura tionwas considerably longer than any of those reported so far (13.6 days [Takahata, 1980] or 8.9 days [Huffman, 1991] among Japanese macaque females in a provi sionedtroop; 9.2 days [Carpenter, 1942], 11.0 days [Kaufmann, 1965], or 5.2 days [Loy, 1971] among rhesus macaque females of Cayo Santiago). They showed es troussigns throughout the menstrual cycle, in "runs" as reported in a provisioned troop of Japanese macaques (Wolfe, 1984).…”

“…Females in some macaque species are sexually active both midcycle and perimenstrually (Loy, 1970), and often show prolonged estrus (Takahata, 1980). They also show frequent postconception estrus (e.g., Japanese macaque; Hanby et al, 1971;Takahata, 1980: Rhesus macaque;Loy, 1971: Barbary macaque; Kuster and Paul, 1984), which is not directly related with reproduction. Hanby et al (1971) pointed out that receptivity and attractivity of Japanese macaque females who conceived were not different from those who had not conceived, and that neither ovulation nor conception had any discernible effect on the frequency and pattern of sexual activity, nor were female dominance and age related to early conception.…”

Contrast of Estrus in Accordance with Social Contexts Between Two Troops of Wild Japanese Macaques on Yakushima.

I observed estrus in two adjacent troops (A-troop and M-troop) of wild Yakushima macaques during the 1984 mating season. A-troop females showed short and regularly cycling estrus periods, seldom came into estrus simultaneously, and scarcely failed to mate when they were in estrus. In contrast, females of M-troop, which went through troop takeovers during the mating season, demonstrated mate competition and subsequent estrus prolongation. Early in the mating season, con stantlyfour to seven females of M-troop were in estrus simultaneously, competed for troop males (TMs), and some of them failed to mate. Subsequently many non -troop males (NTMs) approached to the troop, estrous females mated with them frequently, and mating harassments by females decreased. Among those NTMs, one dominated all TMs, which was referred to as a troop takeover. Successively three other NTMs dominated both all TMs and the former dominant NTM, and in total, four troop takeovers occurred in M-troop during this mating season. The fe malescontinued to be in estrus during the whole episodes. All the conceived fe malesalso showed prolonged postconception estrus, and they were neither inactive nor less attractive to males. It was suggested that M-troop females increased their opportunity to mate with NTMs by estrus prolongation, at the cost of female-female mate competition, to incite active male intertroop movement and subsequent troop takeovers.

“…However, CN also gave more care to young than any o f the female caretakers. During the mating seasons, CN's sexual behavior appears to be like that of any normal male [Loy, 1971]. CN is, how ever, the oldest male in group F. Older males tend to give more care to young than other age groups of males ( fig.…”

“…While it is true that a mother may spend a great deal of time grooming her offspring, she may also spend a comparable amount of time grooming her own mother, her mother's sister(s), any or all of their offspring, and even her grandmother [Sade, 1965]. During her estrous periods, which may persist during the non mating season [Loy, 1969], she will spend a good deal of time grooming a male or males. Also she grooms her 'friends': other adult females with whom she interacts frequently.…”

The purpose of this paper is to describe and explore the significance of parental activities among Macaca mulatta. The phylogeny of care-giving behavior and the terminology that has been used in reference to it are discussed briefly.The focus of the paper is the presentation of original data from a continuous 15-month study of a free-ranging social group of rhesus monkeys in which the birth date and the mother of most individuals were known. Care giving was ubiquitous in the social group. Sex differences were minimal and, for the most part, quantitative rather than qualitative.
