“…In addition, the role of infants in attracting the attention of females and initiating the process of adoption was experimentally demonstrated in captive hanuman langurs (DoLHINOW, 1980;DOLHINOW,~r DEMAY, 1982) and also observed in the wild mantled howler monkeys (CLARKE & GLANDER, 1981). Unsuccessful adoption of infants have been reported in chacma baboon (HAMILTON et al, 1982), yellow baboon (RHINE et al, 1980), and Japanese macaque (HASEGAWA ~r HIRAIWA, 1980). However, since the adopter was non-lactating female the adoptee was unable to survive for more than two days.…”

This report describes three cases of infant adoption in red howler monkeys (Alouatta seniculus) of Venezuela. In one case, a lactating female adopted her infant granddaughter after the infant's mother disappeared and the infant survived for the next 25 months. In the second case, an adult female adopted her infant granddaughter for nine days while the infant's mother was still a group member. In the third case, a nulliparous female temporarily adopted an infant from a neighboring group. The details and the possible reasons for these adoption are described.

“…Five infant rhesus macaques who were forcibly separated from their social groups showed protest and mildly depressive responses, as indicated by decreases in locomotion, vocalization, exploration, and feeding. Studies of permanently orphaned infants in the field have described depressed behavior usually followed by death, particularly for orphans who were not adopted by group companions (Berman, 1982;Hasegawa & Hiraiwa, 1980;Rhine, Norton, Roertgen, & Klein, 1980). Worlein, Eaton, Johnson, and Glick (1988) found increased frequencies of matemal rejections and infant distress among corral-housed Japanese macaques during the mating season.…”

Responses of Free-ranging Rhesus Monkeys to a Natural Form of Social Separation. I. Parallels with Mother-Infant Separation in Captivity

Observations of 23 free-ranging rhesus monkey infants on Cayo Santiago, Puerto Rico, indicated that mothers' first postpartum estrous periods were marked by large increases in the amount of time infants were separated from their mothers, by disturbances in mother-infant relationships, and by increases in infant distress behavior. When their mothers resumed mating, most infants showed signs of agitation; a few briefly showed indications of depression. Male infants responded to their mothers' resumption of mating by playing more, whereas females engaged in less play and more allogrooming. The results suggest (a) that basic parallels exist between the behavioral responses of rhesus infants to their mothers' resumption of mating in the field and to forcible separation from their mothers in captivity and (b) that early separation experiences may play a role in the normal development or manifestation of sex differences in behavior.

The habitat and plant feeding of 64 well-habituated, individually identified adult male and female yellow baboons was studied for 5 years at Mikumi National Park, Tanzania. Variation across the years showed that a study of only one or two years would have been incomplete and misleading. The list of baboon food species obtained from Mikumi is considerably larger and more diverse than any previously reported. One to six plant parts were eaten from each of more than 180 species. The 25 most common tree genera all contained species used for food. Of the 50 most common grass, shrub and herb genera, 93% included plant foods. Using months in which a species was eaten during at least one year of the study, 21 staple species were eaten during a mean of 8.86 months and 7 were eaten in all 12 months. Although many foods were from commonly available plant species, 15 such species were only rarely eaten. The number of parts of a species eaten per month and an estimate of the amounts eaten per month both varied with temperature and rainfall, being lowest near the end of the cool, dry season. There were substantial differences from year to year in the timing and amount of food production of many species; nevertheless, the same broad feeding pattern was repeated in each of the 5 years of the study. Despite yearly variation in food availability, 14 or more staples and other common foods were eaten in any given month. If crops of many of these foods were to fail, a large number of less commonly eaten species could be substituted. Baboons are eclectic feeders that appear to be optimizing their diet by selective feeding from among a wide array of available foods in an ever-changing floristic environment.
