Juvenile and adult females in two wild groups of wedge‐capped capuchin monkeys (Cebus olivaceus) were observed nursing from other adult females. The context of the interactions varied with participants but always involved a higher‐ranking female nursing from a lower‐ranking female. This behavior appears to be an example of an exploitative interaction in which the suckling female benefits at the expense of the nursing female. 

Allonursing in white-faced capuchins (Cebus capucinus) provides evidence for cooperative care of infants

It is concluded that infant white-faced capuchins engage in allonursing as a means to acquire additional milk, and that participating allonurses may benefit from increased inclusive fitness.

Female‐female social relationships in wild white‐faced capuchin monkeys, Cebus capucinus

The patterning of social interactions indicates that Cebus capucinus at Lomas Barbudal are female bonded, and females could be ranked in a stable, linear dominance hierarchy.

Equal care for own versus adopted infant in tufted capuchins (Sapajus spp.)

A case of adoption by a female tufted capuchin who spontaneously adopted a newborn immediately after he was abandoned, then raised him successfully with her own infant, showing no difference in the active care of the adoptive mother.

Twinning in Tufted Capuchins (Cebus apella): Rate, Survivorship, and Weight Gain

The finding that at no time during the first year of life do twins and singletons differ significantly in their weights, suggests that twinning is a viable reproductive form for these animals, especially in the captive setting where nutritional demands are met.

Cooperative breeding in reindeer (Rangifer tarandus): testing the hypothesized causes of allosuckling and allonursing.

The results of this thesis demonstrate that the direct fitness benefits of milk-theft, reciprocal allonursing and improved nutrition and mass gain maintain all onursing in reindeer, and suggest that the indirect Fitness benefits of alloparental care may have been overestimated.

Critical Issues in Cebine Evolution and Behavior

It is argued that in the past 20 years, new molecular, genetic, morphological and behavioral analyses have narrowed the range of possible explanations regarding Cebus and Saimiri, in particular.

Social parasitism in mammals with particular reference to neotropical primates

It is shown that not only do animals but also humans respond in ways that appear to benefit others rather than themselves, which is consistent with the views of Darwin and Dawk.



Seasonal variation in use of time and space by the wedge-capped capuchin monkey, Cebus olivaceus : implications for foraging theory

The relationship between the foraging behavior of a group of wedge-capped capuchin monkeys Cebus olivaceus and the abundance and spatial distribution of resources, was examined in a highly seasonal gallery forest in central Venezuela during 14 months to evaluate the behavioral mechanisms regulating group foraging.

Alloparental care and adoption of young, aparently altruistic and reproductively costly behaviors, have been reported in over 120 mammalian and 150 avian species. Members of these taxonomically and

Altruism Among Female Macaca Radiata: Explanations and Analysis of Patterns of Grooming and Coalition Formation

Analysis of the observed patterns of two forms of putative altruism among adult female members of a group of captive bonnet macaques (Macaca radiata) indicates that both kinship and dominance rank influence the distribution and rate of these behaviors.
