The social organizations of squirrel monkeys: Implications for ecological models of social evolution
TLDR
“Squirrel‐monkeys occur in a considerable number of slightly different forms, but all are built upon a similar body plan and have a basic color scheme, and some of these pure color variations may constitute valid regional subspecies or even species.
Habitat use by squirrel monkeys (Saimiri oerstedi) in Costa Rica.

TLDR
In all seasons dispersion was least when the troop was travelling and it was generally greatest during seasons of low food abundance, and measures of the allocation of time by the troop to food-related activities and the extent of troop dispersion each season were consistent with estimates based on behavior sampling of individuals.
Competitive regimes and female bonding in two species of squirrel monkeys (Saimiri oerstedi and S. sciureus)
TLDR
The correlated ecological and social variables found in these two congeners further minimize the minor effects of phylogenetic differences and emphasize the importance of food distribution in determining social characteristics.
Morphological and behavioral adaptations for foraging in generalist primates: the case of the cebines.
TLDR
The conclusions include the following: first, body size is extremely important in explaining the observed variation in diet, and the emphasis on faunivory is facilitated more by behavioral than by morphological specialization.
AN EXPANDED TEST OF THE ECOLOGICAL MODEL OF PRIMATE SOCIAL EVOLUTION: COMPETITIVE REGIMES AND FEMALE BONDING IN THREE SPECIES OF SQUIRREL MONKEYS (SAIMIRI OERSTEDII, S. BOLIVIENSIS, AND S. SCIUREUS)
TLDR
Similar ecological and behavioral data from long-term field observations of known individuals of S. sciureus are used to expand the test of ecological models to three species, finding that in all three sites female within-group direct competition regimes clearly follow from the distribution of fruit patches.

SummaryThe mating system of squirrel monkeys (Saimiri oerstedi) in Parque Nacional Corcovado, Costa Rica was studied and used to develop a model to interpret the evolution of seasonal sexual
Disparate Data Sets Resolve Squirrel Monkey (Saimiri) Taxonomy: Implications for Behavioral Ecology and Biomedical Usage
TLDR
A strongly supported squirrel monkey phylogeny is reported, congruent across multiple data sets, including new field data and the first molecular (mtDNA) cladogram, which support species-level classification for the three major groups in this study.
Use of a club by a wild white‐faced capuchin (Cebus capucinus) to attack a venomous snake (Bothrops asper)

In Parque Nacional Manuel Antonio, Costa Rica, an adult male Cebus capucinus was observed repeatedly hitting a venomous snake (Bothropsasper) with a branch. Initially a large dead branch overhanging
Sex differences in the foraging behavior of squirrel monkeys in a seasonal habitat

  • 1 September 1988
TLDR
There was little evidence of any direct foraging benefits for a squirrel monkey from being social, but females searched for and ate food at significantly greater frequencies than did males throughout the study.
Patterns of individual diet choice and efficiency of foraging in wedge-capped capuchin monkeys (Cebus olivaceus).
TLDR
Within-group variability in foraging reflected catholic selection and equivalent treatment of substrates by all individuals, rather than individual specializations.
