  author={Orrey P. Young},
On Barro Colorado Island, Panama, a solitary male howler monkey (Alouatta palliata) was observed copulating with a female member of a troop. A unique tree-rubbing behavior was then performed by the male. Within two weeks he was the dominant male in that troop. 

Lone males: Solitary and group-living male howler monkey (Alouatta palliata) behavioral ecology in a Costa Rican rainforest.

The results demonstrate that lone males differ in their behavioral ecology compared to group-living males, thus improving understanding of the solitary male life stage in primates.

Contexts of rubbing behavior in Alouatta guariba clamitans: a scent‐marking role?

Three wild groups of Southern brown howler monkeys, Alouatta guariba clamitans, were studied at Morro Geisler, Indaial, Brazil, from September 2004 to February 2005; data on performers and associated contexts showed that anogenital, dorsum and hyoid regions were the most often rubbed.

A sternal gland in the Siamang Gibbon(Hylobates syndactylus)

The sternal gland of the siamang gibbon may be derived from a marking gland which specialized secondarily to serve parallel functions like those served by the axillary organs of humans and the African apes.

Searching for Alouatta palliata in Northern Colombia: Considerations for the Species Detection, Monitoring and Conservation in the Dry Forests of Bolívar, Colombia

Abstract The conservation status of A. palliata, commonly referred to as black mantled howler monkey, is vulnerable in Colombia because of its decline in population. The distributional limit in the

Anointing variation across wild capuchin populations: a review of material preferences, bout frequency and anointing sociality in Cebus and Sapajus

Previously unpublished data on anointing behaviors from capuchin monkey populations at ten different field sites are presented and reviewed, finding evidence that wild Cebus anoints at a significantly higher frequency than Sapajus in the wild, but contrary to the captive literature, there is no difference in the range of sociality for anointeding between Cebus and Sapaju in theWild.

This review concludes that a prisoner’s dilemma model of the evolution of paternal care in a multi-male primate society is a viable option and should be considered.
