Owl monkeys (Aotus spp.) are unique because they are the only nocturnal anthropoids. Though medical researchers have used them extensively, thorough descriptions of their social behavior are sparse. We examined in detail the social behavior of 12 male-female captive pairs of Aotus nancymaae over an entire year. We compared data from males and females to determine if there are sexual differences in scent-marking, allogrooming, and other sociosexual behavior. We compared observation periods with… 

Allogrooming in Male-Female Pairs of Captive Owl Monkeys (Aotus nancymaae)

It is concluded that allogrooming in Aotus is a normal part of their behavioral repertoire that likely serves social functions similar to those in other pair-bonded primates.

Owl Monkeys (Aotus spp.) Perform Self- and Social Anointing in Captivity

The lower back and tail were anointed at a rate significantly greater than other body parts, but there were no differences in these patterns across sex or wild- or captive-born owl monkeys.

Are olfactory traits in a pair-bonded primate under sexual selection? An evaluation of sexual dimorphism in Aotus nancymaae.

The observed sex differences and variation in olfactory traits are consistent with the hypothesis that sexual selection has influenced chemical communication in owl monkeys, with males having larger subcaudal glands and spending more time investigating odors.

Owl monkeys Aotus spp in the wild and in captivity

A truly integrated laboratory–field approach that focuses on certain areas that cannot be examined in only one or the other setting (e.g. reproductive biology, communication, energetics) will offer unique opportunities for synergistic interactions between zoo and field research that will have both intellectual and practical benefits.

Chemical composition of glandular secretions from a pair‐living monogamous primate: Sex, age, and gland differences in captive and wild owl monkeys (Aotus spp.)

The data suggest that glandular secretions of both wild and captive Aotus convey specific information, and consistent patterns across species and contexts suggest that secretions may function as chemosignals.

Effects of Olfactory Enrichment on the Stereotypic Behaviors of Owl Monkeys (Aotus nancymaae)

Olfactory enrichment elicits interest and reduces repetitive flipping in owl monkeys and may offer similar benefits to other nocturnal primates.

The potential interplay between the glandular microbiome and scent marking behavior in owl monkeys (Aotus nancymaae)

In mammals, scent marking behavior is a pervasive form of chemical communication that regulates social interactions within and between groups. Glandular microbiota consist of bacterial communities

Hormonal Monitoring of Reproductive Status in Monogamous Wild Female Owl Monkeys (Aotus azarai) of the Argentinean Chaco

It is shown that fecal samples from A. azarai can be used for monitoring female reproductive status and function, and is the first of its kind on wild female owl monkeys.

Male Reproductive Strategies in Verreaux's Sifaka (Propithecus verreauxi)

The main results of this study revealed that females residing in the same social groups come into estrous asynchronously and that dominant males may be able to monopolize each female via the use of mate-guarding, which may explain the high reproductive skew observed within the population of Verreaux s sifaka at Kirindy and why supernumerary males within social groups may be tolerated.



Sex, age, and family differences in the chemical composition of owl monkey (Aotus nancymaae) subcaudal scent secretions

Female scent profiles were greater in concentration of aromatic plant metabolites, possibly the result of a different diet or physiological differences in female metabolism as compared to male, and each family had its own unique and complex chemical profile.

Social Monogamy in the Only Nocturnal Haplorhines

The two most salient features of owl monkeys are their nocturnal habits and their monogamous social organization, and studies on the cathemeral owl monkeys of the Gran Chaco have begun to offer some insights into their social organization.

Discrimination of oestrous status in giant pandas ( Ailuropoda melanoleuca ) via chemical cues in urine

Findings indicate that female urine contains chemical cues permitting discrimination of oestrous status, and probably serves a reproductive advertisement function, and may have implications for captive-breeding programmes.

This review considers the behavioral, ecological, and reproductive characteristics of mammals exhibiting monogamy, i.e., mating exclusivity. From a discussion of the life histories of selected

The effect of social environment on estrogen excretion, scent marking, and sociosexual behavior in tamarins (Saguinus oedipus)

The social environment has a profound impact on fertility and sociosexual behavior in cotton‐top tamarin groups, with implications for callitrichid social structure and behavior.

Reproduction of the owl monkey (Aotus nancymai) (primates:Cebidae) in captivity

Breeding Aotus nancymai on a large scale in captivity is feasible and a birth peak was observed from October to January, and the mean age of a group of 12 males born in the colony when their female mates produced offspring was 42.17 ± 10.73 months.

Why do captive tufted capuchins (Cebus apella) urine wash?

The results suggest that UW does not function in thermoregulation or in territorial communication, and Qualitative evidence suggests a relationship between UW by the alpha male and sexual solicitations from females.

Social patterns of food sharing in monogamous owl monkeys

This pattern of food sharing between mates in a monogamous species may serve both nutritional and social functions that differ from those in polygamous species.

The role of scent marking in the social communication of wild golden lion tamarins, Leontopithecus rosalia

Abstract The role of scent marking in the social communication of mammals is widely variable. One reason for this variation is that the function of scent marking may vary with different ecological
