Mainly tall terra firma forest but also seasonally flooded forest, forest fragments, and transitional, savanna-like forest. Red-nosed Bearded Sakis prefer the middle and upper layers of the forest canopy. They tend to be restricted to undisturbed habitats. Permanency in forest fragments smaller than 100 ha is possible by a combination of crucial ecological factors, such as presence of key resources and absent or reduced hunting pressure.

The Red-nosed Bearded Sakiis highly frugivorous, with a specialization for seeds. Fruits and parts offruits account for as much as 90% of the diet. J. M. Ayres carried out the first field study on Red-nosed Bearded Sakis in Aripuana, Mato Grosso. Individuals were difficult to habituate due to intense hunting, so four different groups were followed for no more than 4 hours/day. Diets of different groups consisted of mature fruit (54%), immature seeds (36%), and flowers (3%), along with small amounts of petioles, leaves, and bark. Immature seeds were consumed more often in the dry season. Ayres recorded 51 plant species from 20 families in the diet (n = 128 feeding bouts). The top five most exploited plant species were

Immature seeds were consumed most often (48%), followed by ripe fruit pulp (39%), mature seeds (6%), flowers (5%), and small quantities of immature pulp, invertebrates, and other dietary items. The study group fed on 125 plant species from 38 families (n = 5197 feeding records).

Ayres suggested that groups of Red-nosed Bearded Sakis were made up of unimale subgroups, but the mating system is not yet well understood. Copulation takes place on large horizontal branches and lasts 20-50 seconds. Average gestation in captivity is ¢.150 days, and the nursing period is ¢.3 months. In Aripuana, there were two birth peaks: February (wet season) and August-September (dry season). At Tapajos, mating and births occurred throughout the year.

Red-nosed Bearded Sakis are diurnal and arboreal. In Tapajos National Forest, groups usually wake before dawn and retire to sleeping sites at or after dusk, being active, on average, for twelve hours and 20 minutes each day. Groups chose tall trees to sleep in, changing sleeping sites each night. Most of the timeis spent traveling (36%), followed by diurnal resting (27%), and feeding (24%). About 13% of the day is spent playing, vocalizing, grooming, and engaging in other social activities. Time spent traveling is correlated positively with daily average group size.

Red-nosed Bearded Sakis live in multimale-multifemale groups of up to 56 individuals, showing a fission-fusion dynamic in which group members split into subgroups of different sizes. At Aripuana, groups had 19-26 individuals that were never separated by more than a few meters. Red-nosed Bearded Sakis there associated with other primates 29% of the time, including Guianan Brown Capuchins (Sapajus apella), Humboldt's Woolly Monkeys (

marginatus). These associations lasted a few minutes to more than a day. Daily movement in Tapajos was 1840-7809 m (average 3667 m). At Aripuana, daily movements were 2500-5000 m, and daily distances traveled were greater in the dry season when ripe fruit was scarce. Home ranges in Aripuana were 200-350 ha, whereas in Tapajos, they exceeded 1000 ha—the largest home range recorded for the genus and one of the largest recorded for a Neotropical primate. Population surveys have provided sighting rates of 0-06 groups/10 km on the Santarém-Cuiaba Highway to 1-8 groups/10 km in Amazonia National Park.

CITES Appendix I. Classified as Endangered on The [UCN Red List. The endangered status of the Red-nosed Bearded Sakis is due to a projected decline of at least 50% during the next 30 years. Major reasons for the projected decline are the expanding agricultural frontier in its distribution, and hunting. Red-nosed Bearded Sakis are hunted for food and occasionally for their tail (used as dusters). A large part of the distribution of the Red-nosed Bearded Saki has been deforested or fragmented by logging, cattle ranching, and agricultural monocultures. Paving of the Trans-Amazon and Santarém-Cuiaba highways has accelerated the rate of degradation and forest loss by facilitating access to previously remote areas. Other infrastructure projects planned or underway are hydroelectric reservoirs on the rios Teles Pires,Juruena, Tapajos,Jamanxim, and Madeira, which also contribute to habitat loss and an increase in human populations. Red-nosed Bearded Sakis occur in Amazonia and Jamanxim national parks and Tapajos, Crepori, Trairao, Itaituba I, Itaituba II, and Jamanxim national forests.
