Sakis, uakaris, and titi monkeys: behavioral diversity I a radiation of primate seed predators. Primates in perspective. Brown-bearded sakis spend to minutes a day feeding, not including travel time between food resources. While foraging they split up into smaller feeding units of around nine individuals and move rapidly in a cohesive manner between groups of feeding trees.

Once the troop has arrived at a new feeding area they then split up, staying within a radius of 50 to 75 m, well within range of each others vocalizations which they keep up constantly. The pattern of rapidly moving between food trees with periods of relatively short but intense feeding bouts observed in brown-bearded sakis is to be expected of a specialized species concentrating on widely dispersed, seasonal, high protein food sources. Brown-bearded sakis avoid predation largely through occupying the highest levels of the forest canopy and through their large body size.

Quadrupedal leaping is also a helpful predator avoidance mechanism allowing a speedy and difficult to follow getaway. Harpy eagles, jaguars, and humans are the primary predators of Chiropotes satanas. As frugivores, brown-bearded sakis play a role in distributing seeds of fruiting trees.

Their role as seed dispersers, however, is decreased by the fact that they eat immature seeds of unripe fruits. Their ability to get at immature seeds in unripe fruits also effects sympatric frugivorous species like Ateles paniscus and Cebus apella who eat some of the same fruits, but only when ripe.

Brown-bearded sakis often live sympatrically with several other Platyrrhini species such as Alouatta seniculus , Saimiri sciureus , Saguinus midas , and Pithecia pithecia. Fleagle and Meldrum, ; Fleagle, ; Van Roosmalen, et al. Some groups of humans benefit from Chiropotes satanas by hunting them for meat and body parts. Humans also may benefit economically from keeping some black-bearded sakis in zoos. There are no known adverse effects of Chiropotes satanas on humans. Chiropotes satanas is considered endangered because of human induced habit degradation and hunting.

The formation of protected areas may be improving the prospects for populations of Chiropotes satanas chiropotes. In birds, naked and helpless after hatching. Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. Synapomorphy of the Bilateria. Ecotourism implies that there are existing programs that profit from the appreciation of natural areas or animals.

Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a now extinct synapsid ancestor; the fossil record does not distinguish these possibilities. Convergent in birds. Iteroparous animals must, by definition, survive over multiple seasons or periodic condition changes. Epiphytes and climbing plants are also abundant. Precipitation is typically not limiting, but may be somewhat seasonal.
