Geographic Range [top]

Range Description: Callicebus torquatus has a relatively wide range, and is the only titi monkey to be found in the Solimões-Negro interfluvium. It occurs in the state of Amazonas, on the left (north) bank of Rio Solimões/Rio Japurá, west as far as Río Apaporis/upper Río Vaupés, north delineated by Rio Negro/Rio Uaupés, east at least as far as the town of Codajás, maybe even as far as the town of Manacapurú (Hershkovitz 1990; van Roosmalen et al. 2002). A recent study (Casado et al. 2007) suggests that C. lugens may also occur south of the Rio Negro, in the municipality of Barcelos in Brazil and that the two species may be sympatric, but further surveys are needed to confirm this.

Habitat and Ecology [top]

Habitat and Ecology: No data on the ecology of this species are available. Titi monkeys (Callicebus spp.) are known to occur in a wide range of habitats, although some species exhibit habitat preferences, for example C. lucifer is reported to prefer white-sand forests (E. Heymann pers. comm. 2008), and C. donacophilus drier forests (Ferrari et al. 2000; R. Wallace pers. comm.). Members of the C. moloch and C. cupreus groups are considered tolerant of habitat disturbance caused by human activity or seasonal flooding (van Roosmalen et al. 2002).

The diet of titis comprises mainly fruit pulp, leaves, insects and seeds. They form small, pair-bonded, territorial groups and are considered monogamous. They have small home (1.5-30 km) and day ranges (0.5-1.5 km).
Systems: Terrestrial

Threats [top]

Major Threat(s): Although the species is hunted locally by indigenous people, hunting is not currently considered severe enough to be a major threat at present.
