Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Marsh, L.K. & Veiga, L.M.
Reviewer(s): Mittermeier, R.A. & Rylands, A.B. (Primate Red List Authority)
Listed as Least Concern as although the distribution of this species is not well known, it appears to be relatively widely distributed south of the Napo in lowland Ecuador and Peru, and there is no reason to believe that it is currently undergoing a decline that would warrant listing in a higher category of threat.

Habitat and Ecology [top]

Habitat and Ecology:P. aequatorialis occurs in moist subtropical lowland forest.

Sakis are medium-sized primates (1-3 kg). They are specialized morphologically for seed predation. The diet is made up of seeds, fruit pulp, young leaves, insects and flowers. Members of this genus form small, cohesive groups (2-9 individuals), generally comprising a single male-female breeding pair and several young. Day ranges (1,5-2 km) and home ranges are small (10-25 km), and sakis exhibit behaviours associated with territory defence (Norconk 2007).

Threats [top]

Major Threat(s): In Peru, the main threat is hunting and habitat loss (Aquino and Encarnación 1994). They are sometimes found in the pet trade.

Conservation Actions [top]

Conservation Actions: This species is not present in any protected areas in Peru (Aquino and Encarnación 1994).
It is listed on CITES Appendix II.
