 | | Although white-faced sakis are well represented in zoos, they remain one of the least understood of the South American primates, primarily because so few studies have examined them (Vecchio and Miller, 1993). |
 | | Because of their accessibility to us (we have one of the largest collections of white-faced sakis in the U.S.), and the advantage of using them as a research model to better understand endangered members of the subfamily Pitheciinae (Chiropotes and Cacajao), we began the first long-term studies on the reproductive biology of this species. |
 | | The objectives of this research is to document the reproductive cycle in captive white-faced sakis by means of urinary and fecal steroid metabolite measurements; to examine the parental care patterns and development of infants; to describe species typical behavior; and to determine the mating system of these animals in captivity (Savage et al., in press). |
