Data on the ecology and diet of buffy sakis (Pithecia albicans) were obtained during a 20-month study in an entirely undisturbed terra firme forest in the upper Urucu river, Amazonas, Brazil. Groups of 3-7 sakis found in a 900-ha study plot used large home ranges (147-204 ha), which overlapped extensively with those of neighboring groups. Similar to other pitheciines, buffy sakis were primarily seed predators, relying heavily on young seeds of certain key plant families, such as the Sapotaceae and Leguminosae. Ripe fruits, ripe seeds, young leaves, flowers, and nectar were eaten to a lesser extent. Whether or not feeding, sakis spent most of their time in the canopy and subcanopy, a pattern similar to that of other southwestern Amazonian saki species, but sharply different from that of Guianan sakis (Pithecia pithecia), which use considerably lower levels of the forest. Comparisons are made between different Pithecia species to show whether and how P. albicans diverges ecologically from its congeners. © 1993 Wiley-Liss, Inc.
关于黄褐伶猴（Pithecia albicans）的生态和饮食数据，是在巴西亚马孙州乌鲁库河上游一片完全未受干扰的高地森林中进行的为期20个月的研究期间获得的。在一个900公顷的研究区域内发现的由3至7只伶猴组成的群体，使用面积很大的活动范围（147 - 204公顷），这些活动范围与相邻群体的活动范围广泛重叠。与其他伶猴科动物相似，黄褐伶猴主要以种子为食，严重依赖某些关键植物科的嫩种子，如山榄科和豆科。成熟果实、成熟种子、嫩叶、花朵和花蜜的摄入量较少。无论是否进食，伶猴大部分时间都在树冠层和亚树冠层活动，这一模式与其他亚马孙西南部伶猴物种相似，但与圭亚那伶猴（Pithecia pithecia）截然不同，后者利用的是森林中低得多的层次。对不同伶猴物种进行了比较，以表明黄褐伶猴在生态上是否以及如何与其同属物种有所不同。© 1993威利 - 利斯公司。
