从六月到12月，收集了有关秘鲁东北亚马逊盆地的tamarin猴子的饮食和远程模式的数据。在这个7个月的时间里，昆虫和非果实水果占他培养书和觅食时间的83％。尽管降雨和森林生产力的季节性差异显着，但栖息地利用的模式，日期，饮食多样性，资源开发和活动预算在全年中仍然相对稳定。混血和鞍形的tamarins似乎可以使用相对有限的觅食模式来解决食物获取的问题，并利用贴合的喂养位点。通常，这些灵长类动物将日常喂养工作集中在来自少数目标植物物种的几棵树上。这些喂养地点很常见，每天仅产生少量的成熟果实，其特征是高度的种内结实和开花同步。同一物种的树木经常连续参观，在1-2周的时间里，单个喂养地点几次重新审视。这种类型的觅食模式发生在干燥和潮湿的季节中，以及利用水果，花蜜，豆类和渗出资源时。喂食和觅食时间的季节性变化也有限。在这项调查中，没有一致的证据表明，整体森林水果生产的时间变化对两种雌腊蛋白的饲料，觅食或范围行为都有重大影响。
From June through December, data were collected on the diet and ranging patterns of moustached (Saguinus mystax) and saddle-back (Saguinus fuscicollis) tamarin monkeys in the Amazon Basin of northeastern Peru. During this 7-month period, insects and nonleguminous fruits accounted for 83% of tamarin feeding and foraging time. Despite marked seasonal variation in rainfall and forest productivity, patterns of habitat utilization, day range, dietary diversity, resource exploitation, and activity budget remained relatively stable throughout the year. Moustached and saddle-back tamarins appear to solve problems of food acquisition and exploit patchily distributed feeding sites using a relatively limited set of foraging patterns. In general, these primates concentrate their daily feeding efforts on several trees from a small number of target plant species. These feeding sites are uncommon, produce only a small amount of ripe fruit each day, and are characterized by a high degree of intraspecific fruiting and flowering synchrony. Trees of the same species are frequently visited in succession, and individual feeding sites are revisited several times over the course of 1-2 weeks. This type of foraging pattern occurred during both dry and wet seasons and when exploiting fruit, nectar, legume, and exudate resources. Seasonal variation in the percentage of feeding and foraging time devoted to insectivory was also limited. In this investigation, there was no consistent evidence that temporal changes in overall forest fruit production had a major impact on the feeding, foraging, or ranging behavior of either tamarin species.
