在以嵌入木质基质中的昆虫为食的物种中，这些动物用来确定在何处寻找嵌入的无脊椎动物的感觉cucs尚不清楚。虽然这些搜索可以是随机的，但是可能采用诸如听觉、视觉和/或听觉线索的感官线索。Erickson及其同事进行的研究表明，指猴（Daubenmnia madagascarien-3175）使用敲击扫描通过声音线索收集有关嵌入木材中的无脊椎动物位置的信息[Erickson，1991，1994; Erickson等人，1998年]。我们提供了一个初步的报告，在这里使用的自来水扫描棕色卷尾猴（Cebus猿/LA），这表明参与的声音线索在提取foraging.Capuchins是机会主义的食果动物，消费各种各样的植物和动物的食物。适应，包括一个对生拇指，在C。驱逐/a，强壮的下颚，使这种广泛的食物开发成为可能。它们的饮食中有60%到80%是水果，20%到40%是昆虫、鸟蛋，
1n species that forage upon insects embedded in woody substrates, the sensory cucs used by these animals in determining where to search for embedded inverte—brates are unclear. While these searches may be random, sensory cues such as 01—faetory, visual and/or acoustic cues are likely to be employed. Studies conducted by Erickson and his colleagues indicate that aye—ayes (Daubenmnia madagascarien—3175) use tap—scanning to gather information through acoustical cues about the loca—tions of invertebrates embedded in wood [Erickson, 1991, 1994; Erickson et al., 1998]. We provide a preliminary report here on the use of tap—scanning by brown capuchin monkeys (Cebus ape/la), suggesting the involvement of acoustic cues during extractive foraging.Capuchins are opportunistic frugivores, consuming a wide variety of plant and animal foods. Adaptations, including an opposable thumb and, in the case of C. expel/a, robust mandibles, make this wide exploitation of foods possible. Between 60 and 80% of their diet consist of fruits and 20—40% consists of insects, bird eggs,
