Little research has been directed towards the examination of ingestive behaviors in wild primates. This paper describes a naturalistic study of anterior tooth use in four sympatric anthropoid species: Hylobates lar, Macaca fascicularis, Pongo pygmaeus, and Presbytis thomasi. Instantaneous group scan data were collected during nearly 1,800 hours of observation between August 1990 and July 1991 at the Ketambe Research Station in the Gunung Leuser National Park, Sumatra, Indonesia. Ingestive behaviors are documented for specific food items and compared among the primate taxa. Results indicate significant differences among the species in preferred methods of food ingestion. These differences are related in part to dietary differences, and in part to other aspects of each primate's biology and ecology.
针对野生灵长类动物摄食行为的研究很少。本文描述了对四种同域类人猿物种（白掌长臂猿、食蟹猕猴、婆罗洲猩猩和托马斯叶猴）前牙使用情况的自然主义研究。1990年8月至1991年7月期间，在印度尼西亚苏门答腊岛古农列尤择国家公园的克塔姆贝研究站进行了近1800小时的观察，期间收集了即时群体扫描数据。记录了特定食物的摄食行为，并在灵长类分类群之间进行了比较。结果表明，不同物种在食物摄取的偏好方法上存在显著差异。这些差异部分与饮食差异有关，部分与每种灵长类动物生物学和生态学的其他方面有关。
