The diet of the white-lipped peccari Tayassu pecari was studied from July 1996 to April 1997 in Corcovado National Park, Costa Rica, through fecal analysis and direct observations. The feces consisted of 61.6% fruits, 37.5% vegetative parts, 0.4% invertebrates and 0.5% unidentified material. These proportions are similar to those reported for white-lipped peccaries diet in South America, but the species consumed were different. In Corcovado, the white-lipped peccary fed on parts of 57 plant species (37 of them fruits). Moraceae was the most represented family. In contrast, the diet of the Peruvian Amazon peccary primarily consists of plant parts (Arecaceae). Costa Rican peccary diet consisted of vegetative parts from Araceae and Heliconaceae. Direct observation showed that peccaries spent 30% of feeding time rooting. Samples taken from rooting sites suggest that peccaries fed on earthworms. Diet differed between months, seasons and habitats. They ate more fruits in coastal and primary forests and more vegetative parts in secondary forest. In the months Octubrer and November the consumption of vegetative parts exceeded fruit consumption.
1996年7月至1997年4月，在哥斯达黎加的科科瓦多国家公园，通过粪便分析和直接观察，对白唇西貒（Tayassu pecari）的饮食进行了研究。粪便成分包括61.6%的果实、37.5%的营养部分、0.4%的无脊椎动物和0.5%的不明物质。这些比例与南美洲报道的白唇西貒饮食比例相似，但所食用的物种有所不同。在科科瓦多，白唇西貒以57种植物的部分为食（其中37种为果实）。桑科是占比最大的科。相比之下，秘鲁亚马逊西貒的饮食主要由植物部分（棕榈科）组成。哥斯达黎加西貒的饮食包括天南星科和蝎尾蕉科的营养部分。直接观察表明，西貒有30%的进食时间用于挖掘。从挖掘地点采集的样本表明，西貒以蚯蚓为食。不同月份、季节和栖息地的饮食有所不同。它们在沿海和原始森林中吃更多的果实，在次生林中吃更多的营养部分。在10月和11月，营养部分的消耗量超过了果实的消耗量。
