ABSTRACT
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 porcent fruits, 37.5 porcent vegetative parts, 0.4 porcent invertebrates and 0.5 porcent unidentified material. These proportions are similar to those reported for white-lipped peccaries diet in South America, but the species consumed were different. In 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 porcent of feeding time rooting. Samples take from rooting sites suggest that peccaries fed on earthworms. Diet differed between months, season and habitats. They are more fruitsin coastal and primary forest and more vegetative parts in secondary forest. In the months Octubrer and November the comsuption of vegetative parts exceeded fruit consumption.
