ABSTRACT Between January and December 1996, the food habits of a relict population of jaguars were studied in 220 km 2 Linhares Forest Preserve, which comprises much of the remaining old‐growth Atlantic Forest of Espirito Santo, Brazil. Fecal analysis indicated opportunistic feeding on 24 prey species ( N = 101 scats). Mammals represented 87 percent of the total items, followed by reptiles (9.8%) and birds (2.8%). Considering prey weight, 23.4 percent of the items weighed 1–3 kg, 40.5 percent were 3–10 kg, and 27.7 percent weighed more than 10 kg. Analysis of relative prey frequency and biomass indicated that the diet was concentrated in two prey types: long‐nosed armadillo and white‐lipped peccary. Literature data suggest that forest jaguars rely on the same mammal prey over their entire geographic range. RESUMES Entre janeiro e dezembro de 1996, os hábiros alimentares de uma populaçáo da onga pinrada foram estudados na Reserva Florestal de Linhares (220 km 2 ), que cornpreende 25 porcento da floresra Atlintica primlria remanescente do Esrado do Espirito Santo, Brasil. A andise de fezes indicou o consumo de 24 esptcies de presas (N = 101 arnosrras). Mamiferos representaram 87 porcento do total de itens, seguidos por rtpteis (9.8%) e aves (2.8%). Considerando o peso das presas 23.4 porcento dos itens pesavam entre 1 e 3 kg, 40.5 porcenro de 3 a 10 kg, e 27.7 porcento acima de 10 kg. De acordo com a análise de freqütncia relariva de ocorrsncia e a estimariva de biomassa relativa, a dieta concentra‐se em dois itens: o tatu galinha e queixada. A onga pintada parece basear sua dieta nas mesmas esptcies de mamiferos ao longo de sua distribuig8o geogrlfica.
