The feeding ecology of the maned wolf (Chrysocyon brachyurus) was studied from 1998 to 2002 in the Ecological Station of Itirapina, São Paulo State, southeastern Brazil, including estimates of prey number and biomass consumption. A total of 325 faecal samples was collected in the area. The species is omnivorous, with a broad diet including 68 species or morphospecies of fruits and animals. Armadillos (Dasypodidae), wolf's fruit (Solanum lycocarpum) and small mammals (mostly Clyomys bishopi) were the bulk of the diet, comprising 72.8 % of the total estimated biomass consumed (185,323.4 g). In terms of frequency of occurrence, on the other hand, only small mammals and other miscella-neous fruits yielded 43.4 % of the total occurrences (N = 1,054). Animal prey ranging from 0.01 and 0.1 Kg were the most captured category, resulting in 44.2 % of 507 captured animals. The maned wolf seems to be seasonally opportunistic, at least for fruits and insects, as indicated by the variation of the consumption of these items along the year. The higher consumption of fruits and animals characteristic of savannah can be an important factor to consider in future management plans for the species.
