This work was made between February 2002 and January 2003, on Payquerê Farm, localized on Balsa Nova Municipality, Paraná State, Brazil. The objects were: to quantify the time employee by A. guariba (Humboldt, 1812) eating leaves, fruits and flowers; as well as know the species of the plants used in Brown Howler monkey feeding, in a natural place of a Araucaria Pine Forest. In an all time used in feeding, the Bugre's Howlers employed: 57% eating leaves, 41% fruits and 1,7% flowers. The Howler Monkeys feeding activity were observed in 70 trees, belonging to 34 species in 19 families, including an expressive number of pioneer species and two exotic species. These results suggest a good capability of this primate to be adapted in a partial changed place and live in new places.
