Abstract
This research was carried out from March 1990 to December 1993. It was designed to obtain data on the feeding behavior of the Yellow-chevroned Parakeet (Brotogeris chiriri) at four distinct areas of northeast Sao Paulo State. The following aspects of its feeding biology have been addressed: the plant species used as food, the items (flower, fruit, pulp, seed) included in the diet, the methods used to obtain food, and the flock size variation. Brotogeris chiriri used 45 plant species as food resource. From these it used seeds from 27 species, fruit pulp from 19 species and flowers from 16 species. There was a significant statistical variation on the methods used to gather food relative to the food item. The flock size of B. chiriri is highly variable (from one individual eating alone to about 45 individuals) on the same period of the year. The smallest average flock size was found during the breeding period of the species.1519510
