The diet of the Scaly-headed Parrot (Pionus maximiliani) was studied during three consecutive years in a 250 ha semideciduous forest in southeastern Brazil. The parrots showed a generalist and seasonal diet. Seeds composed 70.4 percent of the diet of parrots, followed by flowers (20.3%), corn from plantations that surround the forest (7.7%) and fruit pulp (1.6%). In the dry season flowers constituted 38 percent of the diet and leguminous fruits comprised 41.2 percent of its diet. Parrots are important predispersal seed predators and have a high impact on the fitness of plants in semideciduous forests, due to their high consumption of seeds and flowers.254419425
