The diversity of birds is directly correlated with the structure of the forest. Any interfering with the vegetation produces direct effects on the avifauna through the increase, decrease, or alternation of two key attributes: food and shelter. Thus, the composition of life in the forest is altered as changes occur in vegetation that directly interferes with the population structure of the avifauna, be those changes natural or anthropic. This study was realized in fragments of the Amazon Rainforest, and the main objective was to analyze the behavior of frugivorous and omnivorous birds in three different stages of ecological succession. In forest environments where a vertical stratification of resources occurs, these species are distributed occupying a in a high diversity of trophic niches. The diversityand density of the frugivorous and omnivorous birds in the forest fragments in medium and advanced stage of ecological succession could be directly correlated not only with the structure of the forest, but also to the fact that these birds feed almost exclusively on abundant and easy to find food sources-shrub and tree fruit of certain vegetable species that are naturally abundant in the rainforest understory layer.
