Abstract

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. So, 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 realized in Amazon Rainforest was to analyze the groups of birds that were affected by the forest fragmentation in different stages of ecological succession and the results show alterations in the diversity and density of bird's species, principally among specialist species.
