Caracterização da comunidade de aves da reserva biológica de Pedra Talhada, Estado de Alagoas

Abstract

Brazil has one of the greatest diversity of birds in the world, with about 1,197 species, where a good part of the biodiversity is located in the Atlantic Forest, included among the 25 most threatened and diverse biomes in the world and which has about 934 species of birds. The Endemism Center of Pernambuco (CEP), located in this Biome, is considered a hotspot that has about 434 species of birds. The Biological Reserve of Pedra Talhada (ReBio), part of this hotspot, has 255 species distributed in 56 families. Even with so much diversity, the Atlantic Forest suffered an intense fragmentation mainly due to factors such as real estate expansion, development of agricultural activity, among others. Given this scenario, this study has the general objective of better understanding the bird community of the Pedra Talhada biological reserve, through the following specific objectives: to characterize the species according to status and diet; determine ecological indicators such as homogeneity and heterogeneity. Listening point methods were used in a transect with 11 sampling points, allowing 96 species to be visualized, which represents about 37.64% of the birds in the ReBio.
