Ecological responses of bird communities in aquatic-terrestrial transition zones (ATTZs) are only partially understood. The aim of this study was to evaluate community structure of birds in different macrohabitats of ATTZs from a protected area in the Pantanal wetland, Brazil. The survey of birds was carried out in three types of macrohabitats: Erythrina fusca Lour. monospecific forest, shrubland and pioneer polyespecific forest, and flooded grassland. The bird community living within the ATTZ varied according to macrohabitat type and period of the wetland landscape. We emphasise the importance of this protected area to biodiversity. Employ greater environmental control is required, since the region is not exempt from direct and indirect impacts derived from the Upper Paraguay River Basin.
