Amana National Forest (FLONA Amana) is located on the left bank of the middle Tapajos River, in the interfluve of the Tapajos and Madeira Rivers, state of Para, Brazil. I performed a "Rapid Ecological Assessment" (REA) on the bird communities of the park to identify important areas for avian conservation and areas where activities could impact bird communities. Field surveys were carried out at the end of the rainy season and at the beginning of the dry season. Nine points distributed among five sites were sampled within Amana or very close to its borders. Three approaches were used to survey the avifauna of each point: (a) a quantitative approach using mist nets, (b) a qualitative approach using field observations with binoculars, and (c) interviews with local residents. With a sampling effort of 3,320 net hours, interviews with local residents, and approximately 60 additional hours of visual observations, 247 species of birds were recorded belonging to 51 families. Eight taxa are considered endemic to the interfluve of the Tapajos/Madeira Rivers. Two species are on IUCN's Red List of endangered birds (Penelope pileata and Guaruba guarouba), and the known distribution of two species (Topaza pella and Discosura longicaudus) is extended by our surveys. Two activities within Amana were detected to have possible negative impacts on avifauna, specifically hunting and gold and cassiterite mining.
