Abstract
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 (Topazapella 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.
Highlights
The Brazilian Amazon has been subject to scientific study for many decades, due to its large expanse, it is still considered under studied by ornithologists (Oren & Albuquerque 1991)
The study of birds in this region over the past 100 years has resulted in the description of 16 new species and records for over 400 bird species in the area between the city of Itaituba and the southern boundary of Amazonia National Park (Oren & Parker 1997)
All sites located within the FLONA had an average similarity above 0.3 (30%), making them more similar to each other when compared to sites located outside the National Forest (Table 2, Figure 2)
Summary
The Brazilian Amazon has been subject to scientific study for many decades, due to its large expanse, it is still considered under studied by ornithologists (Oren & Albuquerque 1991). The region between the lower and middle Tapajós River in Pará State has been visited and studied for over 100 years by Brazilian and foreign ornithologists (Snethlage 1908; Oren & Parker 1997; Pacheco & Olmos 2005; Santos et al 2011; Lees et al 2013a). The study of birds in this region over the past 100 years has resulted in the description of 16 new species and records for over 400 bird species in the area between the city of Itaituba and the southern boundary of Amazonia National Park (Oren & Parker 1997). Amana was created to promote sustainable multipleuse management of forest resources; maintain and protect water resources and biodiversity; and support development of methods for the sustainable use of natural resources (DOU 2009)
