ABSTRACT
We inventoried the birds from Serra do Aracá region, state of Amazonas. The region encompasses a high diversity of vegetation types, including white sand forests and campinas, terra firme and flooded forests, montane forests and tepuis. We recorded 416 bird taxa in 69 families through captures with mist nets, tape recording of bird voices, and collection of voucher specimens. A large proportion of them (61%) were recorded in a single vegetation type. Qualitative estimates suggest that approximately 580 bird species occur in the region. The avifauna of the Aracá region has a mixed biogeographic composition, with species typical of both margins of the Rio Negro occurring sympatrically. Additionally, species whose distributions are restricted to three areas of endemism for Amazonian birds (Imeri, Guiana and Pantepui) were recorded in the region. Rare landscapes in the Brazilian Amazon are found in the Serra do Aracá region. Additionally, we recorded endemic and rare birds, highlighting the value of the region for conservation. The Serra do Aracá State Park officially protects montane forests, terra firme forests and tepuis. We suggest that the large extension of white sand campinas and igapó forests at the southern portion of Serra do Aracá should be also preserved in order to improve the representation of the rich natural heritage of the region.
