The avifauna of a semideciduous seasonal forest fragment in the countryside of Barra Mansa, Rio de Janeiro, Brazil

Abstract

The Atlantic Forest is one of the richest and most threatened biomes in the world, a fact that configures it as a global hotspot. We provide here a list of bird species recorded in the municipality of Barra Mansa (RJ), during ten years of ad libitum observations in a fragment of Semideciduous Seasonal Forest, one of the most devastated phytophysiognomies of this biome. We recorded 192 species, of which 107 present some degree of forest dependency, 22 that present migratory activity, 24 that are endemic in the biome or in Brazil and 5 that are relevant to conservation as they are almost threatened or vulnerable at some level (global, national or state). Regarding the trophic guild, there was a predominance of insectivorous (n=67) and omnivorous (n=58) species, which denotes some environmental quality, but pressured by an imminent anthropization. Given the obtained results, the importance of the analyzed fragment for the maintenance of the local biodiversity becomes evident.
