Birds of the Grota do Angico Natural Monument in the semi-arid Caatinga scrublands of northeastern Brazil

an inventory of the avian fauna of the grota do angico natural monument in the caatinga of northern sergipe, brazil, revealed the presence of at least 140 species, including nine that are endemic to the caatinga and seasonal forest adjacent. despite the limited scope of the study (two expeditions in july and august, 2008), the species richness recorded at the site appeared to be typical of the region and the caatinga biome.
