A comparative study of bird communities in two forest fragments of the caatinga in in Pernambuco State, Brazil. Our aim in this study was to survey birds in two forest fragments of caatinga (shrubby physiognomy), and to assess similarities in species compositions. The fragments, Serra do Mudo (SM) and Fazenda Pindorama (FP), are located in Porteiras, in the municipality of Altinho, State of Pernambuco. Identification was done by observation and recognition of bird vocalizations. Field work was performed between April and September 2007, comprising 4 visits. In a sampling effort of 100 h, we recorded 138 species, distributed among 44 families: SM (112 sp) and FP (121 sp). The fragments showed higher similarity between the avifauna. The insectivores and omnivores were dominant in both areas. Two migrants were recorded: Elaenia albiceps (southern migrant) and Tringa solitaria (northern migrant). Only one threatened species was recorded: Carduellis yarrellii. Most species did not have forest abundance, as well as showed low sensitivity.
