Avian Assemblages in Forest Fragments do not Sum to the Expected Regional Community in the Brazilian Atlantic Forest.

ABSTRACT: While bird diversity in the Atlantic Forest can be considered well-known, how the communities have been affected by deforestation and habitat fragmentation is not. We studied birds in 10 forest fragments of distinct sizes (all originally within the Atlantic Forest) in southern Bahia. In 5,391 bird encounters, we found 251 species, with 46 endemics and eight considered globally vulnerable or endangered. We also compiled a list of the 380 species that should comprise the expected regional assemblage, and found that only 66% of these species were present in all the fragments combined. Only 9% of all observed species were found in all fragments. The largest fragment (700 ha) had the greatest number of endemic species (40), and seven threatened species. All fragments had some conservation-impor
