Bird diversity in a semideciduous forest of the central-western region of the state of São Paulo, Brazil

Abstract

Some bird species are considered extinction-prone as a consequence of habitat fragmentation. In order to determine whether a relatively large fragment compared to other remnants in the interior of the state of São Paulo harbors a representative number of such species we conducted Point Counts of birds in a semideciduous forest from October 2005 – December 2006. We recorded 105 forest species and both understory insectivores and canopy frugivores accounted for the greatest diversities. Other species were also typical of preserved habitats such as terrestrial insectivores and frugivores. The remnant had representative richness of fragmentation-sensitive species although some of them may not be as abundant as they used to before the event of fragmentation.
