The Cerrado domain is a mosaic of vegetation types at the local scale, and this environmental heterogeneity leads to high regional bird diversity. Therefore, we aimed to survey quantitative and qualitatively the bird fauna of two fragments of Cerrado and to compare them with an adjacent protected area (Estação Ecológica de Itirapina), in order to assess the heterogeneity of bird diversity in the region. The present study was conducted during 12 months from October 2006 to September 2007 in the municipality of Itirapina, Southeastern Brazil. Altogether we recorded 210 bird species. Fifty-six of them had never been detected in Estação Ecológica de Itirapina, and eleven species are new records for the whole Itirapina region. The list also includes six species that are endangered in Sao Paulo State and five endemic species of the Cerrado domain. Most species were recorded in less than 50% of the visits and exhibited low relative abundance. Primarily insectivorous species were the most common, followed by omnivores. Frugivorous birds were poorly represented. Carnivores were more abundant than usually observed in fragments. The similarity among fragments was higher than between fragments and the protected area. Considering the vegetation heterogeneity in the Cerrado domain, our results reinforce the importance of conserving fragments in order to sample this diversity.Keywords: avifauna, forest fragmentation, environmental heterogeneity. Comunidades de aves em dois fragmentos de Cerrado em Itirapina, BrasilResumo O mosaico de tipos vegetacionais que formam o Cerrado contribui para a alta diversidade de aves deste domínio. O presente trabalho teve como objetivo principal realizar os levantamentos qualitativo e quantitativo da avifauna de dois fragmentos de Cerrado e compará-los aos resultados encontrados em uma área adjacente de Cerrado (Estação Ecológica de Itirapina). O trabalho foi realizado entre outubro de 2006 e setembro de 2007, no município de Itirapina, região central do Estado de São Paulo, Brasil. Registramos um total de 210 espécies de aves. Destas, 56 ainda não haviam sido registradas na Estação Ecológica e onze espécies são novos registros para a região de Itirapina. A lista dos fragmentos inclui seis espécies ameaçadas no Estado de São Paulo e cinco espécies endêmicas de Cerrado. A maioria das espécies foi detectada em menos de 50% das visitas e apresentou baixa abundância relativa. A classificação em categorias tróficas indicou a prevalência de espécies predominantemente insetívoras, seguidas pelas onívoras. Os frugívoros foram pouco representados e a quantidade de carnívoros foi superior à geralmente encontrada em fragmentos. A similaridade encontrada entre os fragmentos foi maior que a encontrada entre os fragmentos e Estação Ecológica. Os resultados reforçam a importância da conservação dos fragmentos de Cerrado, uma vez que a heterogeneidade de tipos vegetacionais é importante para a conservação da biodiversidade local.Palavras-chave: avifauna, fragmentação florestal, heterogeneidade ambiental.

“…The bird species richness observed in this study by point counts (156 species) represented 63.2% of the known bird richness for all study area, showing the effi ciency of this method to record the most bird species of a region (Develey 2004, Anjos et al 2010, Vielliard et al 2010. Additionally, the method of point counts is very suitable when the objective is to provide controlled data on the bird abundance, being widely used in studies on bird community structure (Aleixo and Vielliard 1995, Aleixo 1999, Almeida et al 1999, Pozza and Pires 2003, Donatelli et al 2004, 2007, Lyra-Neves et al 2004.…”

The informations of bird species distribution in different habitats and the structure of their communities are crucial for bird conservation. We tested the differences in composition, richness and abundance of birds in different phytophysiognomies at Bodoquena Mountains, western Brazil, and we demonstrated the variations in richness and abundance of birds between different trophic groups. Sampling was conducted between July 2011 and June 2012 in 200 point counts arranged in the study area. A total of 3350 contacts were obtained belonging to 156 bird species. Woodland savannas, seasonal forests and arboreal savannas had higher bird abundance and richness, while riparian forests, clean pastures and dirty pastures had smaller values of these parameters. The bird community was organized according to local vegetational gradient, with communities of forests, open areas and savannas, although many species occurred in more than one vegetation type. The insectivorous, omnivorous, frugivorous and gramnivorous birds composed most of the community. These data showed how important environmental heterogeneity is to bird communities. Furthermore, the presence of extensive patches of natural habitats, the small distance between these patches and the permeability of pastures, with high arboreal and shrubby cover, are indicated as important factors to maintain the bird diversity.
