“…The observed abundance patterns are consistent with the literature, with few species showing high values and large number of species showing intermediate and low values (Donatelli et al, 2004;Lyra-Neves et al, 2004;Dario, 2010). These results are typical of bird communities in tropical forests, with high species richness and low number of individuals in each species, except for some naturally abundant taxa (Donatelli et al, 2004).…”

The Atlantic Forest has been highly fragmented, with the Pernambuco Center of Endemism (PCE) one of the priority areas for conservation. The Mata do Cedro forest, located in Alagoas state, northeastern Brazil, is a forest fragment within the PCE surrounded by a matrix of sugarcane that acts as a refuge for several threatened bird species, some of which are endemic to the region. Here, we characterize the bird community in Mata do Cedro using measures of species abundance, frequency of occurrence, habitat use and sensitivity to human disturbance. The functional role of species was investigated with a functional dendrogram. We registered 111 species, most resident and forest dependent. The most representative trophic categories were insectivores followed by frugivores. Of the species found, 11 are highly sensitive to human disturbances and 11 are endemic to the PCE. The bird community of the fragment is highly diversified, with endemic taxa and balanced trophic categories typical of preserved tropical forests. This community structure together with the occurrence of threatened species reinforces the importance of Mata do Cedro for the maintenance of local biodiversity and ecosystem functions.

“…Bird species recorded accounted for 32 % of all species reported for Quintana Roo by Correa and MacKinnon (2011), being the order Passeriformes the most representatives with 52 % (83 species) from the total recorded. Abundance index values (PAI) showed a large number of species with low PAI, as well as few species with intermediate to high PAI compared to the pattern observed in other surveys (Aleixo & Vielliard, 1995;Lyra-Neves, Martins, Mendes, Rodrigues, & Lacerda, 2004). Bird species richness in the study was similar to other tropical forest areas with a predominance of insectivore species (e.g., Estrada, Coates-Estrada, & Meritt, 1997;Blake & Loiselle, 2001).…”

Tropical forests have undergone extensive transformation because of increasing tourism development, in addition to historic clearing for agricultural and cattle grazing activities. Altogether, these activities have had an important effect on bird diversity, reducing the habitat available to many species. In this study, the role of tropical forest remnants located between different land use types was evaluated for species diversity, composition, and distribution of the bird community at Akumal region in Quintana Roo, Mexico. Point counts were used to quantify the avifauna by habitat, and Shannon´s and Simpson´s diversity index were used to determine bird diversity. Additionally, bird species were classified according to seasonality and trophic guild by type of habitat. A total of 160 species and 50 families was recorded, of which 100 species were permanent residents, 47 winter visitors and 11 transients. Mature tropical forest and tropical forest remnants had higher species richness than those of modified environments. This study supports the importance of tropical forest remnants as shelters for bird species in landscapes with tourism developments, and the relevance of these remnants to maintaining high bird diversity.

“…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.
