Birds are the best-known vertebrate group, although many localities in the world are considered to be knowledge gaps. This is the case of many little-known environments in the Amazon biome, the world’s largest tropical forest. Here, we present a survey of birds in the upper Purus basin, comprising the municipalities of Manoel Urbano and Feijó in the Brazilian state of Acre, and Boca do Acre and Pauini in the state of Amazonas. In this region, poorly-studied habitats, such as open rainforest dominated by palms or bamboo, still predominate. We recorded 452 bird species during 45 field trips between May and July in 2016, and June to August in 2017. Twenty-four of these species are associated with bamboo habitat, 28 are endemic to the southwestern Amazon basin, and seven are threatened with extinction. This high diversity is typical of the western Amazon basin, one of the richest regions in the world in the number of species, due to the heterogeneity of the local environments. The data presented here highlight the importance of the region for the conservation of birds, including species typical of the western Amazon, some of which are still poorly-known.
AVIFAUNA OF THE SACRED SOIL OF GUARAPIRANGA (SÃO PAULO, BRAZIL): The avifauna of São Paulo, the largest Brazilian city, is one of the most studied in Brazil. However, some areas are lacking basic studies on the avifauna, including those under intense pressure from urban growth and deforestation. Here we present a list of bird species occurring in the Solo Sagrado do Guarapiranga (23°45’00”S, 46°44’00”W), an urban park in southern São Paulo. We carried out monthly bird surveys from July 2008 to June 2009, using transect method. After 250 hours of observations, we recorded 180 species, including 31 species endemics to Atlantic Forest and two species that are globally threatened. The insectivorous, omnivorous and frugivorous species were the most represented feeding guilds, with 70, 39 and 21 species, respectively. Occasional and rare species composed the community majority. The high species richness and the presence of threatened species indicate the importance of the area to the bird’s conservation in the largest Brazilian city.
O suiriri-cinzento (Suiriri suiriri) apresenta ampla distribuição na América do Sul, estando a subespécie S. s. burmeisteri restrita a fitofisionomias semiabertas dos biomas Cerrado, Caatinga e Pantanal, cuja extensão predomina em território brasileiro. No estado de São Paulo, a escassez de registros e de informações sobre a espécie a levou a ser considerada criticamente ameaçada anteriormente. Aqui, apresentamos novos registros, alguns mais a sudeste do que aqueles conhecidos para o estado, os quais conferem uma pequena expansão de distribuição local. Além disso, revisamos a distribuição da espécie no estado de São Paulo.
This note presents the first documented record of Least Nighthawk, Chordeiles pusillus (Gould, 1861), in São Paulo state, Brazil. The species was observed on four occasions (January 31, April 25, and July 27, 2016; April 27, 2017) in a sandy-rocky habitat on the left bank of Grande river, Mira Estrela municipality. This record is at least 300 km from the previously known occurrences of the species.
Muçunungas are vegetation formations in sandy soils, similar to restingas in structure and composition, ranging from grassy woody (GL) to low-density trees or muçununga forests (FM). Although some birds are known for this phytophysiognomy, few data are available on the structure of their communities, and on the ecological resources' use. This research aims to present the first commented list on the birdlife of muçunungas, and to describe how they share the ecological resources in different formations. Five areas of muçunungas having different vegetation structures were sampled in southern Bahia, Brazil, between 2011 and 2019. We recorded 216 species; 32 endemics to the Atlantic Forest and 14 threatened with extinction. The most abundant feeding guilds were insectivores (77 species), omnivores (53), and frugivores (32). A total of 109 species were recorded in FM and 183 in GL. Strictly forest birds prevailed in FM (66 %), and forest, semi-forest, and open-area species were detected in similar amounts in GL. Generalist birds have prevailed in muçunungas, sharing many species with the surrounding environments, as in restingas. Due to the paucity of specific public policies, and similarities of muçunungas and restingas, we suggest that similar conservationist strategies could be applied to birds in these two environments of the Atlantic Forest.
A região do município de Três Lagoas é considerada um dos maiores polos mundiais de produção de celulose. Nas fazendas de produção é comum que animais ocupem as áreas de vegetação nativa e de cultivo. Este estudo apresenta o levantamento da avifauna realizado em uma fazenda no município de Três Lagoas, estado do Mato Grosso do Sul, Brasil, que cultiva Eucalyptus para produção de celulose e papel. Os dados foram obtidos em remanescentes de vegetação nativa e plantios de eucalipto no período de agosto de 2007 a novembro de 2016, sendo efetuadas 28 campanhas. Para tanto, foram aplicados os métodos de pontos, transecção e registros não sistematizados, totalizando um esforço amostral de 606,7 h. Foram registradas 308 espécies, das quais duas estão ameaçadas de extinção nos âmbitos nacional e ou mundial, Crax fasciolata e Urubitinga coronata. Dez e sete espécies são endêmicas do Cerrado e da Mata Atlântica, respectivamente. No que se refere à frequência de ocorrência das espécies ao longo das campanhas, 141 espécies foram consideradas regulares, sendo que as demais, ocasionais ou raras. Além disso, pelo menos 40 espécies são migratórias. Ao todo, 156 (50,6%) espécies foram registradas nos plantios de Eucalyptus, sendo constatado que tanto aves florestais quanto campestres utilizam esse tipo de ambiente, conforme a altura ou idade do talhão. Esperamos que este estudo auxilie no desenvolvimento de processos de licenciamento ambiental e de novas políticas públicas para a conservação da biodiversidade.Palavras-chave: avifauna; Cerrado; conservação; Mata Atlântica; plantação de eucalipto. COMMUNITY OF BIRDS IN A MOSAIC OF Eucalyptus AND NATIVE VEGETATION IN TRÊS LAGOAS, MS, BRAZIL.One of the largest wood cellulose production areas worldwide is located in the municipality of Três Lagoas. Encounters with animals are not rare in these areas, and in this study we present the results of an avifauna monitoring conducted in an Eucalyptus farm in the municipality of Três Lagoas, in areas cultivated for cellulose and paper production. The data was collected in remnants of native vegetation and Eucalyptus plantations from August 2007 to November 2016, during 28 field campaigns. For this, we applied pointcount, transection and non-systematized sampling methods, totaling a sample effort of 606.7 h. A total of 308 birds were registered, of which two are endangered at the national or world level: Bare-faced Curassow (Crax fasciolata) and Crowned Eagle (Urubitinga coronata). Ten and seven species are endemics of Cerrado and Atlantic Forest, respectively. Over these ten years in the study area, 142 species were considered regular and the remaining was classified as occasional or rare. In addition, at least 40 species are migratory. A total of 156 (50.6%) birds distributed among forest and grasslands species were found in the Eucalyptus plantations attesting that both can use this type of environment, according to the height or age of Eucalyptus trees in each plot. We hope this survey will be useful for the development of environmental lice...
