Polystictus superciliaris (Wied, 1831) is a small tyrant-flycatcher endemic to mountaintops in the highlands of eastern Brazil. In this paper we present the first description of the breeding biology of P. superciliaris and estimate its reproductive success from a population inhabiting rocky outcrops. This study was conducted during 2005 in the Parque Estadual da Serra do Rola Moça, municipality of Nova Lima (20°03'S, 44°00'W), state of Minas Gerais, southeastern Brazil. Fourteen pairs of P. superciliaris were banded and monitored. The onset of the breeding season in 2005 was assumed to have been sometime before the 26th of July, while it was assumed to have ended on the 23rd of November based on the last observation of a successful brood. Clutch size was... |

O presente artigo descreve o comportamento de forrageamento e a dieta de Polystictus superciliaris (Wied, 1831), espécie pouco conhecida e de distribuição geográfica restrita às montanhas do leste do Brasil. Este trabalho foi realizado entre abril e dezembro de 2005 no Parque Estadual da Serra do Rola Moça, município de Nova Lima, Minas Gerais (20°03'S, 44°00'W). Para cada observação de forrageamento foram registrados os comportamentos de ataque, a direção e o substrato do ataque, a altura do substrato de forrageamento e a fitofisionomia onde o ataque ocorreu. Para a determinação da dieta da espécie foram feitas observações diretas de campo, sendo também analisado o conteúdo estomacal de 16 indivíduos. Polystictus superciliaris usa preferencialmente a... |

The Cerrado is now considered the most threatened biome of South America. Northwestern Minas Gerais state, in southeastern Brazil, still harbors large areas of extreme importance for biological conservation of the Cerrado. The current study provides the first thorough assessment of the avifauna of a large remnant of Cerrado vegetation in this region, the Fazenda Brejão. Data are based on a bird survey conducted from November 1998 to January 2007. This area is a private property of 20.000 ha preserved that lies in a region recognized for its palm groves, a pristine Cerrado (savannah-like vegetation) and gallery forests. Bird censuses were carried out through random transects censuses, mist-net captures and recording bird vocalizations. It was recorded 273... |
