  1. Different authors have used different methods and nomenclatures to describe bird nests of the Neotropical region, leading to mud- dled terminology which makes comparisons among published data difficult. The present study suggests a standardization…
  2. The island of Santa Catarina lies in the Atlantic Forest Domain of southern Brazil, one of the most threatened ecosystems on the planet. It holds a wide variety of habitats, ranging from sand dune ‘restingas’ to mature rain forest. We report, for…
  3. We investigated if passerine birds act as important predators of small vertebrates within the Neotropics. We surveyed published studies on bird diets, and information on labels of museum specimens, compiling data on the contents of 5,221 stomachs.…
  4. Anomalias ou deformações são raramente encontradas em aves silvestres ou, ao menos, pouco reportadas na literatura. O enfisema subcutâneo é uma condição anormal caracterizada pela presença de ar ou gás sob a pele que pode, em alguns casos, se…
  5. Tropical wet forests are commonly perceived as stable and constant envi- ronments. However, many rain forest organisms reproduce seasonally. To understand the proximate regulation of life history events in tropical organisms, we asked three…
  6. “Campos rupestres” comprises the open vegetation growing above 900 m altitude mainly along the Espinhaço Range, eastern Brazil. We presents the first thorough assessment concerning the bird community structure and dynamics in campos rupestres of…
  7. Birds of a forest remnant in the Iron Quadrangle of Minas Gerais, southeastern Brazil. ABSTRACT - The Iron Quadrangle (IQ) is a region of southeastern Brazil known for having good-quality mineral deposits of worldwide economic importance. The iron…
  8. We surveyed the avifauna of Alto do Palácio, Serra do Cipó National Park, Minas Gerais state, Brazil. The park lies in the southern Espinhaço range, a significant biogeographical barrier that separates the forest areas of the Atlantic Forest on its…

  10. ABSTRACT: The play behavior of a Sharp-shinned Hawk (Accipiter striatus) chasing a flock of White-naped Jay (Cyanocorax cyanopogon). Play behavior in birds is difficult to recognize and interpret, and poor documented in Brazil. In this note, we…
  11. Recent studies in the field of behavioural ecology have revealed intriguing variation in behaviour within single populations. Increasing evidence suggests that individual animals differ in their average level of behaviour displayed across a range of…
