Brazilian bird collections: a decade after Aleixo & Straube (2007)
Revista Brasileira de Ornitologia - Tập 25 - Trang 254-268 - 2018
Carla Suertegaray Fontana, Thaiane Weinert da Silva, Juliana Pestana de Souza
We compiled the main results of a second diagnosis of Brazilian ornithological collections. Our starting point was the survey by A. Aleixo and F. Straube, with data up to 2005 and published in 2007. Ten years later, in 2015, curators or managers from 35 collections of birds (out of 59) answered 12 questions related to the status of the collection they curate. These collections cover all regions of...... hiện toàn bộ
Discolored and worn-out plumage in juvenile Magellanic Penguins (Spheniscus magellanicus) found ashore in southeast and northeast Brazil
Revista Brasileira de Ornitologia - Tập 26 - Trang 202-206 - 2018
Ralph Eric Thijl Vanstreels, Renata Hurtado, Leandro Egert, Luis Felipe Mayorga, Renata Cristina Campos Bhering, Pierre A. Pistorius
Magellanic Penguins (Spheniscus magellanicus) are common winter visitors of the Brazilian continental shelf. In this study we report the occurrence of discolored and worn-out plumage in juvenile Magellanic Penguins washed ashore during summer on the southeast and northeast coast of Brazil. In the affected individuais, the areas of the plumage that would normally be black or dark grey were discolor...... hiện toàn bộ
Effects of pairing Thamnophilus ambiguus males with females on the behavioral responses by males to playback
Revista Brasileira de Ornitologia - Tập 24 - Trang 300-302 - 2016
Ravel Rocon Zorzal, Charles Duca
The behavioral responses of the Sooretama Slaty-antshrike (Thamnophilus ambiguus) to playback were tested in a Restinga (sand-coastal plain) area in southeastern Brazil. Field data were collected for seven mornings, from 5:30 h to 11:00 h. Frequency data and the time period between playing the species’ song (playback) and the sighting of individuals were recorded by the observer. The following par...... hiện toàn bộ
A Narrow-billed Woodcreeper, Lepidocolaptes angustirostris, nesting in a mailbox
Revista Brasileira de Ornitologia - Tập 26 - Trang 189-191 - 2018
Marco A. Pizo
Documenting the adaptations of birds to live in urban areas is important in a context of an anthropogenically altered world where such areas may represent novel ecological opportunities for birds. Here I report on a nest of the Narrow-billed Woodcreeper Lepidocolaptes angustirostris in a wooden mailbox in a suburban area. The nest was found in the first week of November 2016 with three eggs, and l...... hiện toàn bộ

Distinguishing females of capuchino seedeaters: call repertoires provide evidence for species-level diagnosis
Revista Brasileira de Ornitologia - - 2019
Márcio Repenning, Carla Suertegaray Fontana
AbstractReliable identification of cryptic Neotropical capuchino seedeater females remains as a recurrent and non-trivial issue in field ornithology. Even in the hand, capuchino females cannot be accurately diagnosed to the species level based solely on visual plumage examination, which may present a problem for future research on this group. During 10 years of fie...... hiện toàn bộ
Nesting success of birds from Brazilian Atlantic Forest fragments
Revista Brasileira de Ornitologia - Tập 25 - Trang 77-83 - 2017
Miguel Ângelo Marini
Several aspects of the ecology of tropical birds remain unresolved both descriptively and experimentally, in spite of the high diversity of birds and the high deforestation rates. Here, I evaluate, apparently for the first time, nesting success and predation levels of open and closed-cupped nesting birds in an avian community from Atlantic Forest fragments in southeastern Brazil. The monitoring of...... hiện toàn bộ
A collection of birds from Presidente Kennedy and adjacent areas, Tocantins: a further contribution to knowledge of Amazonian avifauna between the Araguaia and Tocantins Rivers
Revista Brasileira de Ornitologia - Tập 24 - Trang 168-184 - 2016
Guilherme R. R. Brito, Guy M. Kirwan, Claydson P. Assis, Daniel H. Firme, Daniel M. Figueira, Nelson Buainain, Marcos A. Raposo
We report on a collection of birds made at a study site in Presidente Kennedy, midway between the Araguaia and Tocantins Rivers, in north-central Tocantins state, Brazil. Interesting records are presented for 22 species, most of them principally Amazonian taxa with comparatively few previous records for the state of Tocantins, and generally amplifying their local ranges either further south, from ...... hiện toàn bộ
Population viability analysis of the Mato Grosso Antbird (Cercomacra melanaria) in the Pantanal of Mato Grosso, Brazil
Revista Brasileira de Ornitologia - Tập 25 - Trang 169-175 - 2017
Paula Fernanda Albonette de Nóbrega, João Batista de Pinho, Charles Duca
Understanding the interaction between habitat loss, environmental uncertainty, demographic stochasticity and genetics are the goal of population viability analysis. Minimum viable population (MVP) size is an estimate of the number of individuals of a species that will allow the continuation of the population into the foreseeable future. Here, we analyzed the population viability of Mato Grosso Ant...... hiện toàn bộ
