Diet of Ornate Hawk-Eagle (Spizaetus ornatus)
Revista Brasileira de Ornitologia - Tập 27 - Trang 31-39 - 2019
Fagner Daniel Teixeira, Elisa Paraíso Mesquita, Michele Alves Ferreira, Felipe Carvalho de Araújo
The Ornate Hawk-Eagle (Spizaetus ornatus) is a top predator and inhabits mainly preserved forests. It occurs from Mexico to Argentina and throughout Brazil, where it is threatened by extinction. It hunts birds, mammals and reptiles, picking up both on the ground and on the branches in the forest. Here we report data on a pair and one young individual of this species registered in the southeast of ...... hiện toàn bộ
Is hearing believing? Patterns of bird voice misidentification in an online quiz
Revista Brasileira de Ornitologia - Tập 24 - Trang 217-227 - 2016
Bento Collares Gonçalves, Gonçalo Ferraz
This study aims to uncover patterns of species identification error in bioacoustic surveys of central Amazon birds. To quantify errors, we developed an on-line quiz based on vocalizations of an undisclosed set of 41 antbird (Thamnophilidae) and woodcreeper (Dendrocolaptinae) species. We invited experts to answer the quiz and obtained 820 answers from 20 participants. The answers were compared to t...... hiện toàn bộ
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
Reproductive biology and nest-site selection of the Mato Grosso Antbird Cercomacra melanaria in the Brazilian Pantana
Revista Brasileira de Ornitologia - Tập 22 - Trang 270-277 - 2014
Bianca Bernardon, Paula Fernanda Albonette de Nóbrega, João Batista de Pinho
Economic activities, such as extensive cattle ranching, may seriously threaten the types of forest most important to the Mato Grosso Antbird Cercomacra melanaria, and information on reproductive biology is essential for defining sound conservation and management strategies for the species. Here, we report on the reproductive biology of this species in the Brazilian Pantanal, focusing on attributes...... hiện toàn bộ
The Tocantins-Araguaia Basin as a migratory route and a wintering area of Falco peregrinus (Aves, Falconidae)
Revista Brasileira de Ornitologia - - 2019
Túlio Dornas, Willian Menq, Tiago Junqueira, Estevão F. Santos
The Peregrine Falco peregrinus, is an Nearctic migrant to Brazil where its status in central Brazil is still poorly known. Herein we present a compilation of records of the species from the state of Tocantins and comment on its use of a wintering site in the state of Goiás. These records show that the Tocantins-Araguaia River Basin is a migration route for the species, and therefore a mid-continen...... 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
