Diet of Ornate Hawk-Eagle (Spizaetus ornatus)
Revista Brasileira de Ornitologia - Tập 27 - Trang 31-39 - 2019
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 ...
Is hearing believing? Patterns of bird voice misidentification in an online quiz
Revista Brasileira de Ornitologia - Tập 24 - Trang 217-227 - 2016
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...
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
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...
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
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...
The Tocantins-Araguaia Basin as a migratory route and a wintering area of Falco peregrinus (Aves, Falconidae)
Revista Brasileira de Ornitologia - - 2019
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...
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
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...
A Narrow-billed Woodcreeper, Lepidocolaptes angustirostris, nesting in a mailbox
Revista Brasileira de Ornitologia - Tập 26 - Trang 189-191 - 2018
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...
Breeding biology of the White-collared Swift Streptoprocne zonaris in southeastern Brazil
Revista Brasileira de Ornitologia - - 2014
Advocating better habitat use and selection models in bird ecology

Distinguishing females of capuchino seedeaters: call repertoires provide evidence for species-level diagnosis
Revista Brasileira de Ornitologia - - 2019
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 field research on this
group, we obs...
