Cranial osteology and taxonomy of albatrosses of genus Dimedea linneaus, 1758 and Thalassarche reichenbach, 1853 (procellariformes: Diomeidae)
Provedor de dados: 84
Autores: Dénes,Francisco V.; Silveira,Luís Fábio.
The currently accepted albatross taxonomy, based on characters of external morphology, plumage patterns, tail shape, bill size and coloration, organization of the plates of the bill, and, more recently, molecular data such as cytochrome-b gene sequences, resulted in a division of the family Diomedeidae into four genera: Diomedea, comprising the great albatrosses; Phoebastria, the North Pacific albatrosses; Thalassarche, the mollymawks; and Phoebetria, the sooty mollymawks. However, there are only a few, old studies on albatross osteology, which focused mostly on supra-generic relationships. Research on the group's taxonomy and anatomy is important in order to establish a secure basis for the identification of each species, including the differences between...

Abstract The White-collared Kite (Leptodon forbesi) is an endemic and threatened raptor of the Brazilian Atlantic Forest. Here we present the known records of the species, describe the vegetation types where it was found and show Ecological Niche Models generated using Maxent algorithm. Most of the presence data were recorded in open ombrophilous forest and seasonal semideciduous forest in the states of Alagoas and Pernambuco. Maxent model had a good performance (AUC = 0.982 ± 0.004 SD), showing higher suitability for the species from Paraíba to Alagoas states. Maxent average model revealed a distribution range of 20,344 km² and an area of occupancy of 1,636.89 km². The most suitable areas for the species are those near watercourses and streams. We suggest...

A avifauna da região de Vila Bela da Santíssima Trindade, Mato Grosso
Provedor de dados: 84
Autores: Silveira,Luís Fábio; d'Horta,Fernando Mendonça.
A avifauna da região de Vila Bela da Santíssima Trindade (incluindo aí o município de Pontes e Lacerda), Mato Grosso, foi amostrada no final do mês de julho de 1997. Para este levantamento foram utilizados diferentes métodos, que resultaram num total de 312 espécies de aves. Os resultados desta campanha foram comparados com aqueles obtidos por Johann Natterer e Willis e Oniki, que passaram por esta mesma região no século XIX (década de 1820) e na década de 1980, respectivamente. Para a região do Vale do Guaporé temos, quando somados os resultados de todos os autores, um mínimo de 472 espécies de aves, e extinções locais não são reportadas, demonstrando um considerável grau de conservação para esta área. A maioria das espécies registradas nesta região está...

The Atlantic Forest of northeast Brazil hosts a unique biota which is among the most threatened in the Neotropics. Near-total conversion of forest habitat to sugar cane monocultures has left the region's endemic forest-dependent avifauna marooned in a few highly-fragmented and degraded forest remnants. Here we summarise the current status of 16 globally threatened species based on surveys conducted over the last 11 years. We found a bleak situation for most of these species and consider that three endemics: Glaucidium mooreorum (Pernambuco Pygmy-owl), Cichlocolaptes mazarbarnetti (Cryptic Treehunter) and Philydor novaesi (Alagoas Foliage-gleaner) are most likely globally extinct. Some positive news can, however, be reported for both Leptodon forbesi...

Boracéia Biological Station: an ornithological review
Provedor de dados: 84
Autores: Cavarzere,Vagner; Moraes,Gabriel Parmezani; Silveira,Luís Fábio.
Boracéia Biological Station, near the city of Salesópolis, SP, is located in one of the most well-defined centers of endemism in eastern Brazil - the Serra do Mar Center. While the station was established only in 1954 under the auspices of the Museu de Zoologia da Universidade de São Paulo, the avifauna of this locality had already attracted the attention of ornithologists by the 1940s, when the first specimens were collected. Here we describe the ornithological history of the Boracéia Biological Station with a review of all the bird species recorded during more than 68 years, including recent transect and mist-netting records. Boracéia's records were found in museums, literature and unpublished reports that totaled 323 bird species when recent data is...

Abstract The Belem Curassow (Crax fasciolata pinima) is one of the most endangered birds in South America, without sightings of birds in the wild for 40 years. This subspecies is nationally and internationally classified as critically endangered and close to extinction, suffering from poaching and deforestation in its range. Here we present new records of free-living individuals made on three indigenous lands in Pará and Maranhão states: in part of Terra Indígena Mãe Maria, Bom Jesus do Tocantins, Pará; in locations within the Reserva Biológica do Gurupi/Terra Indígena Alto Turiaçu, Centro Novo do Maranhão, Maranhão; and around the Terra Indígena Rio Pindaré, Alto Alegre do Pindaré, Maranhão. We also provide recommendations to protect this bird via a...

Recommendations for monitoring avian populations with point counts: a case study in southeastern Brazil
Provedor de dados: 84
Autores: Cavarzere,Vagner; Moraes,Gabriel Parmezani; Roper,James Joseph; Silveira,Luís Fábio; Donatelli,Reginaldo José.
In the northern hemisphere, bird counts have been fundamental in gathering data to understand population trends. Due to the seasonality of the northern hemisphere, counts take place during two clearly defined moments in time: the breeding season (resident birds) and winter (after migration). Depending on location, Neotropical birds may breed at any time of year, may or may not migrate, and those patterns are not necessarily synchronous among species. Also in contrast to the northern hemisphere, population trends and the impact of rapid urbanization and deforestation are unknown and unmonitored. Throughout one year, we used point counts to better understand temporal patterns of bird species richness and relative abundance in the state of São Paulo,...

Evaluation of methodological protocols using point counts and mist nets: a case study in southeastern Brazil
Provedor de dados: 84
Autores: Cavarzere,Vagner; Alves,Fernanda; Machado,Érika; Rego,Marco Antônio; Silveira,Luís Fábio; Costa,Marcos Mendonça; Calonge-Méndez,Andrés.
Despite their wide use in ornithological surveys, point counts and mist nets follow protocols developed in temperate regions, with little attention to possible modifications for tropical systems. Using these methods on a 3-month basis from December 2009-January 2011 in two forest fragments in southeastern Brazil, we wished to evaluate how long these locations needed to be surveyed with point counts for a relatively complete avifaunal inventory (at least 90% of all species and contacts), and if mist net hourly captures can equally detect numbers of species and individuals. Daily counting with four 20-min points during five consecutive days in a rain forest (MC) detected 90% of the estimated species richness after 20 h (60 20-min point counts), while 17 h...

Taxonomy and biogeography of Stephanoxis Simon, 1897 (Aves: Trochilidae)
Provedor de dados: 84
Autores: Cavarzere,Vagner; Silveira,Luís Fábio; Vasconcelos,Marcelo Ferreira de; Grantsau,Rolf; Straube,Fernando Costa.
After the description in the 19th century of two hummingbird species currently allocated to the genus Stephanoxis, Peters (1945) merged both taxa into a single species without providing any rationale. Here we re-evaluate the taxonomy and species limits of the representatives of this genus based on an extensive number of specimens. We demonstrate these taxa are better treated as full species under both the Biological and Phylogenetic Species Concepts due to their well-defined range and plumage patterns and reciprocally diagnosability. They have distinct, allopatric distributions segregated by a 160 km gap between the Serra do Mar, to the east, and Serra de Paranapiacaba, to the west, in the state of São Paulo. Stephanoxis species have ranges which are...

Geographical and seasonal distributions of the seedeaters Sporophila bouvreuil and Sporophila pileata (aves: Emberizidae)
Provedor de dados: 84
Autores: Machado,Érika; Silveira,Luís Fábio.
Many species in the genus Sporophila are migratory. Migration patterns, while poorly studied, may be influenced by seed production which can be very seasonal in some regions. The distribution of S. bouvreuil extends from the Amazon and Suriname south through a large part of the open regions of Brazil. Sporophila pileata, on the other hand, is found in southeastern and southern Brazil as well as Argentina and Paraguay. Both of these species migrate, but their movement patterns are poorly known. To better understand the geographical and the seasonal distributions of S. bouvreuil and S. pileata, we grouped the records into two categories: the breeding season (September to March) and the putative migration season (April to August). We found two areas of...

On the use of 10-minute point counts and 10-species lists for surveying birds in lowland Atlantic Forests in southeastern Brazil
Provedor de dados: 84
Autores: Cavarzere,Vagner; Costa,Thiago Vernaschi Vieira da; Silveira,Luís Fábio.
Due to rapid and continuous deforestation, recent bird surveys in the Atlantic Forest are following rapid assessment programs to accumulate significant amounts of data during short periods of time. During this study, two surveying methods were used to evaluate which technique rapidly accumulated most species (&gt; 90% of the estimated empirical value) at lowland Atlantic Forests in the state of São Paulo, southeastern Brazil. Birds were counted during the 2008-2010 breeding seasons using 10-minute point counts and 10-species lists. Overall, point counting detected as many species as lists (79 vs. 83, respectively), and 88 points (14.7 h) detected 90% of the estimated species richness. Forty-one lists were insufficient to detect 90% of all species. However,...

Morphology and vocalization support specific status of the Chestnut-headed Chachalaca, Ortalis motmot ruficeps (  ) (Aves; Galliformes; Cracidae)
Provedor de dados: 84
Autores: Tomotani,Barbara Mizumo; Silveira,Luís Fábio; Pacheco,José Fernando.
Abstract The Little Chachalaca (Ortalis motmot) is a widely distributed species in the Amazon basin, typically found in riverine habitats. There are two disjunct populations: the northern O. m. motmot and the southern O. m. ruficeps (known as Chestnut-headed Chachalaca). Here we performed a vocal, morphological and plumage comparison between these two taxa. Birds present differences in tail coloration but are otherwise undiagnosable in terms of plumage. Ortalis m. ruficeps is, however, markedly smaller and lighter than O. m. motmot, with no overlap in size or weight. We also found vocal differences between O. m. motmot and O. m. ruficeps, no overlap in geographic distributions and no signs of hybridization across its range. Based on the available data,...

Abstract We reviewed the occurrences and distributional patterns of migratory species of birds in Brazil. A species was classified as migratory when at least part of its population performs cyclical, seasonal movements with high fidelity to its breeding grounds. Of the 1,919 species of birds recorded in Brazil, 198 (10.3%) are migratory. Of these, 127 (64%) were classified as Migratory and 71 (36%) as Partially Migratory. A few species (83; 4.3%) were classified as Vagrant and eight (0,4%) species could not be defined due to limited information available, or due to conflicting data.

A taxonomic review of the Dark-winged Trumpeter Psophia viridis (Aves: Gruiformes: Psophiidae)
Provedor de dados: 84
Autores: Oppenheimer,Marina; Silveira,Luís Fábio.
The Dark-winged Trumpeter, Psophia viridis (Gruiformes, Psophiidae) is a Brazilian endemic species and includes three subspecies: Psophia viridis viridis Spix, 1825; Psophia v. dextralis Conover, 1934, and Psophia v. obscura Pelzeln, 1857, as well as P. v. interjecta Griscom &amp;amp; Greenway, 1937, whose validity has been questioned by several authors. These taxa are allopatric in distribution along the south of the Amazon River, although the precise limits of their distribution still remain unknown. This complex has never been taxonomically reviewed and this work aims to test the validity of its taxa based on the Phylogenetic Species Concept. Morphometrical characters and plumage colour patterns were analyzed, and the distribution of the taxa was also...

An overlooked hotspot for birds in the Atlantic Forest
Provedor de dados: 84
Autores: Cavarzere,Vagner; Albano,Ciro; Tonetti,Vinicius Rodrigues; Pacheco,José Fernando; Whitney,Bret M.; Silveira,Luís Fábio.
Abstract Montane and submontane forest patches in the state of Bahia, Brazil, are among the few large and preserved Atlantic Forests remnants. They are strongholds of an almost complete elevational gradient, which harbor both lowland and highland bird taxa. Despite being considered a biodiversity hotspot, few ornithologists have surveyed these forests, especially along elevational gradients. Here we compile bird records acquired from systematic surveys and random observations carried out since the 1980s in a 7,500 ha private protected area: Serra Bonita private reserve. We recorded 368 species, of which 143 are Atlantic Forest endemic taxa. Some 16 and 13 species are threatened at the global and national levels, respectively. If one accounts for...

Morphological evidence for the taxonomic status of the Bridge’s Guan, Penelope bridgesi, with comments on the validity of P. obscura bronzina (Aves: Cracidae)
Provedor de dados: 103
Autores: Evangelista-Vargas,Oscar Diego; Silveira,Luís Fábio.
ABSTRACT Penelope obscura Temminck, 1815 is a forest guan found in Brazil, Paraguay, Uruguay, Argentina and Bolivia. Three subspecies are currently recognized: Penelope o. obscura Temminck, 1815, P. o. bridgesi Gray, 1860, and P. o. bronzina Hellmayr, 1914. The limits between Penelope taxa are poorly understood since few studies have evaluated their differences in plumage, distribution and taxonomy. Based on 104 specimens deposited in ornithological collections we studied the variations in the plumage of P. obscura, including all characters that have been used to describe the included subspecies. Our results show that the plumage of these birds is extremely variable in southern and southeastern Brazil. Without any morphological and morphometric characters...

Hybridism between Cyanocorax chrysops and Cyanocorax cyanopogon (Aves: Corvidae) in Brazil
Provedor de dados: 103
Autores: Apolinario,Cristiane; Silveira,Luís Fábio.
ABSTRACT Cyanocorax chrysops (Vieillot, 1818) and Cyanocorax cyanopogon (Wied, 1821) are widespread jays. They are considered sister species according to recent molecular phylogenies. When analyzing museum specimens of both species, we found two individuals with intermediate plumage characteristics. They were collected near the range limits of both species, and we classified them as hybrids. Based on the sites where these specimens were found, we discuss the possible factors leading the interbreeding and compare our findings with information available in the literature. This is the first documented case of natural hybridization in jays in Brazil and the second case involving sister species within the New World jays.

Bird species diversity in the Atlantic Forest of Brazil is not explained by the Mid-domain Effect
Provedor de dados: 103
Autores: Cavarzere,Vagner; Silveira,Luís Fábio.
The Atlantic Forest is an excellent case study for the elevational diversity of birds, and some inventories along elevational gradients have been carried out in Brazil. Since none of these studies explain the patterns of species richness with elevation, we herein review all Brazilian studies on bird elevational diversity, and test a geometric constraint null model that predicts a unimodal species-altitude curve, the Mid-domain Effect (MDE). We searched for bird inventories in the literature and also analysed our own survey data using limited-radius point counts along an 800 m elevational gradient in the state of São Paulo, Brazil. We found 10 investigations of elevational diversity of Atlantic Forest birds and identified five different elevational...

Notes on Lagothrix flavicauda (Primates: Atelidae): oldest known specimen and the importance of the revisions of museum specimens
Provedor de dados: 103
Autores: Serrano-Villavicencio,José Eduardo; Silveira,Luís Fábio.
ABSTRACT The yellow-tailed woolly monkey, Lagothrix flavicauda (Humboldt, 1812), is a large atelid endemic to the cloud forests of Peru. The identity of this species was uncertain for at least 150 years, since its original description in 1812 without a voucher specimen. Additionally, the absence of expeditions to the remote Peruvian cloud forests made it impossible to collect material that would help to confirm the true identity of L. flavicauda during the 19th and first half of the 20th century. Until now, the specimens of L. flavicauda collected by H. Watkins, in 1925, in La Lejía (Amazonas, Peru) were thought to be the oldest ones deposited in any scientific collection. Nevertheless, after reviewing the databases of the several international museums and...
