A new species of Campylopterus sabrewing is described from eastern Brazilian tropical dry forests occurring below 900 m asl. Its holotype (MZUSP 99024) an adult female Sítio Duboca (16°43’19’’S, 43°58’20’’W, elevation 840 m), municipality Montes Claros, state Minas Gerais. taxonomic revision based on more than 1,000 museum specimens revealed that the taxon, together with C. largipennis, diamantinensis and obscurus (with aequatorialis considered as a subjective junior synonym) should be...
Scientists have long been trying to understand why the Neotropical region holds highest diversity of birds on Earth. Recently, there has increased interest in morphological variation between and within species, how climate, topography, anthropogenic pressures may explain affect phenotypic variation. Because data are not always available for many species at local or regional scale, we limited our understanding intra- interspecies spatial Here, present ATLANTIC BIRD TRAITS, a set that includes...
Abstract: Climate‐change scenarios project significant temperature changes for most of South America. We studied the potential impacts predicted climate‐driven change on distribution and conservation 26 broad‐range birds from America Cerrado biome (a savanna that also encompass tracts grasslands forests). used 12 or precipitation‐related bioclimatic variables, nine niche modeling techniques, three general circulation models, two climate (for 2030, 2065, 2099) each species to model ranges. To...
Descriptions of avian diets currently lack consistent terminology and standardized methods. As a consequence, most available classifications, especially for tropical birds, are inconsistent often misleading. We identified 23 food categories commonly eaten by birds (e.g., seeds, fruits, insects) proposed standard names that accurately describe the diet type associated with each category granivore, frugivore, insectivore). also propose classification scheme types takes into account number...
Recent studies have argued that changes in fire regimes the 21st century are posing a major threat to global biodiversity. In this scenario, incorporating species’ physiological, ecological, and evolutionary traits with their local exposure might facilitate accurate identification of species most at risk from fire. Here, we developed framework for identifying animal vulnerable extinction fire-induced stress Brazilian savanna. The proposed addresses vulnerability two components: (1) exposure,...
Abstract Identifying endemic species and the areas of endemism delimited by them is central to biogeography. However, impact distinct taxonomic approaches on these patterns often neglected. We investigated how three different bird in Cerrado. The first two (at subspecies levels) were based traditional taxonomy biological concept. third approach was a revised alternative that sought identify evolutionarily significant units (ESUs). In this approach, after identifying taxa using taxonomy, we...
Abstract The migratory patterns of many Neotropical bird species remain largely unknown. Numerous logistic challenges prevent such studies, from research costs, often prohibitively expensive to institutions, equipment weight limitations. Therefore, it is paramount explore new possibilities in the field as abundant records citizen science platforms. In this study, we investigated spatial and temporal scarlet flycatcher Pyrocephalus rubinus using two platforms: eBird WikiAves, which provided...
A biologia reprodutiva de Suiriri affinis (suiriri-do-cerrado) e S. islerorum (suiriri-da-chapada) é descrita pela primeira vez. O ninho em forma cesto raso, sendo construído com fibras vegetais forrado por painas, todas essas camadas firmemente unidas grande quantidade teia aranha. seu exterior ornamentado liquens fragmentos folhas secas. apoiado base laterais entre dois ou mais ramos divergentes. Embora superficialmente similar, o apresenta várias diferenças, baixo, raso pelas uma...
We investigated if passerine birds act as important predators of small vertebrates within the Neotropics. surveyed published studies on bird diets, and information labels museum specimens, compiling data contents 5,221 stomachs. Eighteen samples (0.3%) presented evidence predation vertebrates. Our bibliographic survey also provided records 203 species preying upon vertebrates, mainly frogs lizards. suggest that vertebrate by passerines is relatively uncommon in Neotropics not characteristic...
We investigated the reproductive success of Campo Suiriri ( affinis ) and Chapada Flycatcher S. islerorum in Estação Ecológica de Águas Emendadas, Central Brazil. Between June December 2003, we monitored 25 nests 20 Flycatcher. The simple percentage successful was 32% for 10% Flycatcher, whereas calculated by Mayfield method 19% 14% estimated values daily survivorship rate (DSR) are as follows: egg period 0.971 nestling 0.944. For figures were 0.964 0.930, respectively. No differences DSRs...
ABSTRACT The South American Cerrado is the largest tropical savanna of world, and one most threatened biomes on Earth. Levels bird endemism in this biome are controversial, but up‐to‐date study points to 30 endemic species. In paper, I analysed recent range shift by those species, curl‐crested jay Cyanocorax cristatellus , comparing it with three other alleged endemics (lesser nothura Nothura minor chestnut‐capped foliage‐gleaner Hylocryptus rectirostris grey‐backed tachuri Polystictus...
Summary Populations of grassland birds are declining in Brazil due to profound alterations habitats. In this paper, we present recent records and range extensions for 12 threatened or little known Brazilian species: Ocellated Crake Micropygia schomburgkii , Sickle-winged Nightjar Eleothreptus anomalus Campo Miner Geositta poeciloptera Rufous-sided Pygmy-tyrant Euscarthmus rufomarginatus Sharp-tailed Grass-tyrant Culicivora caudacuta Cock-tailed Tyrant Alectrurus tricolor Cinereous...
A tesourinha Tyrannus savana é um Passeriforme (Tyrannidae) migratório que ocorre no Planalto central entre os meses de agosto e fevereiro. Sua biologia reprodutiva ainda pouco conhecida foi abordada pelo presente estudo quanto aos seguintes aspectos: período reprodutivo, tamanho da ninhada, tempo incubação permanência dos ninhegos ninho, características ninhos ovos, taxa sucesso predação. O realizado na Estação Ecológica Águas Emendadas em fragmentos do entorno, DF, nas estações...
We documented the presence/absence of eggs Trochiloecetes, Trochiliphagus, and Leremenopon lice on over 50,000 hummingbird specimens (representing 348 species plus 247 additional subspecies) in four museums USA. (i) provide sample estimates infestation prevalence. (ii) Sample parasite genus richness increased with increasing host size. (iii) Host body mass did not correlate richness, even when controlled for size effects. (iv) The prevalence Trochiliphagus Trochiloecetes infestations mass,...
É apresentada uma revisão histórica dos inventários ornitológicos conduzidos na Chapada Guimarães, centro-oeste do Brasil. A avifauna da região é caracterizada a partir de crítica todas as listas espécies produzidas por várias gerações ornitólogos, espécimes depositados em museus e meticulosos trabalhos campo. Especial atenção foi dada às publicações J.A. Allen, baseadas monumental coleção preparada H.H. Smith sua esposa no final século XIX. típica Cerrado, abrigando também amazônicas. Um...
Here we describe the habitat use, reproductive biology, diet and details of life history Mato Grosso Antbird Cercomacra melanaria , one least studied species. We located 30 nests, which 22 became active were monitored. The nest consists a deep cup, placed among dense tangles vegetation, almost always in forests Vochysia divergens ( Cambarazal ). Eggs are pinkish‐cream coloured, covered with reddish brown to purple spots blotches that concentrated around its centre larger end. Average success...
Abstract We studied the home range and habitat use of Suiriri affinis (Campo Suiriri) recently described islerorum (Chapada Flycatcher). The study was conducted in Cerrado areas (a tropical savannah) Estação Ecológica de Águas Emendadas, central Brazil. followed banded birds from January 2003 to 2004 calculated their by minimum convex polygon method. mean size 14.0 ha for S. (n = 12) 11.2 11). pairs presented high overlap ranges, while only limited overlap. observed no territorial...
The identification of predators birds' nests, crucial to a better understanding predator-prey interactions, remains poorly known. Here we provide evidence that birds, and especially passerines, may depredate nests in the Cerrado (Neotropical Savannah) Central Brazil. Data was collected primarily Conservation Unit (Estação Ecológica de Águas Emendadas) during breeding season, between 2003 2007. We report discuss details on 14 events nest predation, 12 which by mostly curl-crested jays -...
