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...
Anthropogenic noise is becoming more prevalent in the world and has been shown to affect many animal species, including birds. The impact of such was measured Neotropical urban parks assess how affects avifauna diversity species richness. We sampled bird concurrently sound pressure (noise) levels ( L eq , equivalent levels) eight green areas or located a large city (Belo Horizonte) south‐eastern Brazil over 1‐year period. points by means total richness, Fisher's alpha Shannon–Wiener indices....
South America holds 30% of the world's avifauna, with Atlantic Forest representing one richest regions Neotropics. Here we have compiled a data set on Brazilian bird occurrence (150,423) and abundance samples (N = 832 species; 33,119 individuals) using multiple methods, including qualitative surveys, mist nets, point counts, line transects). We used four main sources data: museum collections, on-line databases, literature sources, unpublished reports. The comprises 4,122 localities from 1815...
ABSTRACT Anthropogenic noise represents a major threat to various taxonomic groups of fauna, especially birds, as they primarily use sound communication. Associated with the edge effect caused by highways, has negative impact on birds. In this context, aim study was assess birds in an area intersected highway tropical forest Brazil. Eight transects were built, points perpendicular edges (10, 200, 400, 600, and 800 m), three areas: highway, pasture, control (named Forest). At each point,...
Territory size is an important ecological attribute of populations that has been considered a factor determines population density. Antbirds large group mainly insectivorous Neotropical passerines, usually well represented in bird communities from forested landscapes region. sizes for three Antbirds, Thamnophilus caerulescens (Vieillot, 1816) (Variable Antshrike), Dysithamnus mentalis (Temmink, 1823) (Plain Antvireo) e Pyriglena leucoptera 1818) (White-shouldered Fire-eye), were mapped and...
The Shrike-like Tanager (Neothraupis fasciata) is a Cerrado bird considered as near threatened. Its life history poorly known, especially its reproduction. We monitored reproduction during four breeding seasons (2003–2006) with 120 nests in protected area central Brazil. Nesting began at the end of dry season and start rainy season. incubation (13.0 days) nestling (11.7 periods were shorter than for most neotropical birds, but similar to some other tanagers. Clutch size (2–3 eggs) was...
Latitudinal differences in territorial behavior are considered to have great influence on life-history strategies of Nearctic and Neotropical birds. Most tropical birds has particularities that cannot be explained only by theories from studies temperate regions. We evaluated the system cooperative-breeding White-banded Tanager (Neothraupis fasciata) central Brazil's savanna present results stability territory site occupation, relationship between size group size, dispersal patterns....
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 -...
Leptodactylidae consists of more than 200 described species distributed throughout the Neotropics. The five in genus Crossodactylodes are only this family that complete their entire life cycle rainwater accumulated between bromeliad leaves. We surveyed bromeliads for izecksohni its type locality: municipality Santa Teresa, Brazil's Atlantic Forest. found C. 12 bromeliads. sex ratio was approximately 1:1. Males were distinguished from females by hypertrophy upper and forearms presence nuptial...
A checklist of the amphibians Santa Teresa municipality, in southeastern Brazil is presented based on fieldwork, examination specimens collections, and a literature review. This new amphibian list includes 108 species, which 106 (~98%) belong to Anura two (~2%) Gymnophiona. Hylidae was most represented family with 47 species (43%). Compared previous lists for Teresa, 14 were added, 17 previously reported removed, 13 re-identified recent taxonomic rearrangements. Of 11 (79%) first recorded...
Abstract The predator search image hypothesis predicts that predators will focus on prey are abundant and with which they have had success. However, the dilution effect a decrease in per capita chance of being depredated an increasing amount prey. We evaluated these hypotheses through artificial nest survival study. estimated during both non-breeding breeding seasons 2014 at restinga (sand-coastalplain) area southeastern Brazil. installed 450 nests (cup shaped) each season placed Common...
Demographic factors are fundamental aspects of the population ecology wild birds. However, they poorly understood in endemic and threatened birds Neotropics. In this study we demonstrate that, as tropical forest birds, a neotropical bird inhabiting highly seasonal savanna has high rates survival low fecundity. We conducted 2.5-year mark–resighting to determine survival, fecundity structure for White-banded Tanager (Neothraupis fasciata) 10 547ha protected area Cerrado, central Brazil’s...
The mutualistic relationship between plants and their pollinators may influence species’ spatial distribution, richness, abundance. We assessed the nectar availability interaction with in Grevillea banksii (Proteaceae), an alien plant Brazil. Our objectives were to study floral biology pollination system identify a G. population Restinga ecosystem (sand-coastal-plain) southeastern described behavioral parameters of pollinator-plant determined how contribute reproduction. Floral was analyzed...
Factors determining territory size of Neotropical birds are still poorly studied. However, it has been pointed out that varies according to resource availability. Here, we estimated the flavescent warbler (Basileuterus flaveolus) and evaluated its correlation with arthropod biomass. We conducted this study at a 19.3 ha grid inside 50 forest fragment, in southeastern Brazil. Territory sizes were small, did not vary significantly among seasons. Eight territories recorded during breeding season...
Intraspecific aggressive behavior usually mediates competition for breeding and non-breeding resources among females mating opportunities males. Variation in intrasexual levels across social contexts might then differ between sexes or converge due to different reasons. We studied three colonies of the polygynous Red-rumped cacique (Cacicus haemorrhous) during one season. evaluated whether frequency female-female male-male interactions (number corrected by total number individuals focal sex)...
For colonial bird species, egg hatching synchrony has been considered an important factor in their reproductive success. The Red-rumped Cacique, Cacicus haemorrhous (Linnaeus, 1766), is a Passeriformes species (Icterinae) that reproduces colonies which groups of females lay eggs at different periods during the season. objective this study was to evaluate if there variation success among C. along A total 192 nests from four were monitored Parque Estadual do Rio Doce, Minas Gerais state,...
Existing knowledge of the breeding success and life history characteristics most Neotropical bird species is scarce. Here, we help fill this gap by analyzing aspects biology Tropical Kingbird Tyrannusmelancholicus (Vieillot, 1819), which a good model for kind study as it common occurring in various environments, including urban areas, but little known about its history. We provide results concerning period, clutch size, incubation nestling periods, description nests, eggs nestlings, plants...
This study describes aspects of the life history Tropical Mockingbird Mimusgilvus (Vieillot, 1808), including breeding period, clutch size, nestlings and a list plants used for nesting. Nests were monitored in an area Restinga (sand-coastal plain) habitat protected southeastern Brazil. The data from 181 nests during five seasons (2010-2014) showed that has long season (26.1 ± 2.6 weeks) with up to two peaks active August March. pairs made four nesting attempts same season. mean (± SD) size...
Territorial systems of Neotropical birds remain poorly understood, especially considering the effect interspecific interactions. Studies on territorial behavior provide information about demography and life history, are useful for refinement conservation strategies. We assessed territories six species antbirds (Thamnophilidae) from August 2010 to May 2011 at Pedra Azul State Park, a protected area in southeastern Brazil, 30-ha sampling grid. Birds were captured, marked, followed through...
Several factors, including the site where colony was established and number of active nests can influence directly or indirectly breeding success colonial birds. The red-rumped cacique, Cacicus haemorrhous (Linnaeus, 1766), is a passerine (Icteridae) that breeds in colonies different environments. objective this study to evaluate cacique relation three environments (lake edge, forest swamp) which were an Atlantic Forest reserve southeast Brazil.
