Article
The swallow-tailed hummingbird Eupetomena macroura is a synanthropic species currently in range expansion through southern Brazil. Although common, little is known about its breeding biology. We gathered breeding records from citizen science platforms to map the breeding range, assess egg-laying seasonality in Brazilian biomes through circular stat...
Article
The Striped Cuckoo (Tapera naevia) is an obligate brood parasite with poorly understood breeding habits. Here, we describe the reproductive biology of Striped Cuckoos parasitizing Rufous-fronted Thornbird (Phacellodomus rufifrons) nests in the Cerrado of central Brazil and discuss parasite adaptations. Striped Cuckoos parasitized 38.5% of Rufous-fr...
Article
Body size mediates life history, physiology and inter- and intra-specific interactions. Within species, sexes frequently differ in size, reflecting divergent selective pressures and/or constraints. Both sexual selection and differences in environmentally mediated reproductive constraints can drive sexual size dimorphism, but empirically testing cau...

A major barrier to advancing ornithology is the systemic exclusion of professionals from the Global South. A recent special dossier, Advances in Neotropical Ornithology, and a shortfalls analysis therein, unintentionally followed a long-standing pattern of highlighting individuals, knowledge, and views from the Global North, while largely omitting...
Article
Filial cannibalism (cannibalistic infanticide) is a common strategy among raptors though rare among other groups of birds. We describe the first case of possible parental infanticide followed by cannibalism by an adult and nestmates of Red-legged Seriema (Cariama cristata) in a brood of 3 in the Cerrado (savanna-like) ecosystem. A 20 min video reco...
Article
The spatial distribution of Neotropical birds at local scales is often associated with plant successional stages and unique microhabitats such as bamboo stands and treefall gaps. Only 15% of the Atlantic Forest remains, yet this habitat is home to more than 200 endemic birds. Understanding the distribution of bird species within the Atlantic Forest...

Apex predators are threatened globally, and their local extinctions are often driven by failures in sustaining prey acquisition under contexts of severe prey scarcity. The harpy eagle Harpia harpyja is Earth's largest eagle and the apex aerial predator of Amazonian forests, but no previous study has examined the impact of forest loss on their feedi...
Article
The degree of habitat specificity determines the distinctive ways that birds respond to land-use and climate change. Information on habitat-use, movement potential and sensitivity to human disturbance can promote reliable predictions on species response to spatial and temporal global changes. Here, we made an extensive review about habitat-use of 5...

Biodiversity loss is currently one of the most important societal concerns worldwide, and it is caused mainly by habitat loss and fragmentation, biological invasion, and climate change (Vitousek et al. 1996, Newbold et al. 2015, Bellard et al. 2016). Introduced species can have positive effects on human well‐being, especially when used for liveliho...
Article
Characterizing wildlife conservation problems is essential to properly inform conservation planning, and requires detailed knowledge on critical life stages, such as reproduction. Large tropical raptors often require large emergent trees to build their huge nests. However, large emergents are also in heavy demand by the timber industry. Here, we re...

The White-throated Kingbird (Tyrannus albogularis) is a widespread species in north-central South America, where it inhabits a variety of open to semi-open habitats. The breeding biology of the species is almost unknown. We describe the reproduction of the species based on 34 nests found in southeastern Brazil and eastern Bolivia since 2004, and eg...
Article
Intraspecific aggressive behavior usually mediates competition for breeding and non-breeding resources among females and for mating opportunities among males. Variation in intrasexual aggressive levels across social and breeding contexts might then differ between sexes or converge due to different reasons. We studied three colonies of the polygynou...

Philornis larvae and pupae were collected in nestlings of Neothraupis fasciata (Lichtenstein), the White-banded Tanager (Passeriformes, Thraupidae), in three breeding seasons, between October and November 2003‑2005 in a reserve in central Brazil. Here, we present biological data, diagnosis to the recognition of the species and a key to the segregat...
Article
Historical biases towards the study of Palearctic and Nearctic bird migration systems has resulted in a dearth of information on the ecology of intratropical migrants, which likely also play important ecological roles within their communities. For instance, there is little information on the foraging ecology and breeding biology of co‐occurring mig...

Songbirds must annually undergo two energetically demanding but important activities: breeding and feather molt. Due to the high energetic investment that each demands, these two events are generally not carried out simultaneously. However, substantial variation in the level of annual reproductive investment among populations may result in variatio...
Article
Predation is the main cause of nest failure among birds and, therefore, a strong selective agent. To fully understand patterns of nest predation, determining the identities of nest predators is crucial. Information about nest predators in the Neotropics, however, is largely anecdotal and not easily accessible in the literature. Our objective was to...
Article
Several aspects of the ecology of tropical birds remain unresolved both descriptively and experimentally, in spite of the high diversity of birds and the high deforestation rates. Here, I evaluate, apparently for the first time, nesting success and predation levels of open and closed-cupped nesting birds in an avian community from Atlantic Forest f...

Descriptions of avian diets currently lack consistent terminology and standardized methods. As a consequence, most available classifications, especially for tropical birds, are inconsistent and often misleading. We identified 23 food categories most commonly eaten by birds (e.g., seeds, fruits, and insects) and proposed standard names that accurate...
Article
Throughout their annual cycle, migrants often adopt different foraging and microhabitat usage strategies. Previous studies treat migrants as niche-trackers/niche-followers, i.e., they track similar niches along their annual cycle, almost exclusively based on food resource availability, which is inferred based on the climate at either the wintering...
