“…This is consistent with Foster (1975) with 8.1% at 10°N and this study near Manaus, Brazil with 12.7% at 2°S. Geographical patterns, such as latitudinal and environmental gradients in molt–breeding overlap, remain difficult to confidently discern, however, because so few community‐level datasets are available, and because molt–breeding overlap frequencies likely depend on the biome, region, and taxonomic composition of the avian community (Poulin et al 1992, Mallet‐Rodrigues 2005, Magalhães et al 2007). For example, we primarily studied understory passerines, and molt–breeding overlap frequency of the community may increase or decrease as other members of the community are included.…”

Th e energetically challenging periods of molting and breeding are usually temporally separated in temperate birds, but can occur simultaneously in tropical birds, a condition known as molt -breeding overlap. Here, we document great variation in the timing and duration of molting and breeding, and in the extent of molt -breeding overlap, among 87 species of understory passerines in central Amazonia. We analyzed molt and breeding from 26 871 birds captured over a 30-yr period near Manaus, Brazil. Although most species typically bred during the late dry season (about October through January), many thamnophilids apparently bred year-round, whereas a few other species from a variety of families bred mainly during the wet season (about January through May). Of all breeding birds with an active brood patch, 12.7% were simultaneously molting. Molt -breeding overlap was more frequently observed among suboscines (13.3%), especially thamnophilids (23.0%), than oscines (6.4%). Some families had Ͻ 5% molt -breeding overlap frequency, including Tyrannidae (4.4%), Tityridae (0.0%), Pipridae (1.5%), Turdidae (0.0%), and Th raupidae (0.0%), indicating that not all tropical species exhibit molt -breeding overlap. Among 31 well-sampled species (n Ն 15 brood patches), variation in molt -breeding overlap frequency was positively correlated with each species ' average duration of fl ight feather replacement (range 98 -301 d). We also measured feather growth rates of individual birds in nine species; in fi ve of these, slower-growing feathers increased with an individual ' s probability of having molt -breeding overlap. Among furnariids, molt -breeding overlap occurred either at the beginning or end of the molt cycle, suggesting that physiological mechanisms typically separate molting from breeding. Th amnophilids showed a much diff erent pattern; molt -breeding overlap occurred at any stage of feather replacement, apparently not regulated to be independent of breeding. Th ese results reveal substantial life-history variation among Amazonian birds. Future work to resolve the physiological regulation of molting and breeding in tropical birds will greatly contribute to understanding these patterns and their relevance to avian diversity.

“…Compared to previous studies in the PCE, the present study found higher species richness than Lyra-Neves et al (2004), andLobo-Araújo et al (2013), probably due to particularities of different forest types, the small sizes of the fragments or differences in sampling effort and methodologies. Conversely, Roda (2004), Magalhães et al (2007) and Farias et al (2007) recorded higher values of 125, 151 and 140 species, respectively, in contrast to the 111 found in this study. In Alagoas, Daher et al (2013) registered 150 and 110 species in Madeiras and Fazenda Brejo, respectively.…”

The Atlantic Forest has been highly fragmented, with the Pernambuco Center of Endemism (PCE) one of the priority areas for conservation. The Mata do Cedro forest, located in Alagoas state, northeastern Brazil, is a forest fragment within the PCE surrounded by a matrix of sugarcane that acts as a refuge for several threatened bird species, some of which are endemic to the region. Here, we characterize the bird community in Mata do Cedro using measures of species abundance, frequency of occurrence, habitat use and sensitivity to human disturbance. The functional role of species was investigated with a functional dendrogram. We registered 111 species, most resident and forest dependent. The most representative trophic categories were insectivores followed by frugivores. Of the species found, 11 are highly sensitive to human disturbances and 11 are endemic to the PCE. The bird community of the fragment is highly diversified, with endemic taxa and balanced trophic categories typical of preserved tropical forests. This community structure together with the occurrence of threatened species reinforces the importance of Mata do Cedro for the maintenance of local biodiversity and ecosystem functions.

A conservação da biodiversidade nas atuais condições de pressões antrópicas, pressupõe a implantação de unidades de conservação. No Município de João Pessoa (PB), a Mata do Buraquinho, consiste em unidade de conservação de proteção integral - refúgio de vida silvestre. Assim, o objetivo desta pesquisa foi elaborar um check list da avifauna desta unidade de conservação, no período de março de 2017 a fevereiro de 2018. No inventário, aplicou-se o método das Listas de Mackinnon, onde foram obtidas 84 listas de 10 espécies. Foram registradas 113 espécies de aves, representadas por 34 famílias, sendo as de maior riqueza de espécies Tyrannidae e Thraupidae, com 30 espécies (27%), enquanto 28 espécies (25%) são consideradas indicadoras de alterações ambientais. Foram registrados oito táxons endêmicos do Brasil e do Bioma Mata Atlântica, no Centro de Endemismo Pernambuco, Picumnus pernambucensis, Touit surdus, Xiphorhynchus atlanticus, Xenops minutus alagoanus, Iodopleura pipra leucopygia, Hemitriccus griseipectus naumburgae e Ramphocelus bresilius. Seis táxons estão ameaçados de extinção, Leptodon forbesi (EN), Touit surdus (VU), Xenops minutus alagoanus (VU), Iodopleura pipra leucopygia (CR) e Hemitriccus griseipectus naumburgae (VU). Os impactos ambientais negativos constatados para a avifauna são a coleta e o corte seletivo de plantas, a poluição hídrica, a pesca, a caça, as queimadas, a poluição sonora e a (re)introdução de espécies da fauna nativa. A observação de aves e a educação ambiental envolvendo as comunidades em torno da mata são instrumentos de inclusão social na conservação desta área protegida. Pode-se concluir que esta unidade de conservação consiste em um remanescente de extrema relevância ecológica para a conservação da avifauna da Mata Atlântica.
