“…Nevertheless, the estimated Lesser Elaenia longevity is similar to those known for other resident Brazilian species, based on Tables 1 and 2 in Lopes et al (1980) and Table 1 in Silva-Jr et al (2021). These sources document two migratory species that lived an average of 3.5 ± 1.5 years and 47 resident species that lived 4.2 ± 2.1 years on average.…”

Research on terrestrial migratory birds is incipient in Brazil. Geolocators have recently allowed tracking small migratory passerines, and such data combined with intrinsic markers such as stable isotopes has become invaluable in revealing migratory behavior. Here we used data from a long-term banding program in a Cerrado reserve in central Brazil where we also deployed geolocators to track adults of a 15g flycatcher, the Lesser Elaenia (Elaenia chiriquensis). The literature defines it as a resident or migrant that may overwinter in the Amazon or Central Brazil. Our general goals were to describe the breeding site fidelity of individuals, their migratory behavior and wintering grounds, thus assessing the migratory connectivity of the studied population. We tagged 40 birds in 2011-2012 and successfully extracted data for three recaptured individuals. We analyzed data using GeoLight and QGIS. Recapture data showed that individuals lived for at least 12yrs and that ~15% of all marked birds returned to a ~200 ± 185m radius from where it was recorded in a previous breeding season. Tracking data revealed low migratory connectivity of the studied population. One individual remained resident. The other two individuals migrated through distinct routes: one made a longitudinal northeast-southwest route and the other a cyclic migration consisting of a poleward section to south Brazil, a NW flight to the Pantanal surroundings and ending with a longitudinal NE spring migration. These are the first detailed data of the migratory movements of individual Lesser Elaenias, supporting its partial rather than obligatory migration in central Brazil. Moreover, we found that migrants overwintered in savanna-like areas, supporting previous studies. We included and discussed a list of hypotheses we expect to guide further studies on this and other intratropical migrant species, thus contributing to improving knowledge on this complex and understudied migratory system.

“…The information considered were longevity (in years), body mass (g), brood size and diet. Species longevity was compiled from publications by a compilation of several authors (Lopes et al 1980;de Magalhães and Costa 2009;Silva-Jr et al 2020;Young et al 2012). Body mass (median) was mainly based on Dunning (2007), supplemented with data from eBird (2021); brood size considered the average number of offspring of each species (Jetz et al 2008;Myhrvold et al 2015).…”

In this work we sought to evaluate the factors that influence the public's interest in wild birds sold as pets in Brazil, and the relationship of those factors with new occurrences of birds outside their natural range. We compiled the richness of bird species traded in Brazil and obtained comparative data of public interest directed to these species through the Google Trend tool. In addition, we gathered data on biological attributes and the sale price of the species in the trade, to analyze which factors would be related to public interest. Then, factors related to public interest were used to assess whether there was a relationship with these new occurrences. The main founds indicated that the public interest is greater for songbirds, omnivores, which live in more open environments and are sold at lower prices. All those factors also showed to be related to the birds that presented new occurrences. The public's preference for birds more generalist and from more open environments are important results, as such factors generally indicate greater environmental tolerance, which may favor the establishment of these birds in new environments. Therefore, it is likely that species releases or escape from captivity, combined with their life history attributes, may favor the establishment of isolates in new environments. Thus, the present results demonstrate that actions aimed at the conservation of commercialized species are essential to reduce the interregional trade of species, and consequently reduce the impact on natural populations and reduce the potential for new biological introductions.

“…A variação na intensidade de ocorrência dos indivíduos anilhados monitorados evidencia isso (Figura 4). Vale lembrar que o comedouro do Legado das Águas foi instalado há apenas três anos, o que provavelmente compreende apenas uma geração de indivíduos do local, já que Passeriformes de pequeno porte possuem em média dez anos de vida (WASSER; SHERMAN, 2010;SILVA-JR et al, 2020).…”

Bird feeders for free living birds: accessing influence on ecosystem services and ecotourism Private or public natural protected areas are considered fundamental areas for preserve biodiversity. These sites provide significant ecosystem services, and birds are a biodiversity component that provide some of these services, such as seed dispersal to maintain the forest structure (i.e., support service), and leisure promotion and ecotourism through birdwatching (i.e., cultural service). Birdwatching is a very common worldwide nature contemplation activity, and it is continuously growing in Brazil. In natural protected areas able to receive tourists, one efficient way to promote public contact with free-living birds is providing supplementary food on bird feeders. Although bird feeders can be useful to humans, different studies carried out abroad have highlighted negative impacts of these structures on bird communities and nature. Because in Brazil studies aimed to assess impacts of bird feeders are still rare, uncertainties and controversial discussions prevail. Thus, the present dissertation, organized into three chapters, discuss whether the presence of bird feeders in a forest landscape could influence the seed dispersal provided by birds (i.e., support services provisioning; one case study supports the discussions), and accesses the perception of Brazilian bird enthusiast regarding the usage of bird feeders in natural protected areas (i.e., cultural service provisioning). The obtained outcomes suggest low impact on the support service, however, because the lack of similar studies in the Neotropical region, it is still too early draw firm conclusions. Regarding the perception of Brazilians, much of the responders recognized only positive impacts (e.g., the possibility of providing environmental awareness) in detriment of negative impacts (e.g., pathogens proliferation and attracting other animals). This dissertation brings useful biological and social information to managers of natural protected areas and decision makers and serves as a basis for future studies of bird feeders in Brazil.
