Perspectives and challenges on isotopic ecology of terrestrial birds in Brazil

Although stable isotopes have been increasingly used in ornithology since 1980 in many places, Brazil has been slow in adopting this methodology, especially when it comes to terrestrial birds. The most common elements in bird ecology studies are carbon, nitrogen, hydrogen, and oxygen stable isotopes, which provide information on diet, trophic interactions, habitat use, migration, geographic patterns, and physiology. It is important that Brazilian ornithologists become aware of the potential of stable isotope analysis in ecological studies, and the shortcomings of this tool. The use of stable isotopes to study bird ecology has great potential in Brazil, since many ecological questions about Neotropical birds can be addressed by it (e.g., resource and habitat use, migratory routes, isotopic niches, anthropogenic impacts, individual specialization). Brazilian museums and other Natural History collections can provide samples to study long-term temporal dynamics in bird ecology. Additionally, the integration of avian tissue sample information into a database may increase the collaboration among researchers and promote sample reuse in a variety of studies. All biomes in Brazil have been under pressure from anthropogenic impacts (e.g., land-use change, habitat loss, fragmentation, intensive agriculture), affecting several taxa, including terrestrial birds. Considering the negative effects of human expansion over natural areas and that stable isotopes provide useful ecological information, ornithologists in Brazil should increase their use of this tool in the future.(AU)

Rise-Up mist-netting (RUM): a mobile protocol for trapping wary territorial birds

Abstract Many bird species avoid traditional traps such as mist nets, thus alternative trapping methods are often needed. The Rufous Hornero (Furnariidae: Furnarius rufus) is one such species that was captured so far using conventional mist netting in rural areas or using nest-targeted traps, which risk nest damage and abandonment. Here we describe the novel rise-up mist-netting (RUM) protocol and its catchability for the wary and territorial Rufous Hornero in an urban area. The RUM trap allowed us quickly capturing 40 Rufous Hornero individuals even in paved parking lots and streets during the birds breeding period. The RUM is an active and targeted protocol that demands a single and quickly trainable field assistant. Therefore, it should also enable the capture of many understudied territorial but wary species. Moreover, it has enough mobility to fit studies in urban areas, and whenever researchers may deal with limited space and, at the same time, should reduce negative visual impacts to the general public of birds capturing and banding procedures.

An ornithological inventory in a reforested woodlot in western Paraná state, southern Brazil

Abstract This paper presents an ornithological inventory taken between March and December of 2017 in the Brazilian state of Paraná. Although the surroundings contain one relatively well-known location in regard to ornithology, Iguaçu National Park, several other areas merit exploration, among them the Santa Helena Relevant Ecological Interest Area (ARIE-SH). The 1,479 ha ARIE-SH is essentially a large remnant of the Atlantic Forest located adjacent to the city of Santa Helena, Paraná, which commencing in the 1980s has undergone considerable reforestation with both native and exotic species, including fruit species. Prior to censusing bird species and to better characterize the avian community, we conducted a bibliographic review of earlier ornithological studies carried out at ARIE-SH. In addition, we conducted opportunistic and unsystematic observations in nearby locations. We recorded 311 species of birds. During the current inventory, and others conducted in the area since 2016, we recorded six Atlantic Forest endemic species, five species threatened in Paraná, and two globally threatened species. Common species which showed high Index of Frequency in Lists include (in descending order) Basileuterus culicivorus, Leptotila verreauxi, Cnemotriccus fuscatus, Corythopis delalandi, Turdus leucomelas and Arremon flavirostris. Nine species observed while conducting this census (Laterallus exilis, Amazona vinacea, Herpsilochmus longirostris, Campylorhamphus trochilirostris, Casiornis rufus, Campylorhynchus turdinus, Myiothlypis flaveola, Eucometis penicillata and Sporophila palustris) are the first records for this region.

List of documented bird species from the municipality of Ubatuba, state of São Paulo, Brazil

Although preliminary surveys have been conducted at the Atlantic Forest of Ubatuba, there is no list of documented bird records from this coastline municipality. To organize such a compilation, we searched the literature and a number of different sources for all documented records of birds from Ubatuba, state of São Paulo. We further carried out a 7-year non-systematic bird inventory in different regions and elevations to document the species within the municipality. The total number of documented bird species is 417, 11% of which are endemic to Brazil. Another 26% are Atlantic Forest endemics and as many as 60 species are under threat categories, including near-threatened birds, in the state. Some 49 species of 27 families are reported from the municipality but still lack documentation. Considering historical records, no species have extinguished from the municipality. Ubatuba is one of the most studied regions along Serra do Mar in São Paulo regarding its ornithology, but there are still high-elevational gaps that will yield significant additions of species to the area with increasing surveying efforts.

Embora estudos preliminares tenham sido realizados em Ubatuba, localidade situada em área de Mata Atlântica, ainda não existe uma listagem dos registros documentados das espécies de aves deste município litorâneo. Para a realização deste compêndio foi realizada busca na literatura, assim como outras fontes, dos registros documentados das espécies de aves de Ubatuba, Estado de São Paulo. Adicionalmente, inventários não sistematizados seguindo a metodologia de transecção linear foram conduzidos ao longo dos últimos sete anos em diferentes regiões e altitudes do município para o registro documentado das espécies. O número total de espécies documentadas foi de 417, das quais 11% são endêmicas do Brasil. Outros 26% representam endemismos da Mata Atlântica e 60 espécies estão ameaçadas ou quase ameaçadas de extinção no Estado. Espécies reportadas para o município, porém sem documentação, somaram 49, incluídas em 27 famílias. Comparando-se os registros atuais com os históricos, nenhuma espécie foi extinta do município. Ubatuba é uma das regiões mais conhecidas ornitologicamente da Serra do Mar paulista, mas ainda há algumas localidades em maiores altitudes que devem trazer novos registros para a área com o aumento dos esforços de observação de aves em tais locais.
