Scientists have long been trying to understand why the Neotropical region holds the highest diversity of birds on Earth. Recently, there has been increased interest in morphological variation between and within species, and in how climate, topography, and anthropogenic pressures may explain and affect phenotypic variation. Because morphological data are not always available for many species at the local or regional scale, we are limited in our understanding of intra‐ and interspecies spatial morphological variation. Here, we present the ATLANTIC BIRD TRAITS, a data set that includes measurements of up to 44 morphological traits in 67,197 bird records from 2,790 populations distributed throughout the Atlantic forests of South America. This data set comprises information, compiled over two centuries (1820–2018), for 711 bird species, which represent 80% of all known bird diversity in the Atlantic Forest. Among the most commonly reported traits are sex (n = 65,717), age (n = 63,852), body mass (n = 58,768), flight molt presence (n = 44,941), molt presence (n = 44,847), body molt presence (n = 44,606), tail length (n = 43,005), reproductive stage (n = 42,588), bill length (n = 37,409), body length (n = 28,394), right wing length (n = 21,950), tarsus length (n = 20,342), and wing length (n = 18,071). The most frequently recorded species are Chiroxiphia caudata (n = 1,837), Turdus albicollis (n = 1,658), Trichothraupis melanops (n = 1,468), Turdus leucomelas (n = 1,436), and Basileuterus culicivorus (n = 1,384). The species recorded in the greatest number of sampling localities are Basileuterus culicivorus (n = 243), Trichothraupis melanops (n = 242), Chiroxiphia caudata (n = 210), Platyrinchus mystaceus (n = 208), and Turdus rufiventris (n = 191). ATLANTIC BIRD TRAITS (ABT) is the most comprehensive data set on measurements of bird morphological traits found in a biodiversity hotspot; it provides data for basic and applied research at multiple scales, from individual to community, and from the local to the macroecological perspectives.

The red-tailed Amazon parrot (Amazona brasiliensis) is a threatened species of psittacine bird that inhabit coastal regions of Brazil. In view of the threat of this species, the aim of this study was to perform a health evaluation in wild nestlings in Rasa Island, determining the prevalence of enterobacteria and infectious agents according to type of nest. Blood samples were collected from 64 birds and evaluated for antibodies of Chlamydia psittaci by commercial dot-blot ELISA. Cloacal and oropharyngeal swabs samples were collected from 23 birds from artificial wooden nests, 15 birds from PVC nests and 2 birds from natural nests for microbiological analysis. Swab samples were collected from 58 parrots for C. psittaci detection by PCR and from 50 nestlings for Avian Influenza, Newcastle Disease and West Nile viruses’ detection analysis by real-time RT-PCR. Ten bacterial genera and 17 species were identified, and the most prevalent were Escherichia coli and Klebsiella oxytoca. There was no influence of the type of nest in the nestlings’ microbiota. All samples tested by ELISA and PCR were negative. There is currently insufficient information available about the health of A. brasiliensis and data of this study provide a reference point for future evaluations and aid in conservation plans.

O uso da microbiologia como ferramenta para a conservação de aves ameaçadas: dados preliminares para o papagaio-de-cara-roxa, Amazona brasiliensis (Aves: Psittacidae) no Paraná. Arq. Ciênc. Vet. Zool. UNIPAR, Umuarama, v. 18, n. 1, p. 65-69, jan./mar. 2015.RESUMO: Amazona brasiliensis, também conhecido popularmente como papagaio-de-cara-roxa, é uma espécie de Psittacidae endêmica da Mata Atlântica distribuída entre o litoral sul de São Paulo e o litoral Norte de Santa Catarina. Este estudo foi concentrado no estado do Paraná, visando uma prévia caracterização do perfil sanitário natural em filhotes da população por meio de análises microbiológicas. O estudo epidemiológico de uma espécie ameaçada inicia-se com a determinação dos agentes infecciosos comuns na população, que provavelmente co-evoluíram com a espécie e representam baixo risco aos espécimes de vida livre. Do total de colônias isoladas quase 75% foram positivas para a família Enterobacteriaceae. Normalmente, a microbiota entérica de psitacídeos é composta por micro-organismos Gram-positivos, porém a alta porcentagem de Gram-negativas isoladas pode ser explicada pela diferença entre a composição microbiana de adultos e filhotes. Seria interessante um estudo mais detalhado para uma eventual comparação entre possíveis sinais clínicos e micro-organismos presentes em cada indivíduo amostrado. PALAVRAS-CHAVE: Microbiologia. Conservação. Amazona brasiliensis. Litoral do Paraná. USE OF MICROBIOLOGY AS A TOOL FOR THE PRESERVATION OF THREATENED BIRD SPECIES: PRELIMINARY DATA FOR THE RED-TAILED AMAZON, Amazona brasiliensis (Birds: Psittacidae) IN PARANÁABSTRACT: Amazona brasiliensis, also popularly known as Red-tailed Amazon, is an endemic species to the Atlantic Forest. This Psittacidae range goes from the south coast of São Paulo state to the northern coast of Santa Catarina state. This study focuses on the population in the state of Paraná, aiming to perform a preliminary characterization of the prevalence of natural pathogens in nestlings through microbiological analyses. The epidemiological study of an endangered species begins with the determination of common infectious agents within the population, which probably co-evolved with the species and represent a low risk to free-living specimens. Almost 75% of the colonies isolated were positive for Enterobacteriaceae. Usually, the enteric microbiota of psittacidae consists of Gram-positive microorganisms, but the high percentage of isolated Gram-negative bacteria can be explained by differences between the microbial composition of adults and nestlings. It would be interesting to further develop this study into a more detailed comparison between possible clinical signs and microorganisms present in each individual sampled.
