ABSTRACT: The study of fossil and subfossil birds in Brazil is still in its early stages despite its relatively abundant material. The remains are represented by bones, feathers, mummified specimens, eggs, coprolites, pellets, and tracks found in all Regions of the country starting in the 1830s. They are known from the Early Cretaceous to the latest Holocene, albeit several temporal gaps exist, and the most expressive diversity and quantity are concentrated in a few but important sites. Our survey and review of the literature and some previously unpublished specimens resulted in a list of 670 records demonstrating that the country’s known past avifaunas are essentially modern and rely mostly on provisional determination methods. Despite this, 15 extinct genera and 20 extinct species were newly described, demonstrating this field’s potential. The proper study of numerous long-stored materials from both paleontological and archeological contexts and eventual new remains can contribute significantly to our understanding of avian evolution and their taxonomic diversity throughout time, besides furnishing paleobiogeographic and paleoenvironmental information.

ABSTRACT Brazil is home to many mountain ranges which harbor diverse avifauna. However, studies on the altitudinal distribution of Brazilian birds are still few and many have never been published, hampering both the dissemination of basic information and conservation actions. Here we present a critical review of ornithological studies undertaken in Brazilian mountain ranges, and propose a classification of geographic scope, altitudinal gradient, and methodology. Since 1922, 184 ornithological studies included altitude in some way in Brazil, encompassing a variety of research topics and species. About a quarter of these studies were never published in peer-reviewed journals, and 39% do not provide basic data on elevation nor link the bird species with sampling plots, thus limiting their applicability. The majority of studies are concentrated (83%) in southern and southeastern Brazil, especially in the Serra do Mar range, and so most data are associated with the Atlantic Forest. Gaps remain in other regions, such as Amazonia (Pantepui region). Most studies either did not sample the entire elevation gradient, were not standardized, lacked explicit hypothesis, or did not account for a seasonal sampling embracing the four seasons of the year, so interpretation of the observed patterns remains difficult. With this compilation, we organize the available information and point to future altitudinal research on birds, in addition to highlighting the importance of preserving habitats along altitudinal gradients in the mountainous regions in Brazil. avifauna However actions scope gradient methodology 1922 18 peerreviewed peer reviewed journals 39 plots applicability 83% 83 (83% range Forest Pantepui region. region . region) standardized hypothesis year difficult compilation 192 1 3 8 (83 19 (8 (

ABSTRACT Birds’ seasonal altitudinal movements in Brazil are poorly understood. The main source of information and has fostered interest since the 1980s. However, most of the available information is anecdotal, sources are repeatedly cited, and the information provided is quite superficial and speculative. Through bibliographic searches, we found 107 studies, 83 (77%) of which we consider valid, and only 63 (59%) were peer-reviewed. Most studies were carried out in southern and southeastern Brazil. Only 11 studies explicitly addressed seasonal altitudinal movements. Surprisingly, none of the studies simultaneously comprised a full year of study, standardized sampling methods, and encompassed the entire altitudinal range through which the birds might have moved. As a consequence, the quality of the data is questionable, and the expression “altitudinal migration” is unlikely to be accurate and has never been unequivocally demonstrated for birds in Brazil. Mention of “altitudinal migration” was found for 68 bird species, but these must be more clearly defined and appropriately tested.

We present records of chewing lice collected from bird skins of the families Anhimidae, Threskiornithidae, and Aramidae deposited at the Museum of Zoology of University of São Paulo (MZUSP). Twenty-one chewing lice species from the suborders Amblycera and Ischnocera were identified, seven of which are new records for Brazil. These species belong to the genera Ardeicola (1), Colpocephalum (3), Ibidoecus (1), and Plegadiphilus (2). Furthermore, ten species were recorded from new localities in Brazil, and Colpocephalum cayennensisPrice & Emerson, 1967 is for the first time recorded with precise locality in the country. Lastly, the bird host subspecies Phimosus infuscatus nudifrons (Spix, 1825) (Threskiornithidae) was for the first time found to harbor lice species. Anhimidae Threskiornithidae MZUSP. MZUSP .

Abstract The Black Skimmer (Rynchops niger) and the Large-billed Tern (Phaetusa simplex) are two migratory waterbirds that breed simultaneously on many river beaches in South America. Both are polytypic taxa with little information about the distribution and nonbreeding (“wintering”) areas. Based on data from the literature, citizen science websites, fieldwork, and specimens housed in natural history museums, we revised the distribution of some of the main breeding colonies in South America, comparing it with continental rainy cycles to identify generalities about the role of precipitation seasonality on the defining intratropical migration routes of these species. Our data suggest that the seasonal precipitation cycle of South America directly influences the reproductive timing and distribution of both species, which is largely circumscribed by South America’s rivers. After breeding on sandy beaches during the dry season, both species disperse in small groups or even individually - not in large flocks as seen in breeding areas - making it difficult to find general migration patterns during the rainy season. Nonetheless, individuals of both species tend to follow the course of the largest rivers of the continent and even alternative routes to disperse into several areas throughout South America during the nonbreeding season.

Abstract The northeast Brazilian state of Alagoas harbors a rather diverse, and one of the world’s most threatened, avifauna. However, the knowledge about its avifauna is currently scattered on several publications and the state’s birds have never been comprehensively assembled into a checklist. To fill this shortfall, we present here the first critical review of all available bird records for the state of Alagoas. We present a list of 520 bird species recorded in the state, of which 503 are supported by documentary evidence. We also comment on the distribution, migratory movements, taxonomy and conservation of the region’s avifauna and correct previous misidentified or invalid records for the state.

ABSTRACT 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.

ABSTRACT Altitudinal migration in birds comprises seasonal movements between breeding and non-breeding areas in mountainous regions, attributed to biotic and abiotic factors. Different authors have suggested the existence of altitudinal migration between high and low areas of the mountains of the Atlantic Forest, with movement from high to low during the winter when birds would be fleeing the cold and in search of food, but there is no documented evidence. Through recaptures of understory birds, we investigated possible altitudinal migration in a region of the Atlantic Forest in Southeast Brazil. Twenty mist-nets were set at four locations between 15 and 729 m a.s.l. during 143 days of field work, distributed over 54 months and covering all seasons of the year. A total of 1946 birds (98 species) were captured/banded with 558 being recaptured (28.6%; 45 species). However, only 42 of the recaptures were at a different elevation. Most of the movements were of short distances and performed only once by birds, showing no seasonal pattern. These movements may be better interpreted as daily movements undertaken by birds of mixed-species flocks looking for food or moving around their respective home-ranges. Our results show that mist-nets may not be an effective tool in detecting altitudinal movements of birds and that other methods should be evaluated for this purpose.

Abstract Scientific collections constitute a valuable source for contributions to scientific research and the training of human resources in systematics, but also other areas of biological knowledge. In this contribution, we intend to discuss these advancements in collections and the role played by FAPESP in sponsoring them, as well as a general overview of the zoological collections in São Paulo state. We also aim to stress the importance of zoological collections and the need for continuous logistic and financial support from institutions and research agencies to maintain and develop these unique repositories of biodiversity. From 1980 to the present, FAPESP supported 118 research projects focused on several areas of zoology that are directly or indirectly associated with collections. There is a constant growth in the number of projects, and the financial support provided by FAPESP through the Biota Program was paramount for the advancement of our knowledge of biodiversity in Brazil. Parallel to the scientific advances, but not less important, this support allowed curators to increase the number of specimens, and to organize, maintain and digitize them in these valuable and irreplaceable collections. Regarding the lack of new taxonomists, it is essential that FAPESP and universities in São Paulo encourage the formation of new academics in zoological groups where specialists are rare. Considering the investment provided by FAPESP, it is quite important that the institutions that benefited from these resources took greater responsibility to safeguard these collections, and they should consider including resources on their budgets to obtain safety certificates, ensuring their permanence for many generations to come. Zoological collections are a heritage of humanity and are essential not only for the improvement of our knowledge of biodiversity but also with direct applications, among other services provided by these biological resources. It is important that research and teaching institutions in São Paulo that house specimens under their care start to value more this important patrimony and this heritage, as these collections represent the most valuable testimony of our impressive biodiversity, records of our past, and windows to our future, essential to our academic, scientific, cultural and social sovereignty. systematics contribution state 198 present 11 Brazil advances organize taxonomists rare certificates come applications past future academic sovereignty 19 1

Resumo As coleções científicas constituem uma fonte valiosa para contribuições à pesquisa científica e para a formação de recursos humanos em sistemática, mas também em outras áreas do conhecimento biológico. Nesta contribuição, pretendemos discutir esses avanços nas coleções e o papel desempenhado pela FAPESP no seu patrocínio, bem como um panorama geral das coleções zoológicas do estado de São Paulo. Também pretendemos enfatizar a importância das coleções zoológicas e a necessidade de apoio logístico e financeiro contínuo de instituições e agências de pesquisa para manter e desenvolver esses repositórios únicos de biodiversidade. Ao longo de 1980 até os dias atuais, a FAPESP apoiou 118 projetos de pesquisa focados em diversas áreas da zoologia, direta ou indiretamente associados a coleções. Há um crescimento constante no número de projetos, e o apoio financeiro da FAPESP por meio do Programa Biota foi fundamental para o avanço do nosso conhecimento sobre a biodiversidade no Brasil. Paralelamente aos avanços científicos, mas não menos importante, este apoio permitiu aos curadores aumentar o número de exemplares, e organizá-los, mantê-los e digitalizá-los nestas valiosas e insubstituíveis coleções. Em relação à falta de novos taxonomistas, é fundamental que a FAPESP e as universidades paulistas estimulem a formação de novos acadêmicos em grupos zoológicos onde os especialistas são raros. Considerando o investimento realizado pela FAPESP, é de suma importância que as instituições beneficiadas com esses recursos tenham maior responsabilidade na salvaguarda desses acervos, devendo considerar a inclusão de recursos em seus orçamentos para obtenção de certificados de segurança, garantindo sua permanência por muitas gerações. As coleções zoológicas são patrimônio da humanidade, e são essenciais não apenas para o aprimoramento do nosso conhecimento sobre a biodiversidade, mas também com aplicações diretas, entre outros serviços prestados por esses recursos biológicos. É importante que as instituições de pesquisa e ensino paulistas que abrigam exemplares sob seus cuidados passem a valorizar mais esse importante patrimônio e essa herança, pois essas coleções representam o testemunho mais valioso de nossa impressionante biodiversidade, registros do nosso passado e janelas para o nosso futuro, essenciais à nossa soberania acadêmica, científica, cultural e social. sistemática biológico contribuição patrocínio Paulo 198 atuais 11 zoologia Brasil científicos organizálos, organizálos organizá los, los organizá-los mantêlos mantê digitalizálos digitalizá taxonomistas raros acervos segurança gerações humanidade diretas biológicos herança futuro acadêmica social 19 1

Abstract The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

Taxonomy is essential to biological sciences and the priority field to be supported in face of the biodiversity crisis. The industry of scientific publications has made extensive use of bibliometric indexes, resulting in distortions to institutions, organizations, and researchers, such as the side effect known as Journal Impact Factor (JIF) mania. Inadequacies of the most widely used bibliometric indexes from giant companies Clarivate™ (InCites™) and RELX™ Elsevier B.V. (Scopus®) to assessment of the relevance of taxonomic publications were considered as one of the impediments for the progress of this field. Recently, Clarivate suppressed the mega-journal Zootaxa, focused on taxonomy, from Journal Citation Reports (JCR), a database with 12,000 periodicals. Zootaxa suppression, together with other 32 journals, was based on an unusual high proportion of self-citations. Suppressed journals would thus not receive a value of JIF for 2020. A prompt reaction from the scientific community against the suppression of Zootaxa took place and, accordingly, Clarivate announced its reinstatement. This situation exposed many persistent myths and misuses of bibliometric indexes. The goal of this study is to shed light on the impacts of bibliometric indexes to the taxonomic field and on underlying aspects of the suppression of Zootaxa. Our major question is whether the suppression of any journal from JIF can really affect the production in the taxonomic field. We explored data metrics from the JCR (Web of Science Core Collection™) for 2010–2018 of the top ten zoological journals (eight are included in JCR) in the number of new taxa and journals focused on or regularly publishing taxonomic studies, totaling 123 journals. Zootaxa shows higher levels of self-citations than similar journals. We consider that two possible explanations provided for the high number of self-citations, i.e., Zootaxa’s scope on taxonomy and the fact that it is a mega-journal, are inadequate. Instead, putative explanations are related to the “Zootaxa phenomenon,” a sociological bias that includes visibility, and potential harmful myths that portray Zootaxa as the unique journal that publishes taxonomic studies with an inviting JIF value. Menaces to taxonomy as a science come from many sources and the low bibliometric values of its journals are only one of the factors that contribute for establishing the so-called taxonomic impediment. We suggest rejection of bibliometric indexes, including JIF, instead of considering them when convenient. Taxonomists as a community, instead of being deeply focused on journal metrics endorsing the villainy of bibliometric policies imposed by dominant companies, should be engaged with renewed strength in actions directly connected to the development and promotion of this science.

Abstract The Little Chachalaca (Ortalis motmot) is a widely distributed species in the Amazon basin, typically found in riverine habitats. There are two disjunct populations: the northern O. m. motmot and the southern O. m. ruficeps (known as Chestnut-headed Chachalaca). Here we performed a vocal, morphological and plumage comparison between these two taxa. Birds present differences in tail coloration but are otherwise undiagnosable in terms of plumage. Ortalis m. ruficeps is, however, markedly smaller and lighter than O. m. motmot, with no overlap in size or weight. We also found vocal differences between O. m. motmot and O. m. ruficeps, no overlap in geographic distributions and no signs of hybridization across its range. Based on the available data, Ortalis m. ruficeps thus must be considered a valid species, endemic to Brazil.

Abstract Montane and submontane forest patches in the state of Bahia, Brazil, are among the few large and preserved Atlantic Forests remnants. They are strongholds of an almost complete elevational gradient, which harbor both lowland and highland bird taxa. Despite being considered a biodiversity hotspot, few ornithologists have surveyed these forests, especially along elevational gradients. Here we compile bird records acquired from systematic surveys and random observations carried out since the 1980s in a 7,500 ha private protected area: Serra Bonita private reserve. We recorded 368 species, of which 143 are Atlantic Forest endemic taxa. Some 16 and 13 species are threatened at the global and national levels, respectively. If one accounts for subspecies, the number of Brazilian threatened taxa raises to 21. Species composition differs between lower and higher elevations, in which case lowlands harbor Amazonia-related taxa, whereas highlands are the home of Atlantic Forest-related taxa.

Abstract The White-collared Kite (Leptodon forbesi) is an endemic and threatened raptor of the Brazilian Atlantic Forest. Here we present the known records of the species, describe the vegetation types where it was found and show Ecological Niche Models generated using Maxent algorithm. Most of the presence data were recorded in open ombrophilous forest and seasonal semideciduous forest in the states of Alagoas and Pernambuco. Maxent model had a good performance (AUC = 0.982 ± 0.004 SD), showing higher suitability for the species from Paraíba to Alagoas states. Maxent average model revealed a distribution range of 20,344 km² and an area of occupancy of 1,636.89 km². The most suitable areas for the species are those near watercourses and streams. We suggest the creation of protected areas, including private ones, and possible restoration actions to connect the most suitable forest fragments, along with the captive breeding, as the most appropriate strategies for the conservation of the White-collared Kite.

Abstract The Belem Curassow (Crax fasciolata pinima) is one of the most endangered birds in South America, without sightings of birds in the wild for 40 years. This subspecies is nationally and internationally classified as critically endangered and close to extinction, suffering from poaching and deforestation in its range. Here we present new records of free-living individuals made on three indigenous lands in Pará and Maranhão states: in part of Terra Indígena Mãe Maria, Bom Jesus do Tocantins, Pará; in locations within the Reserva Biológica do Gurupi/Terra Indígena Alto Turiaçu, Centro Novo do Maranhão, Maranhão; and around the Terra Indígena Rio Pindaré, Alto Alegre do Pindaré, Maranhão. We also provide recommendations to protect this bird via a dedicated conservation program which includes finding new individuals in non-sampled areas (north of BR-222), estimating population size, enhancing taxonomic and natural history knowledge, capturing wild animals in order to start urgent ex situ conservation programs, and developing environmental awareness programs with the local and indigenous populations.
