History Of

Seed-finches are small-sized Neotropical granivorous birds characterized by extremely strong and thick beaks. Among these birds, the Great-billed Seed-Finch Sporophila maximiliani has been selectively and intensively trapped to the extent that has become one of the most endangered bird species in South America, yet its taxonomy remains complex and controversial. Two subspecies have been recognized: S. m. maximiliani (Cabanis, 1851), mainly from the Cerrado of central South America, and S. m. parkesi Olson (= Oryzoborus m. magnirostris), from northeastern South America. Originally, S. m. parkesi was diagnosed as being larger than the Large-billed Seed-Finch, S. c. crassirostris (Gmelin, 1789), but proper comparisons with S. m. maximiliani, which is larger than S. c. crassirostris, were never performed. Here we provide a review of the taxonomic and nomenclatural history of S. maximiliani, reevaluate the validity and taxonomic status of the subspecies based on morphological characters, and significantly revise its geographic distribution. Analyses based on plumage patterns and a Principal Component Analysis of morphometric characters indicated that S. m. parkesi is most appropriately treated as a synonym of the nominate taxon, which results in a monotypic S. maximiliani comprising two disjunct populations. Further, we conducted systematic searches for S. maximiliani in Brazil, in an attempt to obtain natural history information. After more than 6,000 hours of fieldwork in 45 areas of potential and historical occurrence, S. maximiliani was located only in two sites, in marshy environments called veredas, confirming the critical conservation status of this species, at least in Brazil. We discuss the conservation potential for, and the problems involved with, captive breeding of S. maximiliani for reintroduction into the wild.

Previously known from two specimens, Kaempfer's Tody-tyrant Hemitriccus kaempferi is a globally threatened species endemic to the southern Brazil Atlantic Forest. The first field observations of this little-known taxon were made in the 1990s and our data therefore provide the first published information on its natural history, including breeding biology, behaviour and vocalizations, as well as a new locality. As very little information has appeared in the literature concerning the identification of this species, we present notes on its plumage and habits. Remarks concerning the species's conservation prospects and the importance of the remaining forest in the vicinity of the type-locality for other threatened bird species are made.

We present a review on the principal interactions between birds and termites in Brazil. We found 218 bird species feeding on termites or using termitaria for nesting or perching. Termites were mentioned as food source for 179 bird species. Alates were the most consumed caste. Termitaria were mentioned as nest site for 45 bird species. Some bird species also perch on the top of termite mounds to search for their prey or to conduct territorial and/or courtship displays. Considering all interactions between both animal groups, little is known about the identification of termite genera or species. Therefore, we suggest more detailed studies to be conducted on the natural history and ecology of interactions between birds and termites in Brazil.

The 19Th Century

The exhibition of two mummies in the Natural History cabinet in Paris aroused the interest of various scientific expeditions that made a stopover in Tenerife in the first half of the 19th century. Nicolas Baudin’s expedition in 1800 coincided with the discovery of a cave with mummies in El Sauzal and three ended up in the university museums of Montpellier and Göttingen and one in the cabinet of Saviñón. Another mummy was given to von Krusenstern’s Russian expedition of 1803, currently in the museum of Saint Petersburg. A new cave with mummies was discovered ca. 1815 in Tacoronte, which ended up in the scientific cabinet of Megliorini. Another mummy located in Valleseco, Santa Cruz, around 1823, was sold in Puerto de la Cruz to a Swiss merchant for the Geneva museum.

At least nine bird species were described as new to science on the basis of material collected by Eduard Eversmann and Christian Pander during a Russian embassy headed by Aleksandr Negri to Bukhara in 1820–1821. We identified the type specimens and determined the type localities of these species, which are currently housed in natural history museums of Berlin, Germany, and Moskva, Russia. We suggest that, if only two subspecies of Otus brucei are recognized, the larger northern migratory one should be recognized as O. b. brucei (Hume, 1872), and the smaller southern nonmigratory one as O. b. semenowi (Zarudnyj & Härms, 1902), and we show that the name semenowi has been misapplied to the population from the Tarim Basin. We designate a lectotype for the nominal species Scops obsoleta Cabanis.

Abstract Interdisciplinary scholarship that combines research questions and methodologies from biology and ethnohistory generates new insights into historical interactions between human and bird populations in ancient and colonial Mesoamerica. Codices, ethnohistorical sources, and surviving feather art point to the religious, economic, and artistic importance of various types of birds to Nahua people. Alongside the well-known resplendent quetzal and lovely cotinga, many additional species were significant to ancient and colonial Nahuas. This article presents potential directions for scholarship that bridge biology and ethnohistory and surveys key resources, including natural history collections and online databases. Finally, the article employs the biological literature to describe eleven bird species of great importance to Nahuas, detailing the species’ appearance and plumage, geographic range, variation, habitat, behaviors, and current status. Ultimately, the article demonstrates how insights from natural history and ethnohistory together allow for a fuller understanding of Nahuas’ material and conceptual interactions with these birds.

SummaryWe documented the consequences of large-scale habitat loss on a community of Galápagos native bird species on San Cristóbal island, based on point counts conducted between 2010 and 2017. Surprisingly, despite considerable habitat change and a variety of other threats, the landbirds of San Cristóbal have fared much better than on the neighbouring islands Floreana or Santa Cruz. While two species went extinct very soon after human colonisation, the majority have adapted well to subsequent vegetation change and habitat loss. The endemic San Cristóbal Mockingbird Mimus melanotis is more widespread than previously thought and its population seems to be stable since the 1980s. We thus propose a change in IUCN classification from ‘Endangered’ to ‘Near threatened’. We present evidence gained by interviewing locals which suggests that a small population of the Least Vermilion Flycatcher Pyrocephalus dubius, classified as ‘Extinct’ by BirdLife International, may have persisted until very recently. Although extensive searches in 2018 and 2019 were unsuccessful, the possibility remains that a few birds may have survived in remote parts of the island. Further searches that involve the general public and other interested parties are therefore deemed necessary.

Abstract Bird fossils from the Late Pleistocene locality Binagada, deposited kept in the National Museum of Natural History in Kyiv (Ukraine), are described in this paper. Twenty six bird species are identified, including five (Little Stint, Great snipe, Jack snipe, White-winged lark and Rosy Starling) which have not been previously known from this locality. The validity of extinct species Calidris binagadensis (Serebrovsky, 1940) is confirmed and the invalidity of subspecies Anas platyrhynchos paleoboschas Serebrovsky, 1940 is shown. The finding of Rosy Starling fossils in Transcaucasian region confirms the range reduction of this species at the end of Pleistocene.

Reduced Impact Logging

As part of a larger study of reduced-impact logging effects on bird community composition, we surveyed birds from December to February during the 2003-2004 wet-season within harvested and unharvested blocks of the La Chonta forestry concession, Department of Santa Cruz, Bolivia. The logged forest was harvested using reducedimpact logging techniques between one and four years previously. During point count surveys, we identified 5062 individual birds, belonging to 155 species, and 33 families. We provide a list of bird species found within the harvested and unharvested blocks of the concession for the benefit of other researchers assessing the responses of Neotropical avifauna to disturbance, and to facilitate increased understanding of the diverse bird assemblages found within the lowland subtropical humid forests of Bolivia.
