    Title translation Nidos, huevos y evidencia reproductiva del metalura tiria (Metallura tyrianthina) y el calzadito reluciente (Eriocnemis vestita) en el noreste de los Andes colombianos
    Abstract The reproductive biology of tropical hummingbirds has been documented and studied in only a small fraction of species relative to the great diversity of this group. Little has been written about breeding biology of hummingbirds at the Northern Andes Eastern Cordillera in Colombia. We present detailed information on the dates, nesting locations, construction materials, measurements of nests and eggs, and gonad development of adult specimens to augment the scant reproductive data available of 2 widely distributed highland hummingbirds, the Tyrian Metaltail (Metallura tyrianthina) and the Glowing Puffleg (Eriocnemis vestita). These data were obtained during multi-taxa collection expeditions in the high-elevation region of the Department of Boyacá, Colombia. We found 2 Tyrian Metaltail nests in February and May, and adults with enlarged gonads in August. The single Glowing Puffleg nest was found in October, adults with enlarged gonads in May and October, and a chick mortality event (possibly due to frost) in November. Nesting sites for both species were in banks where they built 2-layered cup nests. Although nest locations and construction materials were similar to what has been reported before for hummingbirds in these genera, we identified the plants of these nests' microhabitats, as well as the families and genera of liverworts, mosses, and others used as nest construction materials. The evidence of active nests and enlarged gonads of specimens collected in this study, together with observations made by previous authors, suggest that these 2 hummingbird species breed throughout most of the year at the northeastern Andes. Our data contributes to the understanding of the reproductive biology of these hummingbirds in this region.

    Abstract Digital bioacoustic collections preserve important behavioural and ecological traits, as well as trackable evidence of the presence of species in space and time. Well-structured and open-source repositories provide valuable information for science and biodiversity conservation. Here, we introduce the Environmental Sound Collection – ‘Mauricio Álvarez-Rebolledo’ (Colección de Sonidos Ambientales IAvH-CSA) at Instituto Humboldt in Colombia, which is one of the most relevant natural sound repositories in South America. The collection was founded in 1998 as ‘Banco de Sonidos Animales (BSA)’ to document Colombian biodiversity and guide conservation actions, two aims that remain at the forefront of our daily work. After over 25 years, the collection has preserved more than 25,000 audio specimens from over 1,300 species. Here, we highlight the value of sound collections by presenting a historical overview of our collection and providing examples of its role in research and outreach. We also identify taxonomic and geographical gaps that need to be filled, analyse the impact of new technological advances on sound collections, and discuss the critical role of acoustics in the future of research and biodiversity conservation programmes.

    Abstract The continuous assessment of endemic and near-endemic species is an important and complementary tool to identify and determines conservation priorities and responsibilities for a country. We reappraised the Colombian endemic and near-endemic bird list by Stiles (1998). The new lists, was based on an extensive literature survey, field observations and ornithological records for the country. Of the 1639 resident species, 79 were classified as endemics, 193 as near-endemics, including five species restricted to islands, 19 species classified as of interest since they have nearly 50% of their geographical distribution in Colombia, while 16 species are data deficient to determine their status. Highest concentrations of species are found at medium elevations in mountains (800-2400 m.a.s.l.), with the Sierra Nevada de Santa Marta, Pacific geographic region and Eastern Cordillera having the highest proportion of species. Of the near-endemics, most of them are shared with Ecuador and Panama at the Pacific side. Recent distributional information is needed for several species, as well as studies on natural history, population dynamics and life history traits. It is necessary to contrast our findings with the new threatened species list underway, to further complement extinction risks, assess conservation action plans, and the biological responsibilities we have in Colombia.

    Abstract 1. The acute phase immune response, which includes fever and sickness behaviours, carries high costs in energy and time, but enhances pathogen clearance in diverse hosts. Hypotheses based upon pathogen pressures and life-history trade-offs predict that costly immune responses will decrease in strength as latitude increases. However, whether the acute phase response shows latitudinal patterns among free-living, wild populations remains unknown. 2. Here, we studied fever and sickness behaviours during the early breeding season in free-living song sparrows (Melospiza melodia) along a latitudinal gradient in southern California (CA), Washington (WA), and Alaska (AK). In 2007 and 2008, we injected males with lipopolysaccharide and assessed sickness behaviour by measuring changes in territorial aggression. In 2008, we monitored fever and sickness behaviour in CA and WA birds using a novel telemetric technique: skin-mounted radiotransmitters with temperature sensors. 3. In 2007, territorial defence varied by latitude, with a lower probability of territorial response at 24 h after injection in CA, but not in WA or AK. Radiotelemetry in 2008 revealed that CA birds showed pronounced and prolonged lethargy and fever (c. 2 °C above control males throughout the night), whereas WA birds showed only moderate lethargy and fever (c. 1 °C, returning to control levels during the night). 4. This study establishes radiotelemetry as a powerful method for quantifying fever and sickness behaviours in small, free-living vertebrates. Moreover, our data suggest that latitude predicts the strength of these responses. These results can provide insight into disease susceptibility and spread among wild populations.

    Abstract The birds in the family Parulidae-commonly termed the New World warblers or wood-warblers-are a classic model radiation for studies of ecological and behavioral differentiation. Although the monophyly of a 'core' wood-warbler clade is well established, no phylogenetic hypothesis for this group has included a full sampling of wood-warbler species diversity. We used parsimony, maximum likelihood, and Bayesian methods to reconstruct relationships among all genera and nearly all wood-warbler species, based on a matrix of mitochondrial DNA (5840 nucleotides) and nuclear DNA (6 loci, 4602 nucleotides) characters. The resulting phylogenetic hypotheses provide a highly congruent picture of wood-warbler relationships, and indicate that the traditional generic classification of these birds recognizes many non-monophyletic groups. We recommend a revised taxonomy in which each of 14 genera (Seiurus, Helmitheros, Mniotilta, Limnothlypis, Protonotaria, Parkesia, Vermivora, Oreothlypis, Geothlypis, Setophaga, Myioborus, Cardellina, Basileuterus, Myiothlypis) corresponds to a well-supported clade; these nomenclatural changes also involve subsuming a number of well-known, traditional wood-warbler genera (Catharopeza, Dendroica, Ergaticus, Euthlypis, Leucopeza, Oporornis, Parula, Phaeothlypis, Wilsonia). We provide a summary phylogenetic hypothesis that will be broadly applicable to investigations of the historical biogeography, processes of diversification, and evolution of trait variation in this well studied avian group.
