Ecologically relevant traits of organisms in an assemblage determine an ecosystem's functional fingerprint (i.e., the shape, size, and position of multidimensional trait space). Quantifying changes in functional fingerprints can therefore provide information about the effects of diversity loss or gain through time on ecosystem condition and is a pr...
Temporal variation in the connectivity of populations of migratory animals has not been widely documented, despite having important repercussions for population ecology and conservation. Because the long-distance movements of migratory animals link ecologically distinct and geographically distant areas of the world, changes in the abundance and mig...
Neotropical countries receive financing and effort from temperate nations to aid the conservation of migratory species that move between temperate and tropical regions. If allocated strategically, these resources could simultaneously contribute to other conservation initiatives. In this study, we use novel distribution maps to show how those resour...
La población del Guardacaminos norteño (Chordeiles minor) ha disminuido más del 60% en los últimos 50 años. Aunque su ecología en Norte América es relativamente bien conocida, es insuficiente la información respecto a la porción de su ciclo de vida no reproductivo y de permanencia en el Neotrópico, particularmente sobre rutas de migración, sitios d...

Presentamos una actualización de la lista de las aves de Colombia con base en registros documentados a partir de septiembre de 2017, siguiendo, por primera vez, criterios estandarizados por el Comité Colombiano de Registros Ornitológicos (CCRO) de la Asociación Colombiana de Ornitología. La lista asciende de 1909 a 1966 especies para el territorio...
The Altillanura is a unique ecosystem within the Colombian Llanos, characterized by well-drained savannas and extensive riparian forests. The Altillanura harbors a rich assemblage of species, largely understudied and currently under threat by large-scale and unplanned agribusiness. Moreover, the number of public protected areas in the Colombian Lla...
Protecting biodiversity while sustaining agricultural production is one of our greatest modern challenges. The dominant conservation paradigm in tropical coffee-growing regions involves land-sharing, wherein wildlife-friendly shade trees are integrated into plantations. Meanwhile, the value of land-sparing approaches that combine intensified farmin...
Gustavo Kattan fue un científico visionario que soñó con repetir expediciones ornitológicas en las localidades históricas del Museo Americano de Historia Natural en Colombia, para estudiar los cambios en las aves del país como respuesta a cambios ambientales y en el paisaje, y así contribuir a su conservación. Construyendo sobre el trabajo de Gusta...
Ecologically relevant traits of organisms inhabiting an ecosystem determine its functional fingerprint. Quantifying changes in the shape, volume and shifts in the position of functional fingerprints can provide information about the effects of diversity loss or gain through time, and is a promising means to monitor ecological integrity. This, howev...
The effect of habitat choice on fuelling behaviour and the organization of migration in birds has rarely been examined, despite the potential impact of widespread anthropogenic transformation of stopover regions. High energetic requirements in migrating birds mean that resource abundance, through its influence on fuel deposition rates (FDR), is exp...
Geographic convergence during migration influences the extent to which animal populations may experience carry‐over effects across periods of the annual cycle. When most individuals of a population share geographic areas during a given period, carry‐over effects are likely stronger than when individuals occupy multiple areas. We used genetic data a...

The role of migratory birds in the spread of parasites is poorly known, in part because migratory strategies and behaviours potentially affecting transmission are not easy to study. We investigated the dynamics of infection by blood parasites through the annual cycle of a long‐distance Nearctic–Neotropical migratory songbird to examine the role...
Tools to study seasonal changes in animal diets are needed to address a wide range of ecological questions. This is especially true of migratory animals that experience distinct environments where diets may be substantially different. However, tracking diets of individuals that move vast distances has proven difficult. Compound-specific isotope ana...
Nearly 300 species of landbirds, whose populations total billions, migrate between the Neotropics and North America. Many migratory populations are in steep decline, and migration is often identified as the greatest source of annual mortality. Identifying birds’ needs on migration is therefore central to designing conservation actions for Nearctic-...
Long-distance migratory organisms are under strong selection to migrate quickly. Stopovers demand more time than flying and are used by individuals to refuel during migration, but the effect of fuel loads (fat) acquired at stopover sites on the subsequent pace of migration has not been quantified. We studied stopover behaviour of Grey-cheeked Thrus...
Long-distance migratory birds are declining globally and migration has been identified as the primary source of mortality in this group. Despite this, our lack of knowledge of habitat use and quality at stopovers, i.e., sites where the energy for migration is accumulated, remains a barrier to designing appropriate conservation measures, especially...
Differences in life-history traits between tropical and temperate lineages are often attributed to differences in their climatic niche dynamics. For example, the more frequent appearance of migratory behaviour in temperate-breeding species than in species originally breeding in the tropics is believed to have resulted partly from tropical climatic...
The significant role that agricultural lands play in the conservation of global biodiversity is increasingly being recognized. Migratory birds, with their wide distributions, high mobility and ability to track variable resources, are common in many agri-cultural habitats. Although presence alone does not guarantee that agroecosystems provide the sa...
The Santa Marta Foliage-gleaner
Automolus rufipectus
is one of 19 endemic bird species found in the Sierra Nevada de Santa Marta (SNSM) in northern Colombia but until recently it was considered a sub-species of the Ruddy Foliage-gleaner
Automolus rubiginosus
. Consequently, published information on its distribution and ecology is lacking, and while...
The Sierra Nevada de Santa Marta in northern Colombia has been identified as a critical spring stopover
site for at least one Neotropical migratory bird species prior to crossing the Caribbean sea on migration. The strategic location of the Sierra suggests that other South American wintering migrants may stopover there, but no information is availa...

Northern South America is a geographic bottleneck that may be limiting the survival of Nearctic–Neotropic migrants. However, very little is known about the migration ecology of transcontinental migrants wintering in South America. We studied the fall migratory strategies of three species of thrush (Catharus ustulatus, C. fuscescens, and C. minimus)...
The Darién region of north-west Colombia marks the end of the Mesoamerican landmass, an
ever narrowing corridor of land that connects North and South America and acts as a major flyway for
birds migrating between the two continents. Despite its strategic location, at the gateway to South America
and at one of the corridors’ narrowest points, there...
Migratory routes and stopover sites used by migrant landbirds may vary among seasons and years. Understanding the degree of such variation is an important aspect of migrant ecology, especially in South America, where routes and sites are not well known. We studied stopover site use by two Vireo species and three Catharus species in the Sierra Nevad...

Stopover sites used to accumulate the energy that fuels migration, especially those used prior to crossing ecological barriers, are regarded as critically important for the survival of Nearctic−Neotropical migratory birds. To assess whether South American stopover sites are used to store the energy required to cross the Caribbean Sea and the Gulf o...
Migration is a highly energy-demanding process, and migratory birds store energy at stopover sites along their migration routes to meet these demands. The Veery (Catharus fuscescens) performs one of the longest migrations of all Neotropical migratory landbirds, yet the stopover sites that it uses and their relative importance to migratory success a...

El resultado de la muda se ve reflejado en el estado y características del plumaje, las cuales a su vez son útiles para la datación y el sexado de aves en la mano. A pesar de la indiscutible utilidad de esta herramienta para la investigación, en el Neotrópico aún carecemos de información detallada sobre la muda de muchas especies. Entre el 2007 y e...
In order to contribute to our knowledge of molt in Neotropical birds, we describe molt strategies, molt cycles and plumage sequences in Diglossa albilatera. Through the examination of captured individuals and museum specimens, we found that, as in other Neotropical species, D. albilatera shows a complex-basic strategy with a pre–juvenile and a part...
Research on Nearctic-Neotropical migratory birds in Colombia has strengthened in the last decade although most work has been centered on boreal migrants. Achievements are reflected in recent publications, in the studies presented at national ornithology conferences, and in the publication of the National Plan for Conservation of Migratory Species....

Establishing migratory connectivity between migratory birds' breeding, wintering, and stopover sites is an important component of their effective conservation and management. For neotropical migrants, geographic origins and migration patterns have been poorly documented. During fall migration of 2009, we identified geographic origins of the Veery (...
Migration represents one of the most vulnerable stages of a migrant's life cycle, but the strategies and stopover sites used by Neotropical migrants in Central America are not well known. We carried out constant-effort mist netting and conducted censuses along transects during one autumn (2007) and one spring (2008) migration in northeast Belize. W...
We studied species occurrence and stopover behavior in Empidonax flycatchers during fall and spring migration in northeast Belize. We recorded 173 individuals of five species of Empidonax flycatcher during fall migration but just one individual during spring migration, suggesting that spring migration routes for the majority of species do not pass...
Timing of breeding is a basic trait that should be understood to determine species' requirements during a crucial stage of their life cycle, especially if conservation measures are needed. This is the case of the San Andrés Vireo (Vireo caribaeus), a vulnerable insectivorous bird endemic to San Andrés Island, Colombia. We explored the relative impo...
To ensure adequate protection of nonbreeding habitats used by Neotropical migratory landbirds, we must first address questions about habitat use and quality. On the Yucatan peninsula, migrants use many habitats, several of which remain unstudied, and methodological differences preclude interhabitat comparisons based on studies to date. We used dist...
We describe the breeding phenology and nesting habitat characteristics of San Andres Vireo Vireo caribaeus for the breeding season of 2004. Nest monitoring of colour marked individuals took place in three major vegetation types (dry scrubland, mangrove forest and dense forest) on San Andr's Island, Colombia. In all of them, vegetation structure var...

Travelling thousands of kilometers every year, the Yellow-billed Cuckoo is a true globe trotter. Its epic migration takes it from its breeding grounds in North America’s deciduous forest, across the Caribbean and the Amazon basin, and deep into South America – and back again! In this phase of the Neotropical Flyways Project we will answer the big unanswered question, how?: https://experiment.com/projects/the-rain-crow-mystery-cuckoos-on-migration-in-colombia
Could anyone recomend a place that can carry out sequencing of PCR products obtained from fecal samples, to carry out metabarcoding? The objective is to describe the diet of a bird species. Thanks!
