Flycatchers in the genus Empidonax are among the most difficult avian taxonomic groups to identify to species. Observers often rely on calls or songs in the field or detailed morphometrics in the hand to identify species. In January and February[...]

The use of light-level geolocators for monitoring migration has been limited to non-cavity roosting species because light transitions for cavity-roosting species are obscured. Using Northern Flickers (Colaptes auratus), nocturnal cavity-roosting[...]

Undulated Antshrikes (Frederickena unduliger) inhabit dense lowland humid forest understory and, as with other species of antbirds, many aspects of their behavior and ecology are poorly known, especially their breeding biology. We provide the fi[...]

White sand terra firme forests are unusual ecosystems scattered across Amazonia, covering just 3% of the basin. These forests differ from surrounding forests in their scleromorphic vegetation, low nutrient content, and propensity to harbor endem[...]

Development of new methods for obtaining basic demographic data from difficult-to-access breeding colonies and easily disturbed species is an important challenge in studies of seabirds. We describe a method that can generate data concerning annu[...]

All air-breathing organisms must face the challenge of oxidative damage, and understanding how animals cope can lend insight into their ecology. Unlike other vertebrates, birds rely primarily on fats to fuel endurance exercise such as migration,[...]
