In most long‐distance migratory birds, juveniles migrate without their parents and so are
likely to lack detailed knowledge of where to go. This suggests the potential for stochasticity …

Nearly 300 species of landbirds, whose populations total billions, migrate between the
Neotropics and North America. Many migratory populations are in steep decline, and …

Recovery from infection is not always complete, and mild chronic infection may persist.
Although the direct costs of such infections are apparently small, the potential for any long …

Estimating how much long‐distance migrant populations spread out and mix during the non‐
breeding season (migratory connectivity) is essential for understanding and predicting …

Aim Global declines in the populations of migratory species have been attributed largely to
climate change and anthropogenic habitat change. However, the relative contribution of …

The rise of antibiotic resistance demands the acceleration of molecular diversification
strategies to inspire new chemical entities for antibiotic medicines. We report here on the …

Currently, the deployment of tracking devices is one of the most frequently used approaches
to study movement ecology of birds. Recent miniaturization of light‐level geolocators …

Many tropical habitats experience pronounced dry seasons, during which arthropod food
availability declines, potentially limiting resident and migratory animal populations. In …

Over decades it has been unclear how individual migratory songbirds cross large ecological
barriers such as seas or deserts. By deploying light-level geolocators on four songbird …

Properly timed spring migration enhances reproduction and survival. Climate change
requires organisms to respond to changes such as advanced spring phenology. Pied …
