Global movement patterns of migratory birds illustrate their fascinating physical and
physiological abilities to cross continents and oceans. During their voyages, most birds land …

This paper presents a comprehensive review and analysis of the available literature and
information on droughts to build a continental, regional and country level perspective on …

The green-up of vegetation in spring brings a pulse of food resources that many animals
track during migration. However, green-up phenology is changing with climate change …

As climate change transforms the biosphere, more comprehensive and biologically relevant
measurements of changing conditions are needed. Traditional climate measurements are …

There is compelling evidence that A fro‐P alaearctic (A‐P) migrant bird populations have
declined in E urope in recent decades, often to a greater degree than resident or short …

Migratory birds track seasonal resources across and between continents. We propose a
general strategy of tracking the broad seasonal abundance of resources throughout the …

In 2007, the first miniature light-level geolocators were deployed on small landbirds,
revolutionizing the study of migration. In this paper, we review studies that have used …

Migratory species are in rapid decline globally. Although most mortality in long-distance
migrant birds is thought to occur during migration, evidence of conditions on migration …

Migratory birds that experience poor overwintering conditions are often late to arrive at the
breeding grounds, which is known to depress individual fitness. Despite the importance of …

Light‐level geolocation data loggers, or geologgers, have recently been miniaturized to the
extent that they can be deployed on small songbirds, allowing us to determine many …
