Endogenous programs that regulate annual cycles have been shown for many taxa,
including protists, arthropods, fish, mammals and birds. In migration biology, these programs …

The global long‐term decline of migrant birds represents an important and challenging issue
for conservation scientists and practitioners. This review draws together recent research …

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

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 …

Technological innovations have led to exciting fast-moving developments in science. Today,
we are living in a technology-driven era of biological discovery. Consequently, tracking …

Migratory birds regularly perform impressive long-distance flights, which are timed relative to
the anticipated environmental resources at destination areas that can be several thousand …

Birds migrate over vast distances at substantial costs. The highly dynamic nature of the air
makes the selection of the best travel route difficult. We investigated to what extent migratory …

Aim Avian migration strategies balance the costs and benefits of annual movements
between breeding and wintering grounds. If similar constraints affect a large numbers of …

Understanding what drives or prevents long‐distance migrants to respond to environmental
change requires basic knowledge about the wintering and breeding grounds, and the timing …

Dispersal is one of the key processes in sha** distributional ranges and community
assemblages, but we know little about animal dispersal at the individual, population, or …
