Populations of migratory birds are usually considered to be limited by conditions in breeding
or wintering areas, but some might be limited by conditions encountered on migration. This …

Migration is a task that implies a route, a goal and a period of time. To achieve this task, it
requires orientation abilities to find the goal and energy to cover the distance. Completing …

This book introduces readers to a set of powerful and extremely flexible modeling
techniques, starting at" square one" and continuing with carefully chosen applications. Some …

From the red grouse to the Ethiopian bush-crow, bird populations around the world can
provide us with vital insights into the effects of climate change on species and ecosystems …

Optimal migration theory predicts that birds minimizing the overall time of migration should
adjust stopover duration with respect to the rate of fuel accumulation. Recent theoretical …

We examine the potential selective importance of predation danger on the evolution of
migration strategies of arctic‐breeding calidrid sandpipers. Adult calidrids truncate parental …

Tracking radar measurements of winds at the flight levels of bird migration during several
migratory seasons in central Europe, southern Israel and the western Mediterranean are …

Large ecological barriers such as oceans and deserts have considerably shaped the
migratory strategies of birds. The ecological barriers posed by the Alps, the Mediterranean …

Plasma lipid metabolites may be useful indicators of mass changes in migratory birds. To
test utility of plasma metabolites in field studies, we examined effects of several extrinsic …

Western sandpipers Calidris mauri on southward migration fly over the Gulf of Alaska to the
Strait of Georgia, British Columbia, where they stop for a few days to replenish reserves …
