Refueling performance is the primary currency of a successful migration as birds must maintain energy stores to achieve an optimal travel schedule. Migrating birds can anticipate heightened energy demand, not to mention increased uncertainty that energy ...

Many shorebirds are long-distance migrants and depend on the energy gained at stopover sites to complete migration. Competing hypotheses have described strategies used by migrating birds; the energy-selection hypothesis predicts that shorebirds attempt ...

Combined use of radar and mist net trapping to detect species composition of nocturnal migrants
The Strait of Messina, in southern Italy, is a well-known migration hotspot for diurnal migrants such as raptors. Radar studies have also shown that there is a considerable rate of nocturnal passage of migrants during spring migration. During the spring

Avian Haemosporidian blood parasite infections at a migration hotspot in Eilat, Israel [PDF]
Haemosporidian blood parasites are frequent amongst passerines. Though they often do not cause detectable consequences to host health, however, their presence or absence and also their prevalence across host populations may potentially carry ...

Spring migration of Ruffs Philomachus pugnax in Fryslân: estimates of staging duration using resighting data [PDF]
Seasonal bird migration involves long flights, but most time is actually spent at intermediate staging areas. The duration of stay at these sites can be evaluated with mark–recapture methods that employ day-to-day local encounters of individually marked ...

To successfully perform their long‐distance migrations, migratory birds require sites along their migratory routes to rest and refuel. Monitoring the use of so‐called stopover and staging sites provides insights into (a) the timing of migration and (b ...

Migration stopover ecology of Cinnamon Teal in western North America
Identifying migration routes and fall stopover sites of Cinnamon Teal (Spatula cyanoptera septentrionalium) can provide a spatial guide to management and conservation efforts, and address vulnerabilities in wetland networks that support migratory ...
