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

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 …

It has been suggested that birds migrate faster in spring than in autumn because of
competition for arrival order at breeding grounds and environmental factors such as …

Avian fat storage is associated with both benefits and costs. Although the benefits of
maintaining higher energetic reserves have long been considered, the associated costs …

Animals process sensory information according to specific computational rules and,
subsequently, form representations of their environments that form the basis for decisions …

Approximately two thirds of migratory songbirds in eastern North America negotiate the Gulf
of Mexico (GOM), where inclement weather coupled with no refueling or resting …

Bird migration routes often follow detours where passages across ecological barriers are
reduced in extent. This occurs in spite of the fact that long barrier crossings are within the …

Local concentrations of migrating, fat-depleted birds with similar diets can lead to increased
competition for food at a time when energy demand is high. Results of a predator-exclosure …

Movement, from foraging to migration, is known to be under the influence of the
environment. The translation of environmental cues to individual movement decision making …

Many species of Nearctic landbirds exhibit behavioral plasticity during migration,
presumably to compensate for energetic demands of migratory flight. At Block Island, Rhode …
