Conservation efforts are most effective when we have complete demographic information for
a species of concern. Nevertheless, fundamental gaps in our knowledge of demography still …

Why and how new migration routes emerge remain fundamental questions in ecology,
particularly in the context of current global changes. In its early stages, when few individuals …

With many of the world's migratory bird populations in alarming decline, broad‐scale
assessments of responses to migratory hazards may prove crucial to successful …

For migrating land birds, the influence of extrinsic factors (eg, weather and energetic
condition) on stopover site selection relative to factors intrinsic to habitat (eg, food) may be …

We estimated fat load, length of stopover, and rate of mass change for six Neotropical
migrant landbird species at a site along the northern coast of the Gulf of Mexico. Swainson's …

Adolph, SC, and J. Roughgarden. 1983. Foraging by passerine birds and Anolis lizards on
St. Eustatius (Netherlands Antilles): implications for interclass competition and prédation …

This study examined the autumnal stopover patterns of migratory passerines on Appledore
Island, Maine, from 1983 to 1992. We recaptured 13.4% of migratory passerines at least one …

We evaluated whether fruit selection by autumn-migrating birds at an important stopover site
in southern New England was related to water-soluble antioxidant content of fruits. We …

Background Change in behavior is one of the earliest responses to variation in habitat
suitability. It is therefore important to understand the conditions that promote different …

Background Migratory connectivity links the different populations across the full cycle and
across the species range and may lead to differences in survival among populations …
