Our understanding of migratory birds' year‐round ecology and evolution remains patchy
despite recent fundamental advances. Periodic reviews focus future research and inform …

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 …

Abstract We open this Special Feature on stable isotopes in mammalian research with a
beginner's guide, an introduction to the novice and a refresher to the well-versed. In this …

Migratory bird needs must be met during four phases of the year: breeding season, fall
migration, wintering, and spring migration; thus, management may be needed during all four …

Conservation of migratory animals requires information about seasonal survival rates.
Identifying factors that limit populations, and the portions of the annual cycle in which they …

Estimation of demographic parameters is central to research questions in wildlife
management, conservation, and evolutionary ecology. I review the 7 major classes of mark …

As tropical forests are cleared, a greater proportion of migratory songbirds are forced to
winter in agricultural and disturbed habitats, which, if poorer in quality than natural forests …

The hypothesis that migratory bird populations are limited during the non-breeding season
is increasingly supported by empirical studies that also suggest consequences that carry …

F, researchers interested in factors that influence the fitness of migratory birds have realized
that events occurring at times and locations outside the breeding season can influence …

The recent application of stable‐isotope analyses, particularly the use of stable‐hydrogen‐
isotope (δD) measurements of animal tissues, has greatly improved our ability to infer …
