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

Altitudinal migration is the seasonal altitudinal movement of birds from breeding areas to
non‐breeding or wintering areas at different elevations. Although this type of migration is …

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 …

One of the key questions regarding the underlying mechanisms of mammalian land
migrations is how animals select where to go. Most studies assume perception of resources …

A topic of recurring interest in ecological research is the degree to which vegetation structure
