This paper advances an hypothesis that the primary adaptive driver of seasonal migration is
maintenance of site fidelity to familiar breeding locations. We argue that seasonal migration …

We reviewed the occurrences and distributional patterns of migratory species of birds in
Brazil. A species was classified as migratory when at least part of its population performs …

Migration, broadly defined as directional movement to take advantage of spatially distributed
resources, is a dramatic behaviour and an important component of many life histories that …

We outline a general scheme for migration that applies across taxa, incorporates the several
varieties of migration, and includes all levels of biological organization, from genes to …

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 …

Animal movement receives widespread attention within ecology and behavior. However,
much research is restricted within isolated sub‐disciplines focusing on single phenomena …

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

Collaborative research by networks of amateurs has had a major role in ornithology and
conservation science and will continue to do so. It has been important in establishing the …

Migratory species are widespread in terrestrial, aquatic and aerial environments, and are
important both ecologically and economically. Since migration is an adaptive response to …

Although the migration ecology of birds breeding in the Neotropics is still poorly studied
relative to that of their counterparts breeding at north-temperate latitudes, studies conducted …
