disentangling these from the dependencies between migratory stages is fundamental to …

For an avian migrant, refueling capacity attainable during stopovers governs the entire
migration schedule and, ultimately, its fitness. Specifically, timely replenishing energy stores …

Highlights•We examined whether departure timing affects barn swallows' pace of autumn
migration.•Daily flight speeds during migration were unrelated to departure timing.•Late …

Peregrine falcons (Falco peregrinus) have undergone a steady hemisphere-wide recovery
since the ban on DDT in 1973, resulting in an ongoing increase in the level of danger posed …

Migratory strategies dictate stopover ecology, particularly concerning decisions of when,
where and how long to stop, and what to do at stationary periods. In birds, individuals stop …

Many long-distance migratory birds use habitats that are scattered across continents and
confront hazards throughout the annual cycle that may be population-limiting. Identifying …

The Bay of Fundy, Canada is a critical staging area for Semipalmated Sandpipers (Calidris
pusilla) during post-breeding migration. Recent range-wide population declines and …

Knowledge of the role of individual associations has provided an insightful understanding of
the structures of animal societies, especially in highly social mammals such as primates. Yet …

Developing effective species conservation strategies relies on our ability to understand the
spatiotemporal distribution of birds across their annual cycle. Assessing the connectivity …
