Timing is a crucial aspect for survival and reproduction in seasonal environments leading to
carefully scheduled annual programs of migration in many species. But what are the exact …

The “paradox of the great speciators” has puzzled evolutionary biologists for over half a
century. A great speciator requires excellent dispersal propensity to explain its occurrence …

A fundamental issue in migration biology is how birds decide when to start their journey,
given that arriving too early or too late in a variable environment reduces individual fitness …

Artificial light at night (ALAN) is increasing at a high rate across the globe and can cause
shifts in animal phenology due to the alteration of perceived photoperiod. Birds in particular …

Migration is an important event in the annual cycle of many animals that facilitates the use of
resources that vary across space and time. It can occur with regular and predictable timing …

Artificial light at night (ALAN) can cause circadian disruption and result in adverse
behavioral and ecological effects in free‐living birds, but studies on captive pet birds as …

Facultative migrations are observed across vertebrate taxa, include irruptive and nomadic
movements, and occur in response to ephemeral and unpredictably variable resources …

Physiological preparations for migration generally reflect migratory strategy. Migrant birds
fuel long-distance flight primarily with lipids, but carrying excess fuel is costly; thus, the …

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

The final stage of migration, when animals terminate migratory movements and transition to
a more sedentary state, remains the least understood phase of migration. Whereas migrants …
