In most long‐distance migratory birds, juveniles migrate without their parents and so are
likely to lack detailed knowledge of where to go. This suggests the potential for stochasticity …

Phenotypic differences among individuals can arise during any stage of life. Although
several distinct processes underlying individual differences have been defined and studied …

The first comprehensive review of all aspects of the biology of moult, drawing information
from across the literature and in all birds, from penguins to passerines. Feathers are …

Globally, bird migration is occurring earlier in the year, consistent with climate-related
changes in breeding resources. Although often attributed to phenotypic plasticity, there is no …

Flexibility in scheduling varies throughout an organism's annual cycle, reflecting relative
temporal constraints and fitness consequences among life-history stages. Time-selection …

Costs of migration, in terms of time, energy, and mortality risk, have a strong theoretical and
empirical foundation in the study of birds. We expect these costs to be most severe for …

Recent years have seen a growing consensus that events during one part of an animal's
annual cycle can detrimentally affect its future fitness. Notably, migratory species have been …

Events during one stage of the annual cycle can reversibly affect an individual's condition
and performance not only within that stage, but also in subsequent stages (ie reversible …

Abstract The Pacific Basin, by virtue of its vastness and its complex aeroscape, provides
unique opportunities to address questions about the behavioral and physiological …

Matching the timing of annual cycle events with the required resources can have crucial
consequences for individual fitness. But as the annual cycle is composed of sequential …
