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 …

Partial migration—wherein migratory and non‐migratory individuals exist within the same
population—represents a behavioural dimorphism; for it to persist over time, both strategies …

Seasonal bird migration may provide energy benefits associated with moving to areas with
less physiologically challenging climates or increased food availability, but migratory …

Long‐distance migrations are among the most physically demanding feats animals perform.
Understanding the potential costs and benefits of such behaviour is a fundamental question …

Elucidating the full eco‐evolutionary consequences of climate change requires quantifying
the impact of extreme climatic events (ECEs) on selective landscapes of key phenotypic …

Seasonal migration is intrinsically connected to the balance of survival and reproduction, but
whether migratory behavior influences species' position on the slow-fast continuum of life …

One enduring priority for ecologists has been to understand the cause (s) of variation in
reproductive effort among species and localities. Avian clutch size generally increases with …

One approach to stabilise small and declining populations is to breed individuals in captivity
and release them into the wild to reinforce existing populations while working to reduce …

Understanding how breeding populations are spatially and temporarily associated with one
another over the annual cycle has important implications for population dynamics. Migratory …

Seasonal variability in environmental conditions is a strong determinant of animal
migrations, but warming temperatures associated with climate change are anticipated to …
