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 …

Current ideas about the evolution of bird migration equate its origin with the first appearance
of fully migratory populations, and attribute its evolution to a selective advantage generated …

Migratory birds regularly perform impressive long-distance flights, which are timed relative to
the anticipated environmental resources at destination areas that can be several thousand …

Seasonal journeys between breeding and non-breeding habitat are undertaken by a diverse
array of animals. Parallel developments in tracking and genomic methods are enabling finer …

The evolution of long‐distance migratory behavior from sedentary populations is a central
problem in studies of animal migration. Three crucial issues that remain unresolved are:(1) …

The twenty-first century has witnessed an explosion in research on animal migration, in
large part due to a technological revolution in tracking and remote-sensing technologies …

There are wide reports of advances in the timing of spring migration of birds over time and in
relation to rising temperatures, though phenological responses vary substantially within and …

An increasing number of studies demonstrate that plant and animal phenologies such as the
timing of bird migration have been advancing over the globe, likely as a result of climate …

There is mounting evidence that global climate change has extended growing seasons,
changed distribution patterns, and altered the phenology of flowering, breeding, and …

The temporal and spatial organization of the annual cycle according to local conditions is of
crucial importance for individuals' fitness. Moreover, which sites and when particular sites …
