Resource tracking, where animals increase energy gain by moving to track phenological
variation in resources across space, is emerging as a fundamental attribute of animal …

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 …

In terrestrial systems, the green wave hypothesis posits that migrating animals can enhance
foraging opportunities by tracking phenological variation in high-quality forage across space …

In 2007, the first miniature light-level geolocators were deployed on small landbirds,
revolutionizing the study of migration. In this paper, we review studies that have used …

Animals and plants are shifting the timing of key life events in response to climate change,
yet despite recent documentation of escalating phenological change, scientists lack a full …

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 …

Although it is known that birds can return to their breeding grounds with exceptional
precision, it has remained a mystery how they know when and where to stop migrating …

Species environmental niches are central to ecology, evolution, and global change
research, but their characterization and interpretation depend on the spatial scale …

The evolution of migration routes in birds remains poorly understood as changes in
migration strategies are rarely observed on contemporary timescales. 1–3 The Richard's …

Newly emerging plants provide the best forage for herbivores. To exploit this fleeting
resource, migrating herbivores align their movements to surf the wave of spring green-up …
