The Sanderling Calidris alba is a long-distance migratory wader that occurs worldwide in
coastal areas (particularly on sandy beaches) during the non-breeding season. The …

Evolutionary theories of seasonal migration generally assume that the costs of longer
migrations are balanced by benefits at the non‐breeding destinations. We tested, and …

Food insecurity is associated with high body weight amongst women, but not men, in high‐
income countries. Previous research using food recalls suggests that the total energy intake …

Escaping from a predator is a matter of life or death, and prey are expected to adaptively
alter their physiology under chronic predation risk in ways that may affect escape …

For small birds to survive during seasonal acclimatization in temperate zones, regulation of
body mass and thermogenesis is crucial. To determine the role of temperature and …

Abstract In the North Sea, during autumn-winter, intertidal flats often receive a massive influx
of migratory shorebirds (wildfowl, waders and seabirds), which utilise the high prey densities …

Background Food is an important environmental factor that affects animals' energy
metabolism and food shortage has significant effects on animals' behavior, physiology and …

Background Seasonal adjustments in body mass and energy budget are important for the
survival of small birds in temperate zones. Seasonal changes in body mass, body …

Maintaining homeothermy may be a major challenge when species are confronted with
ambient temperatures beyond their thermoneutral zone. Bird species occupying open …

Abstract Florida Scrub‐Jays (Aphelocoma coerulescens) in a suburban environment with
year‐round access to multiple sources of abundant, human‐source foods consistently breed …
