All animals face the possibility of limitations in food resources that could ultimately lead to
starvation-induced mortality. The primary goal of this review is to characterize the various …

Migratory birds are physiologically specialized to accumulate massive fat stores (up to 50–
60% of body mass), and to transport and oxidize fatty acids at very high rates to sustain flight …

Migration, broadly defined as directional movement to take advantage of spatially distributed
resources, is a dramatic behaviour and an important component of many life histories that …

Once-abundant aerial insectivores, such as the Tree Swallow (Tachycineta bicolor), have
declined steadily in the past several decades, making it imperative to understand all aspects …

The nutritional diversity of resources can affect the adaptive evolution of consumer
metabolism and consumer diversification. The omega‐3 long‐chain polyunsaturated fatty …

The influence of seasonal changes in temperature and climate on metabolic rates in birds
has been a topic of interest to ornithologists and ecophysiologists for decades (eg, Hart …

Billions of animals migrate each year. To successfully reach their destination, migrants must
have evolved an appropriate genetic program and suitable developmental, morphological …

The metaphor of marathon running is inadequate to fully capture the magnitude of long-
distance migratory flight of birds. In some respects a journey to the moon seems more …

The expression of most life history traits, such as immunity, growth and the development of
sexual signals, is negatively affected by high levels of oxidative stress. Dietary antioxidants …

Long-distance migrants have evolved specific adaptations that make their athletic records
possible. Unique mechanisms explaining their amazing capacity for endurance exercise …
