Birds also have high surface to volume ratios and comparatively small energy reserves causing additional energetic challenges during periods of food limitation or complete starvation. During starvation, energy can be saved if the need for acti

In this review we demonstrate that it is the extraordinary ability of birds to extensively store and use lipids as the main energy source which allows them to fast

A new hypothesis suggests that the rate of tissue-specific degradation during fasting is related to the tissue-specific rate of protein turnover. This hypothesis predicts allometric sca

However, besides its clear ecological advantages, the evolution of powered flight brought about high energetic costs for bats. To compensate for these costs, bats have evolved a variety of energy-savi
