Breast Muscle Atrophy and Constraints on Foraging during the Flightless Period of Wing Moulting Great Crested Grebes

摘要

The paper aims to document body composition changes during wing molt in Great Crested Grebes and to show how food intake and feeding activity vary in the course of the molting period. The presented data give rise to new hypotheses and research questions, such as which levels of exercise are required to allow muscles to increase or decrease in size.
