Abstract Many bird species show a loss of female muscle mass at the time of egg formation. In this study we investigated whether there was a causal link between the loss in muscle condition and the formation of egg proteins by feeding 35S-methionine to female zebra finches to label muscle proteins. When these birds subsequently bred the isotope was transferred to the egg proteins: isotope loss from female muscle tissue was significantly greater in birds which had bred than in control groups which had not.
