However, protein is also catabolized during flight (for reviews, see Jenni and Jenni-Eiermann, 1998; Bauchinger and Biebach, 1998), and some of it is stored before flight bouts (McLandress and Raveling, 1981; Marsh, 1984; Piersma and Jukema, 1990; Gauthier et al., 1992; Lindström and Piersma, 1993).
