Duration is means ± SE. All other values are least squared means ± SE, with body mass and flight duration included as covariates All Flights, and body mass included as a covariate for the 360-min Flights. MUFA, monounsaturated fatty acids; PUFA, polyunsaturated fatty acids; RPC, relative protein contribution.
