The median for fat and muscle scores in brackets. Fat mass and lean mass (g) were obtained by QMR scanning, body mass (g) was obtained by digital scale and wing chord (mm) was measured with a ruler. Sex was determined by plumage in dimorphic species and by molecular methods in monomorphic species. Some individuals remained unsexed. Sample sizes in parentheses.
