The eared grebe Podiceps nigricollis shows seasonal variation in the relative size of the major flight muscles that lift and lower the wing: respectively, supracoracoideus (s) and pectoralis (p). S/p ratios are low ( 0.07 0.12) when grebes are in flying condition, higher ( 0.11 0.15) when staging an...
