Data from: Does water temperature affect the timing and duration of remigial moult in sea ducks? An experimental approach
Aquatic birds have high cost of thermoregulation, especially during the moulting period, yet the effect of water temperature on the moulting strategy of aquatic birds has rarely been studied. Our general hypothesis is that energy savings associated with lower thermoregulation costs would be allocate...
