Moult in adult Royal Penguins, Eudyptes schlegel
Mass change during moult was measured in Royal Penguins at Macquarie Island during 1995, in order to estimate the energetic costs and prey-consumption rates required to fuel the moult. Masses of 30 birds were taken during each of the following stages: upon their return from the pre-moult foraging tr...
