Energetics of the moult fast in female macaroni penguins Eudyptes chrysolophus
The metabolic rate of moulting macaroni penguins Eudyptes chrysolophus was investigated using three techniques in order to test two hypotheses concerning the energetic cost of the moult fast in penguins. First, that energy expenditure during the moult is greater than that while penguins are onshore...
