Energy requirements of female macaroni penguins breeding at South Georgia
1. Breeding female Macaroni Penguins (Eudyptes chrysolophus ) were implanted with heart rate, temperature and depth data loggers in order to estimate their rate of energy expenditure from heart rate. 2. The estimated average daily metabolic rates (ADMR) of birds during the brood and creche phases of...
