Comparison of Methods for Evaluating Energy Expenditure of Incubating Wandering Albatrosses
International audience Measurements of incubation energetics can vary depending on the method used to measure metabolism of an incubating bird. Therefore, we evaluated the energy expenditure of six male and four female wandering albatrosses (Diomedea exulans Linnaeus) using doubly labeled water (DLW...
