Última Energetic adjustments in freely breeding-fasting king penguins: does colony density matter? ArchiMer Viblanc, Vincent A.; Saraux, Claire; Malosse, Nelly; Groscolas, Rene. 1. For seabirds that forage at sea but breed while fasting on land, successful reproduction depends on the effective management of energy stores. Additionally, breeding often means aggregating in dense colonies where social stress may affect energy budgets. 2. Male king penguins (Aptenodytes patagonicus) fast for remarkably long periods (up to 1 center dot 5months) while courting and incubating ashore. Although their fasting capacities have been well investigated in captivity, we still know very little about the energetics of freely breeding birds. 3. We monitored heart rate (HR, a proxy to energy expenditure), body temperature and physical activity of male king penguins during their courtship and first incubation shift in a colony of some 24000 freely...
