1. Resting metabolic rate was determined in Adelie penguins (Pygoscelis adeliae) that had been fed warm and cold ingesta. 2. Post-ingestion metabolic rate was found to be related to food temperature rather than to specific dynamic action. 3. Calorimetric calculations indicate that up to 13% of Adelie penguin daily energy expenditure may be used heating ingested food to body temperature. 4. Heating food costs are predicted to be higher in endotherms living in cold regions and in species with low assimilation efficiencies, but may be minimized by appropriate foraging behaviour. |
