Abstract
Jackass penguins were fed either fish, squid, or a mixture and then stomach pumped at increasing time intervals after ingestion. The squid took longer to be evacuated from the stomach than the fish in all cases. Care should be exercised when interpreting bird diets using the volume or mass of stomach contents.This publication has 1 reference indexed in Scilit:
