text: Like several other penguin species, the macaroni penguin sometimes deliberately swallows small (10– to 30-mm-diameter) stones; this behaviour has been speculated to aid in providing ballast for deep-sea diving, or to help grind food, especially the exoskeletons of crustaceans which are a significant part of its diet.
