Muskrats and waterfowl may not be the normal diet, but certainly adds to their diet. Studies suggest that large Esox would prefer to consume prey that would take less handling time to consume. On some pike/musky lakes, studies have found that up to 6% of the large fish did have waterfowl inside their stomachs and are also blamed for up to 10% of the total yound waterfowl mortality. They would still prefer to consume easier, soft-rayed fish, but other large, "unusual" food items still contribute to a significant part of their diets. At least during certain times of the year
