White-tailed eagle more vulnerable than many. Besides vulnerability, habitat and prey behaviour, fish body size may be a driver in the piscivorian dietary preferences. Studies have indicated that fish less than are taken infrequently, since they have a lower yield, fish of up to are taken secondarily and fish between are preferred since they have the highest nutritional benefit. Fish taken can exceed but since they can start to considerably exceed the weight of the eagle itself, they may be prove too difficult to overpower. One large Atlantic halibut ("Hippoglossus hippoglossus") was found with the disembodied feet of a white-tailed eagle still
