In the pre-steel days, a major source of lead in eagles was from wounded waterfowl, esp. along the Mississippi River but also in other regions (e.g., eastern KS). Lead from deer carcasses is pretty minor in the way of affecting eagle population dynamics (probably what you mean to imply by "SPECIES") though undoubtedly a few must get lead that way occasionally.

In eastern KS where much/most dove hunting is done over farm ponds and shallow flooded basins, steel shot might make sense. But in Iowa, I have no idea where the predominant hunting habitats will be. I hear about folks planting sunflowers and shooting them, basically over bait fields, but hell, why bother with doves in IA in the first place?
