Just out of curiosity. . . I know (or at least I was told by a falconer at a ren fair) that hawks and falcons are differentiated by the type of prey they generally go after. . . Hawks mostly take their prey on the ground, rodents and the like, and they have longer legs which makes it easier for them to move around in tall grass on the ground; Falcons mostly hunt other birds and take them on the wing, and generally have longer wingspans for their size. So what differentiates eagles from hawks and falcons? Is it just size, or something else? Could the bird you saw have been an eagle morrowj?
