A glance at different members of the Eagle tribe will at once convince us that they do not all belong to the same country or climate. It is true that they are dispersed over the surface of the whole earth, but each species has its appointed district; all, however, avoid the abodes of man, and make their nests in some unfrequented spot. Mountains, forests, sea-coasts, or the banks of lakes or rivers have each their appointed forms, while some species roam at large over the open plains of the countries in which they live. Such members of the family as inhabit the more northern portions of the globe migrate as winter approaches, and pass their lives in sweeping from land to land, except at such times as they are busied with the cares of incubation. In their habits all are unsocial, keeping company rarely even with individuals of their own race, except during their winter journeyings, and suffering no intruder to approach the spot selected as a breeding-place; so strong is this dislike to society that even when several Eagles are attracted by the same prey the companionship is merely in appearance, each bird coming and going without any reference to the movements of the rest. Notwithstanding this unwillingness to join company with others, even of their own species, they are much attached to their mates, each pair living in close companionship throughout their whole lives, and frequently permitting smaller birds to make their nests in close proximity, either regarding them as entirely beneath their notice, or, perhaps, feeling that such despicable morsels are not worth the long and troublesome chase which their pursuit would necessitate. To some members of the Eagle family the name of Hawk Eagles has been assigned, on account of their very decided resemblance to the Hawk, not merely in appearance, but in disposition.
