Under parts white, tinged with fulvous on the flanks and abdomen; feathers of the throat and neck before tipped with black; those of other under parts with circular or oblong spots of black, large on the under tail-coverts; bill and feet horn-color. Sexes alike. Hab. Texas and Mexico. Spec. in Mus. Acad., Philada., and Nat. Mus., Washington. Obs. This bird somewhat resembles several of its genus, but is not difficult to distinguish. In many specimens, especially of the male bird, the black predominates on the throat and neck before, so as to present an almost uniform color. Several late writers have placed this species in the genus _Campylorhynchus_ (Spix).

This is one of the largest and most handsomely plumaged of the Rapacious birds of North America, though belonging to a division characterized by heavy and comparatively slow flight, and not manifesting any considerable degree of that courage and cunning which are generally so remarkable in this great group of the ornithological kingdom. In fact, on examination of the fine bird now before us, or of the Black Hawk of the Atlantic States, which is nearly related to it, one would scarcely infer that the object of such an admirable organization is nothing more important than the destruction of the smallest and most defenceless of quadrupeds or of reptiles. Yet such is apparently the case; many of the birds of this group, though powerful in structure, and furnished with the usual apparatus of strong and sharp bills and claws, and other accompaniments of predatory habits, rarely attack any animal more formidable than a mouse or ground-squirrel, or in some cases a frog or other of the weaker species of reptiles.
