"Astur atricapillus. American Goshawk. Blue Hen Hawk (adult). Chicken Hawk (young). Adult: Above, dark bluish-slate color, each feather black-shafted; top of head blackish, conspicuously different from other upper parts, the feathers there with fleecy white bases; a long white superciliary or rather post-ocular stripe; auriculars blackish. Ground color of under parts, including lining of wings, white, closely barred or vermiculated in narrow zigzag lines with slaty-brown, except on throat and crissum, and everywhere sharply pencilled with blackish shaft-lines, one on each feather.

"Fig. 46. - Raptorial foot of a hawk, Accipiter cooperi. The raptorial is another modification of the insessorial foot. It is advantageous to a bird of pray to be able to spread the toes as widely as possible, that the talons may seize pray like a set of grappling irons; and accordingly the toes are widely divergent from each other, the outer one in the owls and a few hawks being quite versatile. In a raptorial character, the toes are cleft profoundly, or, if united at base, it is by movable webbing; the claws are immensely developed and the under-surfaces of the toes are scabrous or bulbous for greater security of the object grasped."
