Hawk, Cooper's
-Accipiter cooperii (Bonaparte)

Accipter outline. Similar to the Sharp-shinned Hawk in all plumages but decidedly larger with relatively stouter legs and a rounded tail; in adults the blackish cap is more or less well-defined against the colour of the back and lower neck. The Goshawk, which is decidedly larger and in adults differently coloured below, is separable by the tarsus, more than half of which is feathered, less than half in Cooper's. The Broad-winged Hawk is of about the same size as Cooper's, and immatures are similarly coloured, but the Broad-wing lacks the Cooper's heavy barring on the underside of the flight feathers and has only three outermost primaries emarginate (five in Cooper's).
