Dark morph Ferruginous Hawk
観察結果の詳細
One was a dark morph Ferruginous. The two flew together calling occasionally. The dark morph has a dark grayish head, long yellow gape, rufous belly and dark upper chest, legs feathered to the feet, white tail. According to Brian Wheeler's "Raptors of Western North America," this is a dark rufous morph Ferruginous Hawk. In flight, the underwings were dark and the primaries and secondaries were white. The adult non-dark morph had a gray head, white below with a white tail with a slightly rufous smudge at the terminal end of the tail. The breast and belly were white as was much of the underwing. However on the underwing, there were the classic line of dark under wing coverts making a "comma" followed by a straight line. The leg feathers were rufous. Above, we could see a large patch of rufous on the wing surfaces.
