Description
This species averages 49 to 55 cm long, with a wingspan of 96 to 110 cm and a tail length of 20 to 25 cm. Males average 85% of the size of females. Like the other chanting goshawks, it resembles an accipiter but the tail is shorter and graduated (the feathers increase in length from the edges to the center), and the wings are broader.
Adults have grey head, neck, breast, and upperparts, except for the white or lightly barred upppertail coverts. The belly has narrow grey and white bars and the undertail coverts are white. The belly and wing linings are white, the secondaries are light grey, and the primaries are dark, giving an impression from below of a white bird with grey head and dark wingtips. The tail is blackish above and white below with grey bars. The cere is yellow, and the legs are orange-red. Juveniles are dull brown above with a pale stripe over the eye. They have white underparts with brown streaks on the throat and breast, brown bars on the belly coverts, and faint or no barring on the undertail coverts. The tail is brown with widely spaced darker brown bars. The rump is white, partially barred or unmarked. They are indistinguishable from some juvenile Dark Chanting Goshawks except for the less barred undertail coverts and rump. Also, the legs are slightly longer at all ages than the Dark Chanting Goshawk's.

Famous quotes containing the word description:
“Once a child has demonstrated his capacity for independent functioning in any area, his lapses into dependent behavior, even though temporary, make the mother feel that she is being taken advantage of....What only yesterday was a description of the child’s stage in life has become an indictment, a judgment.”
—Elaine Heffner (20th century)
“Do not require a description of the countries towards which you sail. The description does not describe them to you, and to- morrow you arrive there, and know them by inhabiting them.”
—Ralph Waldo Emerson (1803–1882)
“It is possible—indeed possible even according to the old conception of logic—to give in advance a description of all ‘true’ logical propositions. Hence there can never be surprises in logic.”
—Ludwig Wittgenstein (1889–1951)
