Females are all black. There is a bluish white neck patch and the tail is white in both sexes. Both males and females have a bill with a few folds on the upper side towards the base of the upper mandible. The skin around the eye is bluish. The iris of the male is orange red while the female has an olive brown with a pale yellow ring. The bill is waxy and the furrows of the casque are brownish. The bill is pinkish towards the base. The legs are black and the sole is yellow.
Adults have a ka- ka- ka call in flight and a ko ... kokoko..ko..kok.. kok.. call at the nest. The young in the nest produce feeble chew calls. Courtship involves ritual feeding. They sometimes mob White-bellied Sea Eagle that fly too close. The favoured nesting trees are Sideroxylon and Sterculia species.
The species was described by Allan Octavian Hume in 1873.

Famous quotes containing the word description:
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
“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)
“To give an accurate description of what has never occurred is not merely the proper occupation of the historian, but the inalienable privilege of any man of parts and culture.”
—Oscar Wilde (1854–1900)
