Description
The Yellow-rumped Honeyguide is sparrow sized and has a stout finch-like bill. The plumage is largely dusky olive and the forehead and lores are orange while the upper plumage. There is a streaked appearance to the wing feathers. The rump is deep orange and extends into the back grading to sulphur yellow. The chin and throat are yellowish while the lower plumage is pale grey with dark streaks. The bill is yellow but dark towards the tip. Females have less extensive yellow on the face and the rump is yellow and lacks the orange. Allan Octavian Hume described the subspecies radcliffi (after Colonel E. Delmé-Radcliffe) based on specimens from Hazara but no specimens or information from the region have subsequently been obtained putting it in some doubt. The species was described by Blyth based on specimens from near Darjeeling. Ripley described specimens from the Naga Hills as subspecies fulvus (not always recognized), said to be smaller and darker, with the streaking on the abdomen reduced and the yellow on the forehead restricted to the anterior. This population may be identical to the nominate of the eastern Himalayas. They have twelve tail feathers and nine primaries. The wing is long and pointed.

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)
“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)
“As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.”
—Henry David Thoreau (1817–1862)
