elliptical patch aloug the base of upper mandible anterior to the eye, lower part of neck, under parts generally, and sides, middle 
and greater wing coverts, the innermost secondaries (and tertials, except the innermost three or four) white. The white on the 
wing is in a continuous patch, although there is a concealed black bar on the bases of the greater coverts. The inner scapulars 
are white, margined externally with black, posteriorly, however, they are black, streaked centrally with white. The inner 
scapulars and tertials, and the whole back, rump, and lesser wing coverts are black; the primaries and tail black, with a hoary 
gloss. The under side of quills and lower greater coverts are plumbeous gray ; the rest of the under wing and the axillars are 
sooty brown. The long white feathers of the flanks are edged superiorly with black. 
Female with the head and neck above snuff brown, without white patch. White of wing less extended ; ,the middle coverts 
only touched with white. There is a tendency to a black bar across the tips of the greater coverts. The white of the wing 
sometimes well denned.
