 of ear-coverts; on sides of breast and on fore neck a tinge of vinous-buff

 black, and fringed at the tips with a narrow blackish line, giving the rump 

 the appearance of being lined transversely with black; feathers of head 

 blackish, varied with brown or whitish edges, and forming a more or less 

 distinct cap, which is separated from mantle by the light color of hind
