two species is that in loth sexes, and at all seasons, the ear coverts and aural 

 region are in personala black, blackish, or dark grey; in dukhenensis = alba 

 pure white or greyish or sordid white." 



Sharpe (Cat. B. Br. Mus. x. p. 481) says that old birds in winter plumage 

 are remarkably like the summer plumage, and have the same black ear coverts, 

 the chin, however, is white, as well as a good deal of the throat and the forepart 

 of the cheeks, so that a narrow black stripe is left between the white lores and 

 white cheeks, running from the base of the bill to the ear coverts. It seems 

 certain, he adds, that old birds have the white chin spot for a short time only, 

 for December specimens have nearly got the full black chin. 



The female in breeding plumage (Gilgit, Scully,) exactly resembles the 

 male. Length 6-5 inches ; culmen O'5 ; wing 3-5 ; tail 3-3 ; tarsus 0*9.
