 lighter and more green on the head, wing, and tail-coverts. Lores and a line behind the 

 eye brownish black; across the forehead a narrow and above the eyes a conspicuous 

 orange-yellow superciliary stripe. Quills deep brown, outer webs edged with greenish 

 yellow. Chin, throat, and upper breast bright orange-yellow ; abdomen yellow and 

 fading into pale greenish grey on the vent and under tail-coverts. 



Adult female or immature male (in the Senckenbergische Museum at Frankfort). Above dull 

 brownish olive, tinged with greenish on the top of the head, rump, and upper tail-coverts, 

 and on the edges of the quills and tail-feathers. Lores dusky ; a somewhat ill-defined 

 but distinct superciliary stripe ; sides of head and throat yellowish. Rest of underparts 

 light greyish brown, brownish olive along the sides of the body and flanks. 



An immature male in the Leiden Museum is similar to the specimen in the Frankfort Museum, 

 but much more strongly tinged with yellow on the throat and sides of the head, the 

 edges of the quills more yellowish.
