The Juvenal plumage fades with wear, and loses some of the bright 

 Clay Color above and becomes almost whitish on the underparts. 

 In Kenya V. G. L, van Someren (1922, p. 147) found the postjuvenal 

 molt to begin in June. One such specimen before me shows the 

 very onset of the molt — a few yellow feathers coming in on the whitish 

 abdomen and breast, while the upper parts are as yet unaffected. 



Adult female in fresh plumage: Feathers of forehead, crown, 

 occiput, nape, back, rump, upper tail-coverts and upper wing-coverts 

 with broad Fuscous shaft stripes, broadly edged and tipped (less 

 broadly) with Olive-Brown, dark medial streaks averaging heaviest 

 on head and upper back, slightly less pronounced on rump and upper 

 tail-coverts. Remiges and rectrices Olive-Brown to Clove Brown, 

 narrowly edged with pale Olive-Brown. Lores and superciliary line, 

 cheeks, auriculars, and sides of neck light Dresden Brown to Buck- 

 thorn Brown to Tawny-Olive. Chin Chamois to Cream-Buff.

 dusky Isabella Color, with narrow darker shaft streaks. Abdomen 

 Cartridge Buff darkening to pale Chamois near the vent and on 

 under tail-coverts. Lender wing-coverts pale Tawny-Olive. Iris 

 bro^vn. Bill and feet brown. Size as in male.

 but paler edges of the feathers of upper parts of head and bodj'^ 

 narrower (by abrasion) and paler (by fading), Buffy Brown, causing 

 the dark shaft streaks to be more pronounced. Lores, superciliaries, 

 chin, throat, cheeks, auriculars vary from pale Mustard Yellow to 

 Light Buff. Feathers of breast, sides, and flanks pale Buffy Brown, 

 with dusky Buffy Brown medial streaks. Abdomen Light Buff.
