PARASITIC WEAVERBIRDS 135 



and the nuchal collar than a long series from Angola, Bechuanaland, 

 and South Africa — almost Ochraceous Orange as opposed to Ocbra- 

 ceoiis Buff in the latter group. One Bulawayo example, however, 

 is like the Bechuanaland Angola birds. 



Adult male ix kon breeding plumage: Very different from the 

 above. Forehead, lores, crown, occiput, nape, back, upper tail- 

 coverts, and upper wing-coverts, very pale Wood Brown to very pale 

 Tawny-Olive, with each feather having a broad median shaft streak of 

 Fuscous, Streaks narrower on the crown and occiput, broadest on 

 the upper back and sometimes almost disappearing in upper tail- 

 coverts, or at least paling there to ashy Benzo Brown. Median 

 streaks on head tending to be less pronounced on feathers of the mid- 

 dorsal area, producing an ill-defined appearance of darker superciliary 

 bands on either side. Inner secondaries dark Fuscous, broadly edged 

 and tipped with very pale Tawny-Olive. Other secondaries Fuscous 

 with no paler margins. Primaries paler, Benzo Brown, basally mar- 

 gined on their inner webs with, pale ashy to whitish. Four median 

 rectrices Fuscous-Black, narrowly edged and tipped with buffy white 

 and slightly longer than more lateral ones, which are Natal Brown, 

 broadly tipped and lateroterminally edged with white. Chin, cheeks, 

 throat, breast, sides, and flanks ashy Pinkish Cinnamon, palest on 

 chin, tinged with Ochraceous-Tawny on cheeks, lower breast and 

 sides. Abdomen, under tail-coverts, and thighs white. Bill pale 

 pinkish brown. Feet light brown. 



Adult female: Similar to male in nonbreeding plumage, but 

 usually with chin, throat, cheeks, breast, and sides whiter, less tinged 

 with very pale Ochraceous Tawny, and (in limited material examined) 

 usually with pale margins of feathers of upper parts somewhat nar- 

 rower. Rectrices Natal Brown. Lateral ones tipped and latero- 

 terminally edged with whitish (in a single example one new inner 

 rectrix coming in is Fuscous-Black narrowly edged and tipped with 

 white; either the sex of this specimen is wrongly given, or the tail of 

 the female may become like that of the nonbreeding male). 



Juvenal (sexes probably alike, but only i of each sex ex- 

 amined): Forehead, crown, occiput Cinnamon-Drab to Tawny-Olive, 

 unstreaked. Hind neck paler, forming an indistinct nuchal collar of 

 ashy pale Tawny Olive, Upper back and upper tail-coverts dusky 

 Ta'N^iiy Olive, feathers with wide shaft streaks of dark Benzo Brown 

 to pale Fuscous. Rump and upper tail-coverts similar but without 

 dark median streaks. Remiges and rectrices dark Olive Brown to 

 Fuscous, externally edged wath pale Tawny-Olive, Primaries in- 

 ternally edged basally with buffy white. Lores slightly duskier than 

 crown. Chin, cheeks, throat, breast, sides, flanks, and thighs pale 

 Tawny-Olive, more intense on breast and upper sides. Anterior
