The young birds of this and the foregoing species have 

 evidently been hatched during a breeding season in connec-

These specimens are pretty similar inter se, but do, of 

 course, display some variation as usually is the case with 

 birds of this genus. All four are rufous-tailed with the 

 lower tail-coverts white, washed with rufous. 



The specimen from Juja has the lower wing-coverts black, 

 primary and small upper coverts mostly black; only 4 (resp. 

 5) quills are edged with white, and the 4- (resp. 3) innermost 

 secondaries are chiefly rufous. One of the specimens from 

 Donya Sabuk has much more white among the primary and 

 small upper coverts, and also the lower coverts partly mixed 

 with white, otherwise the wings are similar. It might now 

 be expected that the specimen with more white on the wing- 

 coverts was an older bird. This is, however, not the case 

 as may be concluded from the fact that the bird from Juja 

 with less white has a much stronger metallic gloss on head, 

 neck and upper breast. The other bird from Donya Sabuk 

 has the upper and lower wing-coverts chiefly white, but is 

 otherwise similar and as glossy as the Juja bird. The bird 

 from Athi river has 8 (9) quills edged with white and none
