The soft parts of an adult are : — Irides brown ; bill slaty, 

 darker at tip ; cere and round eye yellow ; legs and toes 

 the same. In the young the colours are much duller.] 



509. Cerchneis rupicoloides. 



CC. Klipfoutein, June (1); Z. Umfolosi Station^ July 

 (3) ; Tv. Turflop, Mch. (2). 



In this case also the Namaqualand example is slightly, 

 but perceptibly, paler than those from Zululand and the 

 Transvaal. 



The transverse barring on the flanks is absent from two 

 females obtained at Umfolosi dated July 14 and 24-. 

 In these cases the light bauds of the tail are pale tawny and 

 not slaty blue, and the birds appear to be immature. An 

 adult female from Turflop has the thigh-bands and only 

 differs from the male in size. Reichenow has suggested that 

 the absence of the thigh-bands is a female characteristic. 

 It appears to me that their absence is merely a sign of 

 immaturity. 



[Unlike C. rupicola, this species is often found a long way 

 from mountains or kopjes. It is generally seen perched on 

 some low or stunted bush, and when disturbed merely goes 

 ofl" with a low flight to some other position a hundred yards 

 or so away. It appears to be more or less solitary, and feeds 

 principally on mice and. insects, while I can find no record 

 of having seen it chasing small birds. 



The soft parts of an adult are : — Irides silver-grey ; bill 

 light slaty, darker at tip; base of lower mandible, cere, 

 and round eye lemon-yellow ; legs and toes lemon-yellow.] 



510. Cerchneis naumanni. 



Tv. Wakkerstroom, Mch. 2, 14, and 30 (4). 



The two males are interesting, as they are both getting 

 their blue heads by a gradual feather-change, and by the 

 wearing away of the edges of the old feathers. 



[I have observed this Kestrel only twice — when several 

 flocks passed through the Wakkerstroom district during 

 March 1901, and when a single flock passed close to 

 Pietersburg in March 1906, going south, but Avcre too high
