Weight : c? 15^ & 12 lbs. ; ? 13^ lbs. 



I had at first thought that the east African bird was 

 different from the south African, but 1 have come to the con- 

 clusion that the two south Africau specimens in the British 

 Museum (one marked S. Africa, the type of 0. stanleyi Gray, 

 [Zool. Misc. 1831, p. 12 ] ; and the other from Potchefstroom) 

 are both immature, as they agree perfectly with a specimen 

 from British East Africa that is undoubtedly immature. 



These differ from the adult in their smaller size, in being 

 much more sandy above, in having the lores, cheeks, and 

 ear-coverts distinctly huffy and more finely marked, and in 

 the grey of the neck and breast being vermiculated with 

 black and buffy. 



The striking difference between the size of the adults and 

 young is shown as follows: — Young South African bird, no 

 sex, has the wing 446 mm.; a Potchefstroom female has the 

 wing 487 mm, ; one from B. E. A , no sex, has the wing 

 480 mm.; and the adults, on the other hand, have the wing : 

 a male in the British Museum from Lake Naivasha609 mm., 

 and others as stated above. 



[Irides brown; bill, upper mandible dark brown, lower 

 greenish ; legs and toes dirty white, dirty yellowish white, or 

 dirty cream. Tolerably common, usually in paiis.]
