Athene xoctua glaux. 



Carine meridionalis Shelley, p. 177. 



I have at present no specimens of the Little Osvl from the 

 Wadi Natron, but during my stay in November 1911 I 

 saw several examples towards dusk, amongst rocks in the 

 desert. None were seen in March 1910. 



[Bubo ascalaphus. 

 Bubo ascalaphus Shelley, p. 180. 



I have no specimens of this Owl from the Wadi Natron, 

 but Mr. Balboni tells me that he has met with it there.] 



Circus cyaxus (Linn.). 



Circiis cyanus Shelley, p. 182. 



On my arrival in the Wadi on November 22nd, 1911, 

 Mr. Balboni gave me a young female Hen Harrier which had 

 been shot the previous day. I subsequently saw one or two 

 individuals in the brown plumage of immaturity, but was 

 unable to obtain further specimens. 



Circus ^ruginosus (Linn.). 



Circus ceruyinosus Shelley, p. 181. 



The ]\Iarsh Harrier was frequently seen during my visit 

 in March, and Mr. Balboni has since forwarded several 

 immature examples. Possibly it nests in the great tracts of 

 bulrushes which fringe most of the Lakes. In November 

 1911 I saw a few Marsh Harriers near the Salt Lakes. 



Circus macrourus. 



Circus pallidus Sykes, Shelley, p. 183; Loat, Ibis, 1905, 

 p. 458. 



When travelling by train to the Wadi Natron in March 

 1910, I saw an adult male of this species, just before we 

 sighted the Wadi. It was circling over the desert. 



During my visit I saw one or more adult examples daily, 

 and specimens were obtained. 



BuTEO FEROX FEROX (Gm.). 



Buteo ferox Shelley, p. 201. 



On March 21st, 1910, a single Long-legged Buzzard was 

 seen. This species is easily distinguished from B. huteo
