402 ]\rr. A. L. Butler on Birds observed 



that was calling somewhere near, and on returning noticed 

 a dark lump on the top of a small leafless tree which, I 

 remembered, had no such lump on it in the daytime. A 

 shot at this object resulted in its remaining stationary, but 

 its shape seemed to have changed, and on my shaking the 

 tree the little Owl fell to the ground. 



57. Bubo ascalaphus Sav. 



The Desert Eagle-Owl was often heard at night among 

 the hills, but T did not come across it in the daytime. 



58. Falco, sp. inc. 



A pair of Falcons were noticed several times at the Khor 

 Arbat, but were not identified. 



59. Helotarsus ecaudatus (Daud.). 



I saw a single Bateleur Eagle in the Khor Arbat, and a 

 pair at Jebel Bawati. 



60. Aqlila imperialis Bechst. 



A pair of Imperial Eagles frequented the Khor Arbat, 

 and used to glide along the higher slopes of the hills 

 in sight of my tent every day, apparently hunting for 

 Hyraxes. I saw another pair on Jebel Bawati. I was 

 anxious to get a specimen, and, as it was useless to climb 

 about such steep hills after birds with such powers of wing, 

 I set a trap for them, baited with a dead kid, on the summit 

 of a small hill within view of my camp. I soon, however, 

 got tired of climbing up and down five hundred feet of 

 rock to release Egyptian Vultures, and had to give up the 

 attempt. A rat-trap with the teeth blunted held the Vultures 

 without injuring them at all. 



61. BUTEO DESERTORUM (Daud.). 



I saw these Buzzards daily in the Khor Arbat. 



62. Gyps rueppelli Brehm. 



Vultures, which I think belonged to this species, were 

 frequently seen high in the air. 



63. Neophron percnopterus (Linn.). 

 Egyptian Vultures were abundant everywhere.
