1921 .] Birds of Lower Egypt. 
134. Aquila heliaca heliaca. Imperial Eagle. 
I several times observed Eagles soaring in the vicinity 
of Abu Zabaal, but was unable to identify them to my 
satisfaction. One which I saw sitting on the desert on 
14 February, 1914,1 was able to identify as the above species, 
from skins in the Giza Museum and notes made on the spot. 
135. Buteo buteo rufiventer. (= B. desertorum auct.) 
Steppe-Buzzard. 
I never shot one of these birds, although they were not 
uncommonly seen, but were always wide awake and difficult 
of approach. A single* bird remained in the vicinity of Abu 
Zabaal throughout September 1918. Also observed at odd 
times throughout the winter and early spring. 
It is quite possible that some of those seen were referable 
to Buteo ferox , but I was never quite satisfied that such was 
the case. Colonel Meinertzhagen has, moreover, shown 
that B. ferox cirtensis ranges into southern Palestine (Ibis, 
1920, p. 241). 
[Mr. M. J. Nicoll saw a pair in the Wadi Hof, apparently 
breeding, on 1 March, 1910. I saw a pair in the same place 
on 5 May, 1909. Another pair frequented the Giza gardens 
in May 1910, and probably bred there, as in June they were 
seen accompanied by two young birds.—R. S.] 
136. Circus aeruginosus. Marsh-Harrier. 
One or more birds haunted the Birket Accrashi through¬ 
out the winter. These were, almost without exception, 
immature birds. They were frequently mobbed by Hooded 
Crows, and waxed fat on any wounded birds we were unable 
to retrieve. A pair seen in the Wadi Natrftn on 24 May, 
1918, were possibly nesting. 
[I saw a pair at Inchas on 12. v. 09, and a single bird at 
Gheit-el-Nasara on 20. v. 09, so it is quite possible some 
pairs remain to breed in the Delta.—R. S.J 
137. Circus cyaneus cyaneus. Hen-Harrier. 
Less numerous than the following species. Two or three 
obtained during the winter and early spring.
