dant on all the maritime plains. It appears to retire to the northern 
mountains to breed. 
6. AQUILA HELIACA, Sav. 
We frequently saw the Imperial Eagle. On one occasion in the 
early morning, in the valley of Dothan, a bird slowly passed close to 
us, the most magnificent specimen I ever saw, with its white scapu- 
lars splendidly distinct. We did not succeed in finding its nest ; but 
it remains throughout the year. I had a specimen given me in 
Beyrout in the immature plumage, in which it has been described 
as A. bifasciata. 
7. Aquinas Na&vIA, Br. 
Not uncommon, especially in winter. A specimen, which I showed 
to Mr. Gurney, that gentleman pronounced to be the large variety 
called A. clanga by Pallas. 
8. AQuUILA N&VIOIDES, Cuv. 
Frequent throughout the year. 
9. AQuiILA BONELLII (Temm.). 
Common at all seasons, but restricted more than the preceding to 
the hills and wooded districts. 
10. AqurLa PENNATA (Gm.). 
One of the first birds of prey we noted on the Lebanon in No- 
vember. Seen occasionally throughout the year, but only in the 
north. Mr. Upcher obtained a specimen in March on the Lebanon. 
11. Panpion waciaitrus, L. 
Noticed frequently at all times of the year on Mount Carmel and 
near the Kishon. 
12. CrrcakTos GALLICUs, Gm. 
Beyond all doubt the most abundant of all the Eagles in Palestine, 
at least in spring. I am not sure that I ever saw it but once in 
winter ; and that was in the sheltered groves of Sidon. From the 
beginning of March we met with it everywhere. It is rather a late 
breeder for an Eagle, as we found its eggs quite fresh at the end of 
April. We never found more than a single egg in each nest. The 
male bird appears to incubate by turns with the female. 
13. BuTeo vuxearis, Bechst. 
Common in winter on the plains. Not observed in spring. 
14. BurEo rRuFiINnus, Riipp. 
Extremely numerous in every part of the country and at all times’ 
of the year. In winter it congregates in small flocks over the plains 
of Judea, but during the breeding-season is segregated in pairs in
