and very sparingly on the road between that place and Batna. 

 Its habits and flight much resemble those of the preceding, 

 with which it associates. 



Aquila rapax. 



But one example of the Tawny Eagle was seen by us. A 

 fine specimen of this bird flew past me almost within gunshot 

 when Ave were in the evergreen-oak forests on the hills near 

 Lambessa. 



Aquila pennata. 



Mr. Elwes saw a bird which he took to be a Booted Eagle 

 in the valley below Constantine. 



' MiLVUS ATER. 



The Black Kite was certainly the commonest and most 

 widely distributed Raptorial bird we met with. From Con- 

 stantine it was to be seen daily, no matter what the nature of 

 the scenery might be. We met with it at an altitude of 6000 

 feet at Oued Taga, saw it in the cedar forests west of Batna, 

 and at El Kantara and Biskra it was our daily companion. 



Falco barbarus. 



We met with the Barbary Falcon at Constantine and El 

 Kantara. It breeds in the rocks at both these places. 



Falco eleonor^e. 



We only met with the Eleonora Falcon at Philippeville on 

 our return journey (16tli of May). On the verdant plain 

 S.E. of the town we witnessed a most extraordinary migra- 

 tion of this bird. It was assembled in flocks ; and I counted 

 as many as ninety on the wing together. They appeared to be 

 hawking for flies, and occasionally chased each other through 

 the air. Far from being shy, they repeatedly came within 

 gunshot, and perched on the tree-tops beneath which we 

 were standing. The whole party kept well together, and was 

 distributed over some twenty acres of ground. A few of the 

 birds kept alighting on the haycocks, and even on the newly- 

 ploughed land. The flight of this Falcon is a very peculiar 

 one, and much resembles many of the aerial movements of 

 the Bee-eater. In other respects it aj)proaches the hovering
