On June 4 I found a huge nest ou an old Tereliinth-tree, close to another 

 big eiiii)ty nest, on which a Short-toed Eagle was sitting very close, -hatching 

 an addled egg. The Ijird proved to lie a male. 



A single bird was clearly observed at ISebseb, ol km. south of Cihardaia.

Two Kestrels, evidently migrating, were seeji on March 14. A siii;,'le female 

 was observed at Igosten on A])ril 1.5, and again — possii)ly the same bird— at 

 Iii-Salah, where also tlie remains of a dead specimen were found. 



A nest with four eggs (hard-set) was found iu the wall of the mined old 

 Berber town above the abattoirs of Ghardaia on May 3ti, and another with 

 half-grown young the following day. On the latter the female was caught with 

 the hand. 



Evidently nesting also in Guerrara (seen (i. vi. 1'J12}, Touggourt (12. vi.),

This lieautiful Falcon ranges from El-Kantara, where it nests, south to Ain 

 Guettara, where a pair was observed on April '.'T. It occurs, naturally, only where 

 rocks aiford opportunity for nesting. It does not, however, cling to inaccessible, 

 huge cliffs, but most of the nests we fonud were accessible without ropes, some 

 easily, others not without difficulty. Ou May 21 Hilgert discovered a nest with 

 half-grown young on a dift' not more than four metres in height, and barely three 

 above the ground. Through a mishap the old bird escaped ns, but a female, oft' 

 eggs, was shot on April !• in the southernmost Oued Mya, and an adult male in 

 the same region ou May 4. A young bird was killed in the Oued Nca, Jnne 4. 



A clutch of two, one hard-set, the other damaged, was taken, 9. iv. ; another 

 of two, almost fresh, ou April 11. The eggs are placed in small caves, always 

 protected from above, on the bare rock, and the nest is visible by the white 

 excrements. 



These birds are very shy, aud so are the Buzzards even there in those solitudes, 

 where they are rarely molested. 



The plumage and eggs will be described in my forthcoming part of the 

 Vog. d. pal. Fauna.
