the Straits of Gibraltar. 343 



adult specimens have occiu'red in winter near Seville [vide 

 Ibis, 1877, p. 418). 



Haliaetus albicilla. 



Mr. Stark, during the first week in May 1876, found a 

 nest of the White-tailed Eagle on a cliff on the coast. I 

 refrain from mentioning the exact locality for obvious reasons. 

 The nest contained one young bird nearly able to fly. 



Elaxus c^arLEUs. 



Mr. Stark saw one of these Hawks near Yejer on the 10th 

 of May, 1876. 



Cypselfs pallidus. 



The Pallid Swift is found as far north as Granada and Lan- 

 jaron. It nests at Gibraltar in holes of the sea-wall, also in 

 the roof of the patio of the convent, where Mr. Yerner took 

 several nests with eggs and young. The eggs and nest re- 

 semble those of C. apus ; but the young are, if any thing, very 

 slightly less marked with white. 



Piers xuMiDicrs. 



Comparing Moorish specimens with Andalucian specimens 

 of P. major, I fail to detect the difference, pointed out by 

 Messrs. Sharpe and Dresser, that the Afiican bird has a 

 longer and more slender bill. Andalucian specimens of P. 

 major sometimes run very closely to the African form in 

 having crimson markings on the breast, but are never, so far 

 as I have seen, so decidedly marked. 



Gecin'us taillanti. 



I have seen an adult male from Morocco with the moustachial 

 stripe washed with red, though not so decidedly marked as in 

 males of G. viridis, or in the Spanish race G. sharpii. Should, 

 however, this red moustache be frequent in adult males of G. 

 vaiUanii, then the Spanish and North-African "Woodpeckers 

 are not specifically separable. Anyway the subject requires 

 further investigation. 



Saxicola leucura. 



From the Black Chat's habit of nearly always constructing 

 a screen or pile of small stones in front of the nest, which ia
