NON-IiYDIGENOUS BRITISH BIRDS. 347 



ALPINE CHOUGH. 



Pyrrhocorax ALPiNUS, Kock. 



Has once occurred. A sedentary species, and known 

 to have been kept in confinement in our islands. The 

 individual probably escaped, although the date of its 

 capture (April) is one point in its favour. Habitat: 

 Mountains of Central and Southern Europe and Asia, 

 as far east as North-western China. It is recorded from 

 Heligoland.

ACELiEUS PHCENICEUS {Lt/mcCUs). 



A dozen or more British records. A migratory 

 species, but unfortunately one often kept in confinement 

 and imported freely. It is possible that some of the 

 individuals may have been abnormal migrants, but the 

 above fact taints their record. Habitat : North America, 

 up to about lat. 62^. 



^ RUSTY GRAKLE. 



SCOLECOPHAGUS FERRUGINEUS, GnicUn. 



Has once occurred. A migratory species, but as it is 

 frequently kept in confinement it is possible that the 

 individual had escaped from captivity. I have examined 

 this specimen, and must in common fairness say that it 

 bears no trace of having been in a cage. Habitat: Arctic 

 regions of America, north to the limits of forest growth.
