NON-INDIGENOUS BRITISH BIRDS. 349 



NONPAREIL FINCH. 



CYANOSPIZA CIRIS {Ijjl7iceus). 



One British record. A species subject to some 

 migratory movement, but, as was suggested long ago by 

 Montagu, probably an escape. Habitat : Central and 

 North America. 



^ WHITE-THROATED SPARROW. 



ZONOTRICHIA ALBICOLLIS iyGnieliu). 



Two British records. A migratory species, and the 

 date of capture (autumn) is a point in favour of the 

 individuals having reached our area by abnormal migra- 

 tion. Habitat: North America. 



* BRANDT'S SIBERIAN BUNTING. 



EMBERIZA CIOIDES CASTANEICEPS, Moore. 



One British record. A partially migratory species, 

 and the date (October) and locality (near Flamborough) 

 of the specimen are strong points in favour of the sup- 

 position that it was an abnormal migrant from the far 

 east. The specimen is said to approach most closely to 

 the Chinese, and not to the Siberian race of this species. 

 Habitat : Northern China.
