Birds of the Caucasus. 9 



PASSER SALICARIUS. 



The Spanish Sparrow is found at Lenkoran, but is doubt- 

 fully recorded from the Caucasus. 



PASSER MONTANUS. 



The Tree-Sparrow is common in many villages on the 

 Caucasus. 



PASSER PETRONIA. 



The Rock- Sparrow is found in suitable localities through- 

 out the Caucasus from the snow-line to the shores of the 

 Caspian. 



FRINGILLA CCELEBS. 



The Chaffinch is common in all the forests of the Caucasus. 



FRINGILLA MONTIFRINGILLA. 



The Brambling is occasionally found in the Caucasus, pro- 

 bably only on migration. 



FRINGILLA COCCOTHRATJSTES. 



The Hawfinch is occasionally found in the Caucasus. 



FRINGILLA CHLORIS. 



The Greenfinch, which is common throughout the Cau- 

 casus, is said by Bogdanow to be subsp. chlorotina, Licht., 

 and to differ from the typical form in having a thicker bill 

 and in being of a brighter green-colour, with the under tail- 

 coverts pure yellow. A comparison with examples from 

 Turkestan would be necessary to form an opinion as to its 

 specific distinctness. 



CARDUELIS ELEGANS. 



The Goldfinch is very common in the lower forests and 

 plains. 



SERINUS PUSILLUS. 



The Red-fronted Finch is found throughout the steppes 

 and in the rhododendron-region, descending to the plains 

 only in winter. 



CHRYSOMITRIS SPINUS. 



The Siskin breeds in the pine- and rhododendron-regions.
