Birds of the Caucasus. 5 



PERNTS APIVORUS. 



The Honey- Buzzard is occasionally found in the Caucasus. 



BUTEO MENETRIESL, Bogd. 



This new Buzzard is a very rufous bird, with an un- 

 barred tail. It appears to be an intermediate form between 

 B. desertorum and B. ferox. It agrees with the rufous form 

 of both in colour and in the absence of bars on the tail, but 

 it is too small for the one and too large for the other. The 

 female measures 16 inches in length of wing, and the male 

 15 inches. 



BUTEO VULGARIS. 



The Common Buzzard is said only to pass through the 

 Caucasus on migration.

 ment of Stavropolsk and in the plains.
