This is a form of Yellow Wagtail found in Scan- 

 dinavia, North Russia, and Siberia, extending its winter 

 migration to South Africa, the plains of India, Burmah, 

 and the Malay Peninsula. Two specimens have been 

 reported from Penzance. 



In general appearance it is very like M. flava, but 

 has no white superciliary stripe. [O. S.]
