Described by Pallas, who informs us that it is 

 extremely common in Siberia, and that its habits 

 are similar to the others of its tribe : it is rather 

 larger than, but similar to, the Yellow Wagtail : 

 the head, neck, and all the under parts of the 

 body, are yellow : the back is of a blueish ash- 

 colour: the nape of its neck is marked with a 

 dusky crescent : in other respects it resembles the 

 Yellow Wagtail. '
