8o OUR RARER BIRDS 



I therefore call the attention of field naturalists to this 

 interesting species. It is readily distinguished from the well- 

 known Pied Wagtail by its slate-gray upper plumage. In the 

 places it frequents, in its habits, nesting economy, colour of 

 the eggs, flight, song, and call -notes, it closely resembles its 

 common ally. The White Wagtail is really the continental 

 representative of the Pied Wagtail, which, with the exception 

 of South Norway, Holland, and the north-west of France, is 

 confined to the British Islands during the breeding season.
