i8o THE PIED WAGTAIL 



boe and the grazier boier. By the ancient Romans the 

 beef market was called the forum boarium. And so 

 the name of boarule given to the Yellow Wagtail may be 

 supposed to indicate this habit of following up the cattle 

 in quest of his insect food. Bergeronette, the common 

 French name of this charming and useful species, is 

 equally descriptive of the bird as an ally of the shepherd. 



The Pied Wagtail, Motacilla lugubris, is our common 

 and well distributed species. The Grey Wagtail, M. 

 Melanope, a beautiful bird with its longer tail and yellow 

 tints, frequents our hilly districts and mountain streams ; 

 but, the Blue-headed species is only an irregular visitor 

 to our Islands, on migration. The food and habits of 

 this family are alike, and they are all most useful to the 

 grazier and farmers generally.
