THE WHITE WAGTAIL. Ill 



at all ages and seasons no real difference seems 

 to exist. This has naturally raised some doubt 

 in the minds of many as to the validity of the 

 so-called species, a doubt which is strengthened 

 by the circumstance that in regard to haunts 

 and habits the two may be said to be insepa- 

 rable. 



This much, however, seems to be certain, 

 that whereas the Pied Wagtail is generally dis- 

 tributed as a resident species, migrating south- 

 ward at the approach of winter, the White 

 Wagtail spends only the summer months in this 

 country, and is then very local in its distribu- 

 tion. 



Beyond the British Islands the White Wag- 

 tail has a much more extensive range than its 

 , congeners, being found throughout the whole of 

 Europe, penetrating to the North Cape and 

 . even to Iceland, and travelling southward be- 

 yond the Mediterranean into Africa, to within a 

 . few degrees of the equator.
