THE GREY-HEADED WAGTAIL. 123 



But although the greater number of recorded 

 British specimens have been obtained in the 

 South of England, a few have been noticed from 

 time to time in Scotland, and Dr. Saxby has on 

 several occasions seen the species even as far 

 north as Shetland. Mr. Blake Knox thinks that 

 it occurs in Ireland, but that it is probably much 

 overlooked, or perhaps confounded with the 

 last-mentioned species. As it is common in 

 summer in most of the countries of Western 

 Europe, one would naturally expect to meet 

 with it more frequently at the same season in 

 Great Britain; and the increasing attention 

 which is being paid to ornithology, and espe- 

 cially to the birds of particular districts, will no 

 doubt result in the establishment of this species 

 in the list of British birds as an annual summer 

 migrant.
