OF BRITISH BIRDS 69 



SUMMER VISITORS. 



As might be expected, there are no summer visitors to the 

 British Islands that do not visit England. They all come from 

 the south in spring, and could scarcely reach Scotland or Ireland 

 without passing the English coast. There are four summer visitors 

 which do not reach Scotland. None of these four reach Ireland, 

 and an additional species which objects to cross the sea twice raises 

 the number of summer visitors which are unknown in Ireland 

 to five. 



There are forty-eight British Birds which may be regarded 

 as Summer Visitors, though in a few species some stragglers 

 remain behind at the autumn migration and spend the winter 

 with us. 



Twenty-seven of these species are more or less cpmmon sum- 

 mer visitors to our Islands, and five others may also be regarded 

 as summer visitors to the three kingdoms, though they are rare or 

 very local in Ireland :-
