210 ANNALS OF BIRD LIFE. 



Lapland. The remaining five species are all 

 stragglers from North America, and presumably 

 come by the same routes that the Sandpipers do. 

 They are the American Teal and Wigeon, the 

 Duffel-headed Duck, the Surf Scoter, and the 

 Hooded Merganser. 



Scarcely an autumn passes that does not bring 

 some of these distinguished strangers to our 

 shores ; and doubtless there are many other species 

 which pay us their uncertain visits, and remain 

 undetected. Almost every year the number of 

 birds noticed in the British Islands receives an 

 addition ; it is only fair to presume that this is 

 owing to the greater number of field naturalists 

 abroad nowadays, rather than to any increased 

 migration of these feathered waifs to our shores. 



A considerable number of these distinguished 

 visitors come to our islands on both spring and 

 autumn migration ; but as a rule most of these 

 are birds that breed north of the British Islands. 

 The Lesser Gray Shrike, the Wall Creeper, and 

 the Roller have visited us at both seasons; as like- 

 wise have the Black Stork and the White Stork. 

 The Little Crake and the Pratincole, the Black- 

 necked Grebe, and the Caspian Tern are also 

 common to both seasons ; so, too, are Temminck's 

 Stint, the Green, Wood, and Broad-billed Sand- 

 pipers, the Dusky Redshank, and some few others. 

 It will thus be noticed that most of the Passerine 

 strangers are either wanderers here in autumn 

 or in spring, few occurring at both seasons of 

 migration. These may be identified as follows :
