BIRD-LIFE AT SEA. 245 



very small number enter the bays. We have 

 seen flocks of these birds so migrating when 

 off Berry Head, when not a single Tern could be 

 discovered in the bay close inshore. Migrations 

 of these birds may therefore often be in progress 

 without any knowledge of the fact being obtained 

 from the land. Both Arctic Terns and Common 

 Terns so migrate. We have seen parties of both 

 species out at sea, when we have been on Berry 

 Head ; and this shows that the birds may often 

 pass along the coasts in a direct line, from 

 headland to headland, without entering the bays 

 at all. The handsome Sandwich Tern is much 

 rarer in the bay, but we have both spring and 

 autumn records. Birds of this species were 

 reported to us by a competent observer during 

 the spring of 1898. The Lesser Tern must also 

 pass the mouth of Tor Bay regularly in spring 

 and autumn, on its way to breeding stations in 

 Dorset and elsewhere. As an indication of the 

 attractiveness of this locality for birds, we may 

 mention that one or more examples of the
