194 BIRDS OF GUERNSEY. 



Island specimen killed at that time of year. 

 As this is a marsh-breeding Tern, it is not at all 

 to be wondered at that it does not, at all events 

 at present, remain to breed in the Islands, there 

 being so few places suited to it, though it is possible 

 that before the Braye du Valle was drained, and 

 large salt marshes were in existence in that part of 

 the Island, the Black Tern may have bred there. 

 I can, however, find no direct evidence of its having 

 done so, and therefore can look upon it as nothing 

 but an occasional autumnal straggler. 



The Black Tern is not included in Professor 

 Ansted's list, and there is no specimen in the 

 Museum. These are all the Terns I have been able 

 to prove as having occurred in the Channel Islands, 

 though it seems to me highly probable that others 

 occur as the Sandwich Tern, the Lesser Tern, and 

 the Koseate Tern (especially if, as I have heard 

 stated, it breeds in small numbers off the coast of 

 Brittany). Professor Ansted includes the Lesser 

 Tern in his list, but that may have been a mistake, 

 as my skin of a young Black Tern was sent to me 

 for a Lesser Tern.

 French, " Mouette tridactyle." The Kittiwake 

 is a regular and numerous autumn and winter 

 visitant to all the Islands, sometimes remaining 

 till late in the spring, which misled me when I
