According to the 4th edition of Yarrell, there is no 

 absolute proof of the breeding of this Diver in any 

 part of our islands, though there can be but little 

 doubt of its having done so in Sutherland and the 

 Shetlands. In Iceland this bird is said to be found in 

 the breeding-season upon almost every lake. With 

 regard to its nesting-habits, I must refer my readers to 

 our standard authorities. In stormy weather this Diver 

 utters a melancholy resonant moan ; but this cry I have 

 only once heard. I cannot positively assert that I ever 

 saw the Great Northern Diver in any part of the 

 Mediterranean, although it does occasionally appear in 

 the eastern portions of that sea during the winter 

 months.
