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.
