rench, "Grebe
jou-gris."--I have never seen a Channel Island specimen of the
Red-necked Grebe in full breeding-plumage as I have the Sclavonian, but
it is a tolerably regular autumn and winter visitant, and in some years
appears to be the more numerous of the two. Certainly in November, 1875,
this was the case, and the Red-necked Grebe was commoner than either the
Great-crested or the Sclavonian Grebe, especially about the Guernsey
coast between St. Peter's Port and St. Samson's, where I saw several;
and a good many were also brought into Mr. Couch's about the same time
more than usual. One which I obtained had slight traces of the red about
the throat remaining, otherwise this one was like the others which I saw
in complete winter plumage.

The Red-necked Grebe is included in Professor Ansted's list, but only
marked as occurring in Guernsey. There is one specimen in the Museum.

152. GREAT-CRESTED GREBE. _Podiceps cristatus_, Linnaeus. French.
"Grebe huppe."--The Great-crested Grebe is a regular autumn and winter
visitant to the Channel Islands, but not, I think, in quite such numbers
as at Teignmouth and Exmouth and along the south coast of Devon. I have
not shot this bird in the Channel Islands myself, nor have I seen it
alive: but I have seen several Guernsey-killed specimens. These were all
young birds or adults in winter plumage; and I have one, a young bird of
the year, killed in the Guernsey harbour late in November, 1876.

It is included in Professor Ansted's list, but only marked as occurring
in Guernsey. There is one specimen, a young bird of the year, in the
Museum.

153. GREAT NORTHERN DIVER. _Colymbus glacialis_, Linnaeus. French,
"Plongeon imbrim."--The Great Northern Diver is a common autumn and
winter visitant to all the Islands, arriving early in November, perhaps
even about the last week in October. The earliest date at which I have
seen it myself was on the 9th November. A considerable majority of these
autumnal visitants are young birds of the year, the rest being adults in
winter plumage; but, as is the case on the south coast of Devon, a few
occasionally remain so late on in the spring as to have fully attained
the breeding-plumage. There is one Guernsey-killed specimen in perfect,
or nearly perfect, breeding-plumage in the Museum, which I think was
killed some time in May by Mr. Peter Le Newry, a well-known fisherman
and gunner living in Guernsey, who procured a good many specimens for
