151. RED-NECKED GREBE. _Podiceps griseigena,_ Boddaert. French, "Grèbe 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. "Grèbe huppé."--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.
