76 FAUNA OF NORTH WALES 



Off Llandudno Mr. R, W. Jones says it occurs usually solitary 

 or in pairs. There are specimens in Chester Museum obtained 

 at Point of Air in 1888, and Flint, 1886. An immature bird 

 in the collection of Sir H. B. Robertson was obtained near 

 Pistyll Rhaiadr, 28th December, 1907 : this is a long way 

 inland, as also was one at Corwen, 8th January, 1908 {Zoologist, 

 February, 1908). 



243.— GREAT CRESTED GREBE. Podiceps crislaim 

 cristatus (L.). 



Not uncommon : a few pairs breed along the English border and in Anglesey, 

 but elsewhere it is only a winter visitor to the coasts and estuaries. 



There is practically no doubt that it breeds on Presaddfed 

 Lake, as a pair has been seen there in summer by Mr. C. Oldliam 

 and Mr. W. Glynne Edwards. A single bird was seen on 

 Nannau Lake, Dolgelley, 8th April, 1908, by Mr. C. E. Munro 

 Edwards, and an adult in breeding dress on Bala Lake, 29th 

 June, 1917, by Mr. C. Oldham. I have received many additional 

 records of this species on the sea between Llandudno and Abergele 

 in spring and autumn, while Mr. D. Witty observed it on Llyn 

 Fawnog in September and December, 1908. 



244.— RED-NECKED GREBE. Podiceps griseigena 

 griseigena (Bodd.). 



Mr. T. A. Coward (F. Fauna, Cheshire, I., 450) mentions one 

 killed on Puddington Marsh about 1853, whilst Mr. J. A. 

 Dockray has seen Grebes probably of this species on the Dee 

 estuary in winter. Mr. D. Witty saw a Grebe at Colwyn Bay, 

 2nd December, 1909, which he felt sure was of this species. 

 Rev. F. C. R. Jourdain tells me that the Brown collection of 

 skins in the Derby Museum contains a Red-necked Grebe, 

 marked " N. Wales, March, 1882 " and a Slavonian Grebe, 

 marked similarly. He believes both birds came from the 

 Conway district. 



245.— SLAVONIAN, or HORNED GREBE. Podiceps 



tturilus (L.). 



Winter visitor, not infrequent on the Merioneth estuaries ; rare elsewhere. 



Mr. R. W. Jones observed one below the Great Orme's Head, 

 24th January, 1914. Three were shot on Lake Vyrnwy in 

 February, 1912 (W. Hampson).
