BIRDS 71 



F. C. RaAvliugs who showed it to me. The stomach contained 

 Sand Eels recently taken. It was beginning to moult, the 6th 

 to 9th prima,ries and two outer tail feathers being new. The 

 specimen is now in the collection of Mr. R. W. Chase. 



222.— SABINE'S GULL. Xemasabini {SAh.). 

 Rare autumnal visitor to the coasts. 



223.— LITTLE GULL. Lams minutus Pall. 



Occasional visitor, rare : has been met with on the south-west and north 

 coasts. 



224.— BLACK-HEADED GULL. Lams ridihundus L. 



Resident and common on the coasts ; several breeding colonies on inland 

 moors. 



There is a breeding colony of some 400 pairs on Presaddfed 

 Lake, Anglesey. Mr. Ruddy reports that in recent years there 

 was a colony on Llyn CyffynAvy, Flintshire, attracted thither by 

 the enlargement of the lake for water supply : the gulls were 

 destroyed by the keepers because they were supposed to take the 

 fish. Mr V. P. Lort informed me that in 1910 a breeding 

 colony had become established on the lakes at Lianllugan — the 

 first colony known in Montgomeryshire — while in May, 1918, 

 Rev. E. Lorimer Thomas noted large numbers everj^ day along the 

 Severn in the Llandinam district. At the present time I have 

 observed numbers all along the upper Severn Valley, and conclude 

 there must be another colony in the district besides that at 

 Lianllugan. 



225.— COMMON GULL. Lams canus canus L. 



Common on the coast from autum to spring, but does not breed in North 

 Wales. 



Although this Gull has never been known to breed in the district, 

 it is worthy of note that in Jime, 1908, the Duchess of Bedford 

 observed two adults and several immature birds in the neigh- 

 bourhood of Criceieth ; while on 28th June, 1913, Mr. R. W. 

 Jones saw two adults and two young on the Conway Sands. Mr. 

 Cummings saw numbers on Morfa DinUe, Carnarvon, throughout 

 August 1917, while Mr. C. Oldham has observed adults in June 

 or July at Clynnog, Foryd Bay, and Prestatyn.
