68 FAUNA OF NORTH WALES 



215.— WHIMBREL. Numenius phceopus phceopus (L.). 



A passing migrant in spring and autumn ; more numerous on the west 

 than on the north coast — in spring than in autumn. 



The northward movement does not commence till quite the end 

 of April, as a rule. In the Migration Report for 1913 WTiirabrels 

 are recorded during April and May in small numbers at Bardsey, 

 Penrhyndeudraeth, and Conway ; while Dr. N. F. Ticehurst 

 observed two or three on Bardsey Island in June, 1913. Mr. 

 Cummings saw about twenty on the Dee Marshes, 7th May, 

 1911. He also noted single birds or pairs over Dinas DinUe 

 during August, 1914, and Forj^d Bay, Carnarvon in August, 

 1916. 



216.— BLACK TERN. Hydrochelidon nigra nigra (L.) 



Not uncommon as a passing migrant ; occurs chiefly over estuaries and 

 pools. 



In Anglesey Mr. King saw one over Llyn Bodgolched, north of 

 Beaumaris, 4th May, 1909, while Mr. W. Glynn Edwards saw 

 six over Presaddfed Lake. 21st May, 1909, and Dr. C. B. Tice- 

 hurst one at the South Stack on 1st June, 1909. Mr. Siddall 

 also saw one in Bull Bay, 8th September, 1909. It will be noticed 

 that all these were in the same year, as also was one which I 

 examined shot at Bettws-y-coed early in May ; this was in 

 summer plumage. On the 15th of the same month one was 

 shot at Towyn. Dr. W. G. Stone obtained one at Newtown, 

 Mont., 16th April, 1910. 



217.— SANDWICH TERN. Sterna sandvicensis 

 sandvicensis. Lath. 



Breeds in Anglesey : visits Conway estuary in spring and autumn, and 

 has been recorded on the Skerries. 



Sandwich Terns were first noted visiting the Conway estuary, 

 by Mr. R. W. Jones, May-August, 1913. Since then they have 

 occurred regularly each summer, and I have seen them as far 

 east as Prestatyn, while in June, 1918, Mr. Cummings saw 

 numbers at the west end of Menai Straits. These, doubtless, 

 come from the breeding colony in Anglesey discovered by 

 Messrs. Cummings and Oldham in 1915, and described by the 

 latter in British Birds, IX., p. 73.
