34 LARIDE 
275. NUMENIUS ARQUATA (Linn.). Curlew. 
A resident; some are to be seen on the coast all through the year; 
most numerous in August, both young and old birds. The breeding birds 
leave the coast districts in April. In 1882, eggs of curlew were taken on 
Scotton Common by the keeper. 
276. NumMENIus pH#opus (Linn.). Whimbrel. 
In great numbers in May, on their passage northward in the coast 
districts, and again in July and August on the return journey, but at the 
latter season the rule is to proceed directly south, travelling at a great 
height. 
Order GAVIA. Family LARIDA. 
Sub-family STERNINA. 
277. HyDROCHELIDON NIGRA (Linn.). Black Tern. 
Adults on the coast in May, moving north. In the autumn is a fairly 
regular migrant, but can hardly be called common; are generally young 
of the year at this season. 
278. HyDROCHELIDON LEUCOPTERA (Schinz). White-winged Black Tern. 
1860, Scarborough, one shot; in Mr. Edward Tindall’s collection 
[‘ Hand. Yorks. Vert.,’ p. 80]. 1867, Flamborough, an adult bird for some 
days in the spring [ ‘Birds of the Humber,’ p. 197]. 1896, Scarborough, 
one, immature, Scalby Ness, on September 26th [‘Zool.,’ 1896, p. 387], 
W. J. Clarke. 
279. STERNA casptA, Pall. Caspian Tern. 
1874, Filey, one early in September [‘ Hand. Yorks. Vert.,’ p. 80]. 
280. STERNA CANTIACA, Gmel. Sandwich Tern. 
The nearest nesting place is on the Farne Islands, where they arrive 
from the middle of May; leave again in August. I have seen hundreds 
collected on sandbanks off the LincoJnshire coast in September, on their 
southward passage. In 1875 one was shot at Filey Brigg on December 
15th [‘ Zool.,’ 1876, p. 4804]. 
281. STERNA DOUGALLI, Mont. Roseate Tern. 
A very chance visitor, is said to have been obtained both at Hornsea 
and Scarborough [‘ Hand. Yorks. Vert.,’ p. 79]. There were five or six 
pairs breeding on the Farne Islands in 1898 [‘ Field,’ February 4th, 1899, 
p. 169]. 
282. STERNA FLUVIATILIS, Naum. Common Tern. 
Arrives off the coast in April and May. Common again on migration 
in August and September, and into October. After a terrific north and 
north east gale on November 19th, 1898, several were seen off Flam- 
borough Head.
