82 BIRDS. 



Scarborough, one shot ' many years ago ' by Mr. C. Watson, 

 of York (AUis, 1844). 



Filey, adult male, Aug. 1875 (Tuck, Zool., 1875, P- 4689). 

 Redcar, one shot, Nov., 1879 (Mussell, Field, Feb. 14, 1880). 

 Filey, adult male, autumn, 1880 (Backhouse, Friends' Nat. 

 Hist. Journal, 1881, p. 39). 



341. Larus atricilla Z. Laughing Gull. 



Accidental visitant from the eastern coast of North America, 

 of extremely rare occurrence. 



. Filey, adult male, March, 1876 (Tuck, Zool, 1876, p. 4960). 



342. Larus ridibundus L. Black-headed Gull. 



Resident, extremely local in the breeding season. Common 

 on the coast in early spring, late summer, and autumn ; 

 less numerous in winter. Though formerly breeding in 

 several localities, its stations are now reduced to two — a 

 large colony on Thome Waste, and a few pairs which have 

 this year (1881) revisited Strensall Common — a former 

 resort. Up to last year this bird bred plentifully on 

 Riccall Common — now enclosed, broken up, and drained. 

 Mr. F. S. Mitchell informs me that in i860 a colony 

 appeared on the shores of a tarn on Newton Fell, and 

 deposited a large number of eggs, but these being all 

 taken, the gulls left the place and never returned. 



343. Larus melanocephalus Natt Adriatic Gull. 



344. Larus ichthyaetus Pall. Great Black-headed Gull. 



345. Larus minutus Pall. Little Gull. 



Periodical visitant to the coast, in very limited numbers, in 

 autumn and winter, most frequent at the former season. 

 A female was obtained at Flamborough on the 13th of 

 July, 1868, in full summer plumage, but birds of the year 

 and old ones in winter dress are most frequent. In 

 February, 1870, after a terrific gale from the East, no less 

 than twenty-nine were obtained at Bridlington, nineteen 

 old and ten young birds. 



346. Larus Philadelphia Ord. Bonaparte's Gull.
