WHISKERED TERN. 



Hydrochelidon hybrida (Pallas). 



Accidental visitant from central Europe and northern Africa, of 

 extremely rare occurrence. 



The Whiskered Tern breeds on the Spanish marshes, 

 the banks of the Danube, in south Russia and northern 

 Africa, and is found as far south as the Cape of Good Hope, 

 and eastward in Mongolia. 



The only notice of its occurrence in this county is reported 

 from Hornby Castle, the residence of the Duke of Leeds, 

 where one was shot on the river Swale by one of the keepers, 

 in 1842 (T. Southwell, Nat. 1885, p. 393). 



GULL-BILLED TERN. 

 Sterna anglica (Montagu). 



Accidental visitant from southern Europe and northern Africa* 

 of extremely rare occurrence. 



This Tern nests on the west coast of Denmark ; at the 

 mouth of the Rhone ; and on the north and east shores of 

 the Mediterranean, and the Black and Caspian Seas ; it 

 migrates to India, China, and the Eastern Archipelago. 



The only Yorkshire example is that mentioned in the 

 " Ann. and Mag. N. H." (1843, p. 297), and also referred 

 to in Allis's Report, which had been wounded, and was brought 

 alive to H. Denny in the last week of July 1843. 



Thomas Allis's Report of 1844 contains the following : 



Sterna anglica. The Gull-billed Tern H. Denny informs me that 

 a bird of this species was taken alive in a reservoir belonging to a mill 

 on the York Road, near Leeds, and was brought to him in July 1843.
