The Ferruginous Duck is a rare visitor to the British 

 Isles, occurring chiefly in winter and early spring. 



In England, it has been met with most often along 

 the east coast. Norfolk has contributed over twenty 

 examples ; specimens have also been procured from 

 Suffolk, Cambridge, Yorkshire, Nottinghamshire, Lan- 

 cashire, Northumberland, Oxfordshire, Dorset, Devon, and 

 Radnorshire. Some two or three examples have been re- 

 corded from Scotland, about the Firth of Forth and the 

 Tay (W. Evans). 



It has been recorded on six occasions from Ireland ; 

 once from Dublin, and once from Antrim, March, 1871 ; 

 twice from Westmeath, January 21st, 1893, and January 

 18th, 1897 ; twice from the east coast, 1879 ; once from 

 the south of Ireland, November 27th, 1897 (Ussher).
