64 RESIDENTS AND MIGRANTS. 



The nest is recorded to have been found in Yorkshire, 

 Norfolk, and on the borders of Herts and Bucks. 



FEKRUGINOUS DUCK. Fuligula ferruginea*(Gme\m). 



A spring visitant, generally to the eastern counties 

 of England, between the Thames and the Humber. 

 The east of England would therefore appear to be 

 the western limit of its regular migration, the few 

 individuals which have been killed more to the west- 

 ward being stragglers. Mr. R. Grayf says, " I know of 

 but one instance of the occurrence of this bird in 

 any part of Scotland ; " and, according to Mr. Thomp- 

 son it has not been obtained in Ireland J. 



SCAUP. Fuligula marila (Linnaeus). 



A winter visitant. Supposed to have nested in 

 Sutherlandshire . 



The so-called American Scaup, Fuligula mariloides, 

 figured and described by Yarrell (Hist. Brit. Birds, 

 vol. iii. p. 349), is now generally admitted to be no 

 species, but a hybrid. The specimen figured by Mr. 

 Yarrell belonged to Mr. Doubleday ; and at the sale 

 of that gentleman's collection in August 1871, it was 

 purchased by Mr. Bond, in whose possession it now 

 remains. From an examination of this specimen, I have 

 little doubt that it is a hybrid between the Pochard
