Fuligida nyroca. 



Though somewhat resembling in colour the Pochard or 

 Dun-bird last described, the Ferruginous or White-eyed 

 Duck is at once distinguished from it by its smaller size, 

 its dark brown back, and by the centres of its secondary 

 quill-feathers being white ; forming a broad white bar on 

 the wing at all ages. The Ferruginous Duck is only an 

 irregular visitor to this country, principally in winter and 

 spring. Its occurrences in Norfolk have been more frequent 

 than in any other part of the British Islands, and Mr. J. H. 

 Gurney, jun., says that in that county it is something more 

 than an accidental straggler, although Mr. Stevenson does 

 not mention many instances, and those mostly between 

 January and April. It has also been obtained in Suffolk
