FULIGULA VALLISNBEIA, (Wils.) Steph. 

 Canvas-back Duck, 



The breeding resorts of this celebrated and muck over-rated bird were 

 for a long time considered uncertain, and its eggs have not long been 

 known. They were discovered, I think, by the late Mr. E. Kennicott in 

 the northwest part of British America. Mr. W. H. Dall speaks of the 

 Canvas-back as breeding abundantly on the Yukon, and Dr. J. S. New- 

 berry found it "more numerous than any other Ducks" in the Cascade 

 Mountains in summer. At Turtle Mountain, in July, I saw several 

 broods of partly grown young; a number were secured, with a parent 

 bird, so that there is no doubt of the correctness of the identification. 

 In most of the region, however, the bird is less numerous than the Red- 

 head. 



FULIGULA FEEII^A AMERICAS"A, (Eyt) Ooues. 

 Eed head Duck. 



Abundant throughout, but whether breeding or not was left undeter- 

 mined. None were seen or at least recognized excepting in the migrat- 

 ing season. 



BUCEPHALA ISLANDICA, (Gm.) Bd. 

 EocKY Mountain Golden-bye. 



I was greatly interested to find this species breeding in the Eocky 

 Mountains. A brood of young, accompanied by the female, was seen 

 on one of the little side-pools, surrounded by timber, at our camp on 

 Chief Mountain Lake; the old bird and two of the young, out of five or 

 six, were secured by one of the officers of the military escort, who made 

 over the flappers to me, but seemed so disinclined to part with the old 

 one that I did not press the matter, although I greatly desired the spe- 

 cimen. This is, I believe, the first recorded instance of the occurrence 

 of the species during the breeding-season in the United States. 



List of specimens. 



BUCEPHALA CLANGULA, {Linn.) Goues. 

 Golden-eye. 



Supposed, on good grounds, to occur during the migrations, though 

 not observed, at any rate not recognized, by myself.
