151. Clangula clangula americana. American Golden-eye. — Resi- 

 dent. In summer, not common; in winter, common; in migration more 

 common. A dozen or more of this species have been known to remain all 

 summer along the Barr Lake Chain, and for this reason I have called it a 

 resident, although I have never actually found its nest. There are no 

 hollow trees or stumps along this chain of lakes for them to nest in. I 

 have found other ducks' nests in excavations that the ducks themselves 

 had made in musk-rat houses. Following its natural inclinations for 

 hollowed-out nesting sites, this duck may do the same. 



152. Clangula islandica. Barrow's Golden-eye. — Winter resident. 

 (Nov. 18-?.) In migration, not common; in winter, not uncommon. 

 Not known to breed. 



153. Charitonetta albeola. Buffle-head. — Winter resident. (Oct. 

 24-April 25.) In migration, common; in winter, not uncommon. 



154. Harelda hyemalis. Old-Squaw. — Winter resident. (Oct. 16- 

 about March 1.) In migration and winter, rare. Cooke mentions but 

 six specimens for Colorado, all taken in or near this area. They are: 

 one found dead by G. F. Breninger on the shore of a lake near Fort Collins; 

 two shot by J. B. Sibley on McKay Lake, near Denver, Nov. 13, 1892; 

 two shot by Bryan Haywood at Calkin's Lake, near Longmont, and in 

 Weld County, Oct, 16, 1898; and another shot by Mr. Haywood at the 

 same place on Oct. 23. (Birds of Colo., pp. 57, 195.) H. G. Smith records 

 one other, shot by Judge Park at Longmont, about Nov. 20, 1903. (Auk, 

 XXV, 1908, p. 185). I have a number of other specimens to here record: 

 One, received in the flesh to mount by J. C. Miles, a Denver taxidermist, 

 on Nov. 12, 1903, was shot by D. I. Simmons, about 10 miles down the 

 Platte River from Denver; another was shot by Adolph Siebolt, who gave 

 me the note, during the first or second week in November, 1904, at Lock'3 

 Lake, one of the Barr Lake Chain; another received in the flesh by J. C. 

 Miles, Dec. 30, 1904, was shot by Mart Watrus at Kennicott Club Lake, 

 3$ miles east of Longmont; another received in the flesh to mount by 

 Hugo Todenwarth, on Dec. 4, 1905, was shot by Paul Ireland, presumably 

 near Denver; another was shot by Mart Watrus, my informant, at Kenni- 

 cott Club Lake in the latter part of February or first part of March, 1906. 

 It thus appears that seven out of the total of twelve specimens reported 

 for Colorado were taken within this area. 



[160. Somateria dressed. American Eider. — Migrant; very rare in 

 adjoining locality. Cooke records one taken by W. G. Smith at Loveland 

 some time previous to 1892. (Birds of Colo., p. 156.) He also states that 

 "there is a mounted bird of this species at the rooms of the Society of 

 Natural History in Denver .... presumably taken in Colorado nearly 

 twenty years ago." The bird herein referred to does not appear to be a 

 dresseri; in fact, Mr. Rudolph Borcherdt, who mounted it, and from 

 whom the Natural History Society purchased it, informed me that he 

 imported this skin, along with a lot of other skins, from Germany.]
