1921 BIRDS OF MONTANA 37 



;36. Marila af finis (Eyton) 



Lesser Scaup Duck 



A common migrant lliroiighoiit the state. Breeds along the northern border 

 on the east side of the continental divide. Breeding records : Milk River (Coues, 

 1874a, p. 574); Teton County (Saunders, 1914a, p. 128). Migration records 

 are in Fergus County (Silloway, 1903a, p. 14), at Flathead Lake (Sloanaker, 

 MS) and as below. 



Migration dates: Fort Keogh, March, 1889 (Thorne, 1895, p. 212) ; Terry, 

 May 7, 1905 (Cameron, 1907, p. 249) ; Gallatin County, I\Iay 7 and 14, 1909; 

 Great Falls, May 1, 1912; Button, May 12, 1917 (DuBois, MS). 



37. Marila collaris (Donovan) 



Ring-necked Duck 



Rare migrant. At present known definitely from two localities only. Two 

 birds were taken from a flock of eight or nine on Storey Creek, near Belgrade, 

 Gallatin County, October 10, 1912, by Thomas (Saunders, 1915d, p. 238), and 

 three more Avere taken from a flock of fifteen in the same locality November 17, 

 1914 (Thomas, MS). Dr. Coues mentions a specimen of this bird in "Daw- 

 son's collection" (1874b, p. 651) but as the locality and date are unknown, it is 

 doubtful whether the bird came from Montana. This may be the same Dawson 

 who collected a specimen of the Hudsonian Godwit, "east of the Milk River" 

 and the duck may have come from that region. Reported from swampy ground 

 in Glacier National Park in summer (F. M. Bailey, 1918, p. 53).

 state, and not common there. Breeding records: Flathead Lake (Silloway, 

 1901a, p. 40) ; Lake Josephine, Glacier National Park, August 9, 1915. A few 

 pairs are believed to breed along the Yellowstone River in the vicinity of Bill- 

 ings (Thomas, MS). 



Winter records: Gallatin County (Saunders, 1911a, p. 33); Jefferson 

 County (Saunders, 1912a, p. 23) ; Teton County (Saunders, 1914a, p. 128). Win-
