ocT.,iyoo.] BIRDS OF THE YUKON REGION. 63 



36. Charitonetta 'albeola. Buffle-hcad, 



I shot a fciiiiilo on a small pond near Lake Marsh July S, and saw 

 a male near Little Salmon River July 20. Maddren was informed 

 that buffle-heads were common near Miles Canyon, and a lio}^ at Lower 

 Lebarge said they bred commoidy on the ponds near there, and that 

 he took two young July 16. 



37. Harelda hyemalis. Old Squaw. 



Single young l)irds were found frequently during September in the 

 small ponds about St. Michael, and a flock of about a dozen was seen 

 in the harbor September 11. No adults were observed. One ^^oung 

 bird, taken earl}^ in September, still retained natal down on the hind- 

 neck. 



38. Histrionicus histrionicus. Harlequin Duck. 



We saw a male and two females in Wrangell Narrows May 29. A 

 flock of twelve males came close to the shore at Bennett June 18; and 

 on June 23 a single male swam so near that men sitting on the beach 

 threw stones at it. One other harlequin was seen a few miles above 

 Fort Selkirk July 25. Dr Romig told me he saw a number on the 

 portage from the Kuskokwim to the Yukon August 24-25. 



3t». Somateria v-nigra. Pacific Eider. 



We saw the head of a male of this species lying in the window of 

 the hotel at St. Michael, and the soldiers at the barracks had a 

 mounted bird, shot near St. Michael in the spring, but we saw no 

 living eiders of any species during our trip. 



■40. Oidemia americana. American Scoter. 



We noticed a few in Wrangell Narrows May 29, and I saw a number 

 ofi" Unalaska October 5. 



41. Oidemia deglandi. White- winged Scoter. 



This species was fairly numerous at Bocadequadra, Wrangell Nar- 

 rows, and Lynn Canal May 28-30. We saw two on Lake Marsh July 

 6, two on Lake Lebarge July 14, and a flock of about twenty-five flying 

 up Fifty-Mile River from Lake Lebarge on the evening of July 12. 



42. Oidemia perspicillata. Surf Scoter. 



In Lynn Canal, near Haines, June 1 we noted a large flock of surf 

 scoters, most of which had disappeared the next day. They were 

 abundant on all the Yukon lakes except Bennett, which was almost 

 destitute of bird life. On Lake Tagish we saw fourteen June 30, and 

 at Lake Marsh thirty to forty males almost every day between July 

 1 and 8. We saw no more, except a pair on July 11 on Fifty-Mile 

 River, which connects Lake Marsh with Lake Lebarge, until we
