62 NOKTH AMEEICAN FAUNA. [n().19. 



another feiiialo there and caught two of her half dozen downy young. 

 Two ducks, pr()})al)ly nialkird.s, were seen on Lake Marsh eJuly 6, and 

 at Miles Canyon Maddren was informed they had been common there 

 earlier in the season. We saw several females with young in the 

 marshy ponds at the foot of Lake Lebargo July 17, a few adults near 

 the Little Salmon July 20, and a good-sized flock near Charlie Village 

 August 10. Osgood shot one near Fort Yukon August 21. 



In the large flocks of geese and ducks disturbed by the steamer on 

 the Lower Yukon were two young mallards, secured at Hendricks 

 Station August 25. Mallards were common at the Aphoon mouth 

 August 27, and we saw a few at St. Michael September 2. 



30. Mareca americana. Baldpate. 



Five ducks that I took to be baldpates were seen a short distance 

 above Fort Selkirk July 25. 



31. Nettion' carolinensis. Green-winged Teal. 



Three teal that 1 saw in the creek at Circle, August 19, were prob- 

 ably this species. Green-winged teal were common in the tundra 

 ponds about St. Michael during the first half of September, but 

 apparently did not occur after September 16. All that were taken 

 were young birds. 



32. Dafila acuta. Pintail. 



Maddren was told at Miles Canyon, July 11, that pintails were com- 

 mon, but we saw none near enough for identification until August 27, 

 when I found them abundant at the Aphoon mouth. Seven were here 

 killed by a passenger on the steamer. During September young 

 pintails far outnumbered all other ducks on the marshes and tundra 

 ponds about St. Michael. Largo numbers were killed by the Eskimos, 

 but no adults were seen. Their numbers had greatly decreased by 

 September 20. 



33. Ay thy a marila. Scaup Duck. 



We saw a flock of about a dozen adult males at Caribou Crossing 

 June 24, and another of about twenty on the Yukon, a short distance 

 above Fort Selkirk, July 25. 



31. Aythya affinis. Lesser Scaup Duck. 



We found a pair with young on a small pond at Lower Lebarge 

 July 17. Osgood secured the female. 



35. Clangula clangula americana. American Golden-eye. 



I am confident that a flock of ducks seen about 25 miles above Circle 

 August 12 were males of this species or of C. islandica.
