occasional bird was encountered, and at long intervals, during the 

 summer. Flocks were seen at Lake Teslin, September 11, and at Fat 

 Creek (between Teslin and Gladys lakes) on September 13. On 

 September 21, my last day afield, I saw two mallards near Atlin. 



Nettion carolinense (Gmelin). Green-winged Teal 

 Seen at Car cross. May 23. About Atlin, though not common, there 

 were scattered pairs nesting in most of the marshes. More were seen 

 in flooded bottom lands of the upper portion of Otter Creek than 

 anywhere else. Flocks of nearly full-grown young were noted July 28, 

 on Otter Creek, but on August 6, at the same point, a brood of downy 

 young was seen that could have been hatched but a few days. The 

 species apparently leaves early for the south, though such late-hatched 

 young as were just mentioned must linger to a relatively late date. 

 No green-winged teal were seen about Atlin after the middle of 

 August. 



Spatula clypeata (Linnaeus). Shoveller 

 A single bird, a cripple, was seen by Brooks on a pond near Atlin 

 on June 27. At Carcross we were shown a mounted shoveller that had 

 been shot near that town. The rarity there of this species may be 

 attested by the fact that this bird had been preserved as a curiosity. 

 No one in the community knew what it was. 



Dafila acuta tzitzihoa (Vieillot). American Pintail 

 Seen at Carcross, May 22. A fairly common species about Atlin 



during the summer, and especially abundant in the swampy upper 



reaches of Otter Creek. The first young were noted on June 23, when 



two newly hatched broods appeared on Lake Como. 



I saw no pintails, definitely recognized as such, after the end of 



August. 



Marila affinis (Eyton). Lesser Scaup Duck 

 Scaups seen at Carcross, May 22, were presumably M. affinis. This 

 was the most numerous breeding duck in the Atlin region, where hardly 

 a pond could be found that did not harbor at least one scaup family. 

 Nests were built in grassy swales or marshes adjoining open sheets of 

 water. Early in June these ducks were in pairs, but by the third week 

 of that month most of the drakes were congregated in flocks by them- 

 selves, sometimes three or four birds ^together, sometimes ten or twelve.
