Nettion carolinense (Gmelin). Green- winged Teal. 



First observed at Kuiu Island on April 28, when they were 

 apparently just arriving from the south. During the following 

 week they increased in numbers daily, and when we left the 

 place (May 6), they were quite abundant, usually seen feeding 

 in company with the mallards at the heads of the bays. The 

 species was not seen again until we reached Thomas Bay on 

 August 13. At this place many small flocks of six or eight 

 individuals were flushed from the sloughs and streams. A 

 few flocks were seen on the Taku River in September, but at 

 this time they were evidently leaving for the south ; one was 

 shot as late as September 26. 



Two adult females (nos. 9913, 9914), secured at Thomas Bay 

 on August 18, and in newly acquired autumnal plumage, have 

 the under parts slightly stained with rusty, in the same manner 

 as some of the water birds from the Prince William Sound 

 region, as already reported upon by Grinnell (1910, p. 365). 



Dafila acuta (Linnaeus). Pintail. 



At Kuiu Island, the only place where the species was 

 observed, a few migrating flocks were seen from April 25 to 

 May 6. 



Marila marila (Linnaeus). Greater Scaup Duck. 



Small flocks of blue-bills were seen at many of the places 

 visited. At Kake Village, on the morning of April 11, several 

 flocks were noted in the bay. At Kuiu Island, April 25 to May 6, 

 some were seen daily, usually in company with the scoters. At 

 Calder Bay, Prince of Wales Island, several flocks were seen 

 on May 11 and 13. A single drake was observed at the head of 

 Marten Arm, Boca de Quadra, on June 14; and, at Thomas 

 Bay, August 13 to 23, one or two flocks were seen feeding in the 

 open waters of the bay. 



It may be that Marila affinis also was seen, and that both 

 species are included in the above summary, for no specimens 

 were secured at any time. The blue-bills were conspicuously 

 wary and unapproachable, feeding in open water, where there
