16. The bird was discovered lying in the grass at the margin of 
a small lake on an island in the bay. It had so recently died 
that it was made up into a good skin. Nothing was learned as 
to the probable cause of death. The ova were small, so that if 
the bird had bred in the vicinity it must have been some time 
before. No others were seen by the party. The species is not 
known to occur regularly in summer east of the Kenai Peninsula. 
Oidemia americana Swainson. American Scoter. 
This scoter was noted in flocks of as many as two hundred in 
the vicinity of Windfall Harbor, Admiralty Island, April 17 to 
May 19, evidently in migration; and it was common at Mole 
Harbor from the latter date on to June 10. The species was 
again seen only at Glacier Bay in July where it was common. 
It is Littlejohn’s opinion that the breeding birds all passed on 
to the northward; those remaining were many of them faded 
and bedragegled in appearanee, evidently non-breeders. No signs 
of nesting were detected anywhere. No specimens were saved. 
Oidemia deglandi Bonaparte. White-winged Scoter. 
From the camp at Windfall Harbor, Admiralty Island, ae- 
cording to Littlejohn, great flocks were constantly in sight dur- 
ing the latter half of April. Males were often noted fighting 
furiously over the females. At Mole Harbor the species was still 
in evidence up to June 10. On Glacier Bay it was common in 
July, but no signs of nesting were noted anywhere. At Hawk 
Inlet, August 1 to 9, white-winged scoters were numerous but 
wild. No specimens were secured. 
Oidemia perspicillata (Linnaeus). Surf Scoter. 
For a while in April and early May this scoter was present 
at Windfall Harbor, Admiralty Island, in about as large num- 
bers as the other two species. An adult male (No. 113) was 
preserved on April 20. Stephens records it as still common at 
Mole Harbor May 19 to June 10, where a flock remained much 
of the time about a reef at the mouth of the harbor. The same 
collector noted it on Glacier Bay in July. No evidence of nesting 
in the region was discovered.
