1910] Grinnell.—Birds: Alaska Expedition, 1908. 371 
Harelda hyemalis (Linnaeus). Old-squaw. 
Noted only in Cordova Bay, where several flocks of female 
or immature birds were seen near the mouth of the river. A 
specimen (no. 1122), saved by Miss Alexander, June 15, is in 
worn, dilapidated plumage, suggesting that the birds remaining 
in Prince William Sound through the summer are of impaired 
vitality or non-breeders. 
Histrionicus histrionicus (Linnaeus). Harlequin Duck. 
Seen throughout the summer in many of the bays and chan- 
nels of the Sound, where it doubtless regularly breeds. At 
Cordova Bay a flock of about twenty frequented a tide flat. 
Several similar flocks were noted around Hawkins and Hinchin- 
brook islands. On the latter a nest was found July 1 about a 
mile up a creek flowing into Northeast Bay. This nest, as de- 
seribed by Dixon, was placed in the grass that grew out from 
the roots of an upturned tree. There were two eges; but a 
later visit to the site showed it to have been devastated in the 
meantime by some animal. Near the same place a partial albino 
male was seen several times; it was mated to a normally plu- 
maged female. Rather large flocks were encountered around 
Montague Island, where, in a lagoon at Hanning Bay, a female 
with six young was reported by Heller. Observed also at Green 
‘Island, Port Nell Juan, and Valdez Narrows. A single speci- 
men was preserved (no. 1121, male adult), from the head of 
Cordova Bay. 
Oidemia perspicillata (Linnaeus). Surf Scoter. 
Observed in flocks at several of the bays. Although seen in 
each month of summer, no positive evidence was forthcoming 
as to its breeding in the region. Noted at Cordova Bay, Haw- 
kins, and Hinchinbrook islands, and at Valdez Narrows, where 
Heller secured a full-plumaged adult male (no. 1112), September 
19. Its stomach contained small mussels.
