Birds in Bering and Chukchi Seas — Swartz

Fig. 3. The Bering and Chukchi seas, showing 
included within this study. (Modified from Fleming 
between Point Lay and Icy Cape; another was 
seen near Chamisso Island in Kotzebue Sound. 
Fulmar (Fulmarus glacialis) 
Fulmars were seen on 11 occasions (Fig. 6), 
ordinarily as single birds. Two birds were seen 
together near Bering Strait and three or four 
near Little Diomede Island amid a large num- 
ber of alcids. Feeding concentrations as seen 
by Kuroda (1960:59) were not observed but, 
on the other hand, Fulmars were not abundant 
during any part of this voyage. Shuntov (1961: 
1063) described Fulmars as the most abundant 
bird in the Bering Sea west of the Pribilofs. 
Jacques (1930:360-361) remarked on their 
abundance near the Pribilofs and off East Cape 
but, in common with observations from the 
’'Brown Bear,” he saw them only occasionally 
in the Chukchi Sea. All the Fulmars observed 
(14 or 15) were the light phase, which agrees 
with the observations of Jacques (1930:361) 
that in the Arctic the light phase greatly pre- 
dominates. 
i Shearwaters 
Probably all shearwaters seen (Fig. 7) were 
Slender-billed Shearwaters ( Puffinus tenuiros- 
the portion of the cruise track of the "Brown Bear’’ 
et al., I960.) 
iris'), but they could not always be identified 
with certainty. It is possible that some were 
Sooty Shearwaters, though no records are 
known from north of the Aleutian Islands 
(Gabrielson and Lincoln, 1959:80-81). The 
former species, which breeds in the southern 
hemisphere, spends its nonbreeding season in 
northern waters and has been collected and 
observed as far north as Point Barrow (Gabri- 
elson and Lincoln, 1959:78). Several of the 
sightings reported here were feeding flocks, 
on one occasion near Cape Thompson compris- 
ing between 500 and 1,000 individuals. In no 
case, however, did abundance approach the 
concentrations that have been observed by other 
authors south of Bering Strait (see Gabrielson 
and Lincoln, 1959:79; Shuntov, 1961:1061- 
1062). 
Cormorants (Phalacrocorax) 
Cormorants were identified on four occasions 
(Fig. 7), chiefly within sight of nesting cliffs. 
One doubtful sighting was made near Chamisso 
Island in Kotzebue Sound. Cormorants were 
presumably all Pelagic Cormorants (P. pelagi- 
cus), but doubt exists in some cases. An obser- 
vation about 20 miles from Little Diomede
