Three eggs. Collector, Rev. I. O. Stringer. 
Barrow. 
This species is almost 
identical with the Glau- 
cus Gull, averaging per- 
haps a trifle smaller. 
Its standing as a dis- 
tinct species is still 
questioned and has not 
yet been decided satis- 
factorily. Early in June 
their nests are built on 
remote islands in Ber- 
ing Sea. These nests 
are the same as the last 
species, large piles of 
vegetation, hollowed on 
top for the reception of 
the eggs. The eggs 
have the same varia- 
tions in color and mark- 
ings as the Glaucus 
Gull. Size 3 x 2.10. 
Data. — Herschel Is., 
; placed on the ground. 
43. Iceland Gull. Larus leucopterus. 
Range.- — Arctic regions, south in winter to the Middle States, 
This Gull in appearance is precisely like the two preceding ones but is con- 
siderably smaller; 24 inches in length. A very common bird in the north, 
breeding in colonies of thousands on many of the islands. It is regarded as 
one of the most common 
of the larger Gulls in Ber- 
ing Sea and also nests 
commonly in Hudson Bay 
and Greenland, as well as 
in the Eastern Hemis- 
phere. They nest indiffer- 
ently on high rocky cliffs or 
on low sandy islands. Ex- 
oept when the eggs are laid 
in a sandy depression in 
the soil, quite bulky nests 
are made of seaweed and 
moss. The eggs are laid 
about the first of June; 
^ . , , they number two to three 
Greenish brown J 
and have a ground color 
of brownish or greenish brown and are blotched with umber. Size 2.80 x 1.83. 
Data. — Mackenzie Bay, Arctic America. June 18, 1899. Nest made of seaweed
