Glaucous Winged Gull (3)
1931
The immatures in a uniform dark
gray or sooty plumage still outnumber
the adults. So they may be encountered
anywhere in the harbor, scavenging
for food, they hang out in large
numbers in the lagoon (lake) just
south of town, and on the rocky beach
just west of Summer's Bay. In the
lagoon, the adults seem to congregate
in a large flock and sit out in
the middle.
Sept. 22 Unalaska The stomachs of
2083-84 contained shell fragments
and a soft leathery mollusk or two.
The shell fragments seem to link
the gull with the small piles of
shells which I have found on
the rocks coasting rocks along the
beach. Generally they have the
appearance of being regurgitated
but at times excreted. It is rarely
a mass of clam shell fragments
an eighth or a quarter of an inch
across. Perhaps it is an aid in
digestion the Commencement of food
for they have no gizzards.
