1126). This and an accompanying individual were flying about 
a park-like meadow, where they may have been nesting. Heller 
noted one, September 9, at Ellamar. 
Rissa tridactyla pollicaris Ridgway. Pacific Kittiwake. 
Kittiwakes were first met with August 22 in the mouth of 
Port Nell Juan; an adult was secured (no. 1158). Thereafter 
the species was commonly observed. Heller records it from 
Knight, Chenega, Naked, and Storey islands, and at Ellamar; 
in Valdez Narrows it was abundant as late as September 21. 
Larus glaucescens Naumann. Glaucous-winged Gull. 
The commonest gull of the region, occurring about sand- 
spits, and at the mouths of streams, as well as along the outer 
reefs; common at Cordova, doubtless nesting near by, for eges 
were brought in by the natives, June 3 to 7. At the head of 
Cordova Bay many were observed on the mud flats at the mouth 
of the river. Around Hawkins, Hinchinbrook, Montague, Green, 
and Latouche islands the species was always more or less in 
evidence, and Heller found it conspicuously abundant at Che- 
nega, Dise, and Naked islands, and at Ellamar and through 
Valdez Narrows, up to September 21. Many were seen by him 
at the mouths of creeks at Drier Bay, Knight Island, and at 
Port Nell Juan feeding on spawn of the humpbacked salmon. 
On August 3 at Hoodoo Island, where an adult specimen 
(no. 1123) was taken, Dixon records some interesting obser- 
vations. Salmon were running up the creek. The dog salmon 
had about all spawned and the humpbacks were coming in and 
taking their places. The glaucous-winged gulls would wait 
around on the sand-bar until a salmon started to go up a shallow 
place. Then one of the birds would jab at the salmon’s eye, 
driving the struggling fish on shore, where the rest of the gulls 
helped to devour it. The bird shot had its mouth and throat 
full of salmon eggs. These must have been picked up as they 
floated over the riffles, for no freshly killed female salmon were 
seen. There were at least one hundred gulls gathered at this 
ereek, and living on salmon and salmon eggs.
