BIRDS OF KOLGUEV 437 
STERNID/E 
Sterna macrura NAUMANN. Arctic Tern. 
Krashka-morskaya. 
While we were lying off the west coast of Kolguev in the beginning 
of June we saw a few of these birds. But I do not believe it nests on 
the island. We never saw an example after we landed. 
LARIDZ 
Larus affinis REINHARDT. Siberian Herring Gull. 
Tschatka (R.). 
There were always a few of these birds at Scharok. They nest on 
the low cliff, and in spite of constant robbery by the Samoyeds, manage 
to get a few young ones off. 
L. glaucus 0. FABRICIUS. Glaucous Gull. 
Morskaia Tschatka (R.). Har-ley-o (S.). 
The nests of the glaucous gulls which we visited were situated on the 
highest ridge of the outer sand-banks to the south of Scharok harbour. 
They were visible from a very long distance, and proved to be lumps 
formed of sand mixed with sea-weeds and great quantities of hydrozoa 
(sertularia and others), on which flourished arenaria peploides. The 
sand had in many cases originally collected round drifted timber, and 
the birds had taken advantage of this to raise upon it a pile some two 
feet and more in height. As the Samoyeds rob these nests constantly 
one wonders that any young get off. Hyland was so violently mobbed 
by these birds, which stooped right down at his head, that he shot 
two ‘in self-defence.’ 
Pagophila eburnea (PHIPPS). Ivory Gull. 
The ivory gull is, according to the Samoyed, a winter visitant to 
Kolguev. I picked up a wing belonging to this species.
