GLAUCOUS GULL (Larus hyperboreus Gunn.). 
Graamaage. Е. G.: Kusek (Probably from the cry). 
The Glaucous Gull breeds fairly commonly in the district around 
Angmagsalik, and on the whole is one of the birds most frequently 
appearing and in greatest numbers; it breeds on the islets, as well as 
on the bird-cliffs, but nowhere in very great numbers. There is, however, 
a cliff in the Sermilik Fjord where there are hundreds of breeding birds. 
It is one of the few really stationary birds, as it only allows itself to 
be driven away by the ice, which makes its appearance at various times, 
but never later than the turn of the year. When there is again open 
water here and there in the fjords, in April-May, it returns. In the 
autumn, September to November, they are to be seen in numbers in 
Tasiusak close to the Colony itself, and a great many of them are shot. 
Some years they may be met with somewhat later than January Ist, 
as for instance was the case in 1908 and 1914. 
The Glaucous Gull is a true circumpolar species, is common every- 
where on the west coast of Greenland and has been found breeding all 
along the east coast up to about lat. 80° N. Some of them breed on 
Iceland, and at Spitzbergen it is a common breeding bird. 
ICELAND GULL (Larus glaucoides Meyer). 
Hvidvinget Maage. E. Gr.: Kusek (Probably from the cry). 
Petersen does not seem to separate this bird from the foregoing 
one, whereas Кмор Poursen often mentions it in the Angmagsalik 
district. 
The species is a common breeding bird in West Greenland, both 
to the south and to the north. On the east coast north of Angmagsalik 
it has only been met with more occasionally. It is principally to be 
found in the northern parts of America. 
KITTIWAKE (Rissa tridactyla tridactyla L.). 
Ride, Tretaaet Маабе. Е. Gr.: Taterak (From the cry). 
This bird breeds at Angmagsalik but only in small numbers; is on 
the whole only seen occasionally, and only in one year — 1908 — did 
it appear more frequently. On September 25th Petersen writes about it: 
“A number are seen every day in Tasiusak (near the Colony), a thing 
that has not happened before. This is of course a consequence of the 
fact that this year the sea has been singularly clear of ice.” 
It breeds in large numbers along the whole of the west coast of 
Greenland, up to the most northerly areas. On the east coast, north of
