The Birds of Angmagsalik. 251. 
Angmagsalik, it has been met with at Scoresby Sound by Bay, while 
on the Denmark Expedition it was seen in about lat. 80° B. The species 
is a circumpolar one, breeds in numbers on Iceland and in north Norway. 
IVORY GULL (Pagophila eburnea Phipps). 
Ismaage. E. Gr.: Najavarsik. 
The Ivory Gull, which generally keeps to the open sea, seldom 
makes its appearance at Angmagsalik, and Petersen only mentions it 
on a few occasions. In the autumn of 1908 a number were seen close 
by the Colony. On October 23rd a number were seen by the native 
dwellings, and an old bird was shot. On October 31st an old and a young 
bird were shot at the same place, having alighted beside a piece of blubber 
which lay on the snow. November 12th Petersen again received a 
young bird. | 
The Ivory Gull is one of the most northerly breeding birds, a true 
polar species. It has been found breeding on the north coast of Green- 
land and on the east coast, where it was frequently seen right up to 
81°, and found breeding in lat. 76° N. 
In all, 4 skins have been sent home, all from the autumn of 1908. 
ARCTIC TERN (Sterna macrura Naum.). 
Havterne. E. Gr.: Imerkitalok — He who sprawls his legs. 
The Arctic Tern breeds fairly frequently at Angmagsalik, in colonies 
which often number up to a thousand birds. It only very rarely comes 
in to the Colony itself. On June 5th, 1908, Petersen writes that he has 
seen them in Tasiusak for the first time in the years he has been there. 
Its arrıval is usually about May 20th, and the eggs are laid in June. 
On June 11th Petersen relates having received eggs a few times. 
The Arctic Tern breeds everywhere on the west coast of Greenland, 
as also on the north coast. On the most northerly part of the east coast 
it was found breeding by the Denmark Expedition up to lat. 80°20’ N. 
On the whole it is a widely scattered circumpolar bird, which in Europe 
breeds everywhere in the northern areas; on Iceland it is a common 
breeding bird. 
A skin was sent home in 1895, that of an old bird in summer plumage. 
Wing 264 mm., Tail 175 mm., Tarsus 16 mm.
