Towards evening the Gulls would assemble at their roosting place 

 uttering a violent screaming and barking. At sunset they under- 

 took from here — in one flock — a detour of short duration to 

 the rocks on the West probably the nesting-places; from here they 

 returned to the sandbars, on which they spent the night. 



The young ones would at the end of August gradually go to 

 sea where they immediately mingled with the old gulls on the bar 

 without however following these on their more extensive excur- 

 sions. 



As mentioned before they were still fed by the parents for a 

 while. The majority of gulls disappeared from the country at the 

 beginning of September. 



August 1907 I visited Hvalrosodden again and found some Glau- 

 cous Gulls, but by far not so many as the preceding year. But very 

 few young ones had been hatched, and I did not see one bird of 

 the age of 1 to 2 years. The unfavourable ice conditions probably 

 account for this reduction. 



In the summer 1908 the Glaucous Gulls appeared again in nor- 

 mal numbers. 



For the zoological museum in Copenhagen were collected the 

 skins of 4 old and 1 young bird and the beforenamed two eggs.

Kittiwake. Laras tridactyliis L. 



In the country itself the Kittiwake was only observed at 

 Mallemukfjeldet and some other smaller bird cliffs lying near to 

 this between lat. 80° 10' and 80°20'n. Koch and Bertelsen counted
