ing about the marshes. The natives value them for their 

 quills^ as they use the back of the shaft to attach fishing- 

 lines to the hooks. 



Buffon's Skua. Lestris parasiticus. 



Yunge-uk, Eski.

Arrived on the 7th of May, after which some of these birds 

 were always to be found near the stages for drying fish ; here 

 they seem to live, principally by plundering them. Some of 

 them frequented the marshes, hunting about for eggs, and 

 robbing the Terns and small Gulls. They bred about the

Kok-dr-uk and Kok-d-nok, Eski. 



[Colymbus septentrionalis, Dall & Bann. p. 307.] 



The first of these birds arrived on the 21st of May; and
