INTRODUCTIOX. 



23 



By September 28 (1878) most of the birds bad left the viciuity of the Vega's quarters there or 

 were seen passing high overhead toward the southern entrance to Bering Straits, oil their way 

 south. From tliat date to October 19 an endless procession of birds moved by on this course, 

 but by November 3 even the gulls became rare. This great flight of birds came from the north- 

 west, toward the New Siberian, Wrangel, and the group of islands discovered by the Jeannette 

 party. A number of species of birds are common to both shores of Bering Straits. Species of 

 circumpolar distribution are, in a number of cases, represented by a dark form on the American 

 continent and a light one on the Old World side, nolably the Hawk Owl, Great Gray Owl. and 

 the Rough-legged Hawk.
