SOME ANIMALS OF YUKON TERRITORY 323 



habits vary to suit the mountainous country in which 

 the Yukon animal roams. 



Scattered bands, always restless, travelling among 

 mountains, always feeding and resting above timber-line, 

 are found all summer throughout its range. In the fall 

 large bands assemble far in the north and begin to mi- 

 grate southward, passing through the Ogilvies in Novem- 

 ber and December. The main band, numbering between 

 fifteen and twenty thousand perhaps more has pro- 

 vided the greater part of the winter supply of game meat 

 for Dawson and the mining camps of the Klondike. 

 After the winter hunters had disturbed this band for a 

 few years, the caribou changed their route of migration 

 farther to the east along the Peel River water-shed. In 

 March the majority return northward. Numerous other 

 small bands keep wandering about the Ogilvies during 

 the fall and winter. Formerly, during the migrations, 

 large bands of caribou crossed the Yukon River in the 

 vicinity of Eagle, but at present this habit of crossing 

 seems to have ceased. 



I have been unable to determine the limits of the 

 southern range of these caribou. Probably it does not 

 pass from the Ogilvies to the Selwyn Rockies. The 

 Barren Ground caribou range well to the south on the 

 Mackenzie side of the divide, and Mr. Keele advises me 

 that he has seen them near the head of the Pelly River. 

 A few may cross the divide in that latitude. But none 

 are found elsewhere in the Selwyns, unless very near the 

 Ogilvies.
