 ROCKY MOUNTAIN MULE DEER 



{Odocoileus hemionus) 



This splendid deer is of wide distribution. In California it is found 

 in the Sierras from Kern County northward, coming to the coast in the 

 northern counties. The animals here shown were taken in Siskiyou 

 County in October. 



This is the largest of the North American deer, the adult males in 

 prime condition weighing nearly 400 pounds. 



The name "Mule Deer" is sometimes applied to this species because 

 of its long ears and its mule-like tail.
