Montana Cooperative Wildlife Research Unit 



The Montana Cooperative Wildlife Research Unit was established at Montana State Univer- 

 sity on February 8, 1950. It is operated through a coordinating committee with representatives 

 from the State Fish and Game Department, State University and U. S. Fish and Wildlife Service. 



Two new investigations were initiated by Unit personnel during this period. One study 

 delves into the ecology of the Golden Eagle while the other is concerned with movements of the 

 Northern Yellowstone Elk Herd.
