HABITS. 
This beautiful inhabitant of the wooded valleys of the Rocky Mountains 
was not seen by us on our journey up the Missouri river, although it is 
probably found within the district of country we traversed. We are 
therefore unable to give any personal information in regard to its habits, 
and we find but little in the works of others.
