Our field experiences wih the rock ptarmigan were productive of 

 some facts of interest. One feature of the species (one that has been 

 commented upon by others) was its irregular and local distribution. 

 A male, a single bird, was shot by Brooks near the summit of Monarch 

 Mountain, June 9. This was the only one that was seen by us on 

 that mountain during the summer, though we ascended it many times. 



On one of the ridges of Spruce Mountain, during the last week in 

 July and the first two weeks in August, rock ptarmigan were found 

 regularly and in fair abundance, every time we climbed that particular 

 ridge. On an adjoining ridge, of similar aspect, none was seen, and 

 certain other nearby mountains were also explored to no avail.
