" Richardson's owl is a boreal species inhabiting North America 

 from the limit of trees south to the northern tier of states. ... It is 

 common throughout northern Alaska, wherever trees or large bushes 

 occur to afford it shelter. ... It is nocturnal in its habits, remain- 

 ing quiet during the day in the thick foliage of the trees or bushes. 

 In fact, its vision is apparently so affected by bright light that many 

 specimens have been captured alive by persons walking up and 

 taking them in their hands. On this account the Eskimo in Alaska 

 have given it the name of 'blind one/" (Fisher.)
