" Dr. Dall considers it a stupid bird, and states that sometimes it 

 may be caught in the hands. Its great predilection for thick woods, 

 in which it dwells doubtless to the very limit of trees, prevents it from 

 being an inhabitant of the barren grounds or other open country in 

 the north. . . . 



" The note of this Owl is said to be a tremulous, vibrating sound, 

 somewhat resembling that of the Screech Owl. . . .

" Richardson's Owl is nocturnal in its habits, remaining quiet dur- 

 ing the day in the thick foliage of the trees or bushes. In fact, its 

 vision is apparently so aifected 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.' 



" The song of this Owl, according to Dr. Merriam (Bull. Nuttall 

 Ornith. Club, vol. vii, 1882, p. 237), is a low, liquid note that resem- 

 bles the sound produced by water slowly dropping from a height "
