both natives of North America. They differ from the other 

 Eared Owls in having the facial disk less distinctly marked, 

 and incomplete above the orbits of the eyes, and in the com- 

 parative smallness of the external auditory conch, which is 

 farther destitute of an operculum or flap. Their habits may 

 be stated as nocturnal, though not so strictly so as some of 

 the other genera, as they are not unfrequently seen abroad, 

 and in activity, before the sun sinks below the horizon ; and 

 most in the Arctic Regions (which some species constantly 

 inhabit), regularly fly in day-light during the summer 

 months. They are also observed to be less annoyed, and to 

 appear less stupified, when disturbed during the day, than 

 the true nocturnal feeders ; and to be so much upon the 

 alert, as seldom to admit of a close approach. They are 

 birds of great strength and activity, and prey upon mamma- 

 lia, birds, and sometimes fish, which they strike with their 

 talons.
