tracts near watercourses, and spending the days generally in natural 

 hollows of trees or in dense shrubbery. Like most of the birds of 

 this family, it is nocturnal in its habits, but nevertheless sees well 

 enough, and even occasionally hunts in the daytime, especially 

 during cloudy weather. . . . 



"The flight of the barred owl ... is easy, and though quite 

 swift at times, it is perfectly noiseless. A rapidly passing shadow 

 distinctly cast on the snow-covered ground is often the sole cause 

 of its presence being betrayed as it glides silently by the hunter's 

 camp-fire in the still hours of a moonlight night. Far oftener, 

 however, it announces itself by the unearthly weird call-notes 

 peculiar to this species, which surpass in startling effect those of 

 all other owls with which I am familiar." (Bcndire.)
