" The Hawk Owl is strictly diurnal, as ranch so as any of the 

 Hawks, and like some of them often selects a tall stub or dead-topped 

 tree in a comparatively open place for a perch, where it sits in the 

 bright sunlight watching for its prey. 



" Although the flight is swift and hawklike, it has nevertheless 

 the soft, noiseless character common to the other Owls ; when starting 

 from any high place, such as the top of a tree, it usually pitches down 

 nearly to the ground, and flies off rapidly above the tops of the bushes 

 or high grass, abruptly arising again as it seeks another perch. 



"The note is a shrill cry, which is uttered generally while the bird 

 is on the wing " (Fisher).
