"The Hawk Owl is strictly diurnal, as much 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).
