“The Snowy Owl is diurnal in its habits, but like most birds is 
more active in search of prey during the early morning and again 
toward dusk. Like many of the Hawks, it occupies a commanding 
perch for hours, watching what is going on about it, occasionally vary- 
ing the monotony by dropping on a mouse or launching out over the 
broad country, soon to return to its perch. During its southern wan- 
derings it is very partial to localities in the vicinity of water, especially 
the barren sand wastes along the seashore or extensive marshy flats 
bordering the bays and rivers. . . . 
“The flight is firm, smooth, and noiseless, and may be long pro- 
tracted. It is capable of rapid flight, and, according to Audubon, is 
able to capture Ducks, Pigeons, and even Grouse on the wing, striking 
them down after the manner of the Duck Hawk. 
“Of 38 stomachs examined, 2 contained game birds; 9, other birds; 
18, mice; 2, other mammals; and 12 were empty” (Fisher).

white, 3-7, 1*50 x 1*23. Date, Red Deer, Alberta, Apl. 16. 
“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, whicli is uttered generally while the bird 
is on the wing” (Fisher).
