Fia. 355. — Short-eared Owl, reduced. (Sheppard del. Nichols sc.) ean a. Inhabits N. Am. at large, 
and most other parts of the world. It appears to be somewhat migratory with us, and is 
sometimes seen in considerable flocks, especially in marshy places, which are its favorite 
hunting-grounds for the small quadrupeds and other animals upon which it preys. It is a 
great destroyer of shrews and field-mice, deserving on this account to be protected in the 
interests of agriculture. The nest is commonly built on the ground, sometimes in an under- 
ground burrow, consisting of a little hay and feathers; the eggs are 4—7 in number, dull white, 
roundish, about 1.55 X 1.25. This owl breeds indifferently in any latitude, and is one of those 
frequently abroad in the daytime. 
164, STRIX. (Gr. otpiy€, strigx, Lat. striz, a sereech-owl.) GRAY OwLs. Brown OwLs. 
Woop Owns. Skull and ear-parts more or less unsymmetrical, the latter large, furnished 
with a moderate operculum scarcely reaching the whole length of the opening. Head very 
large, appearing as broad as the body, and perfectly smooth, there being no plumicorns : facial 
dise complete and of great extent, the comparatively small eyes centric in the radiating feathers. 
Nostril in edge of cere, which is shorter than rest of culmen. Bill yellow; iris yellow or 
black. Tail very long, 2 to ? as long as the wings. Wings much rounded ; 4 to 6 primaries 
sinuate on inner webs; Ist quite short. Feathering of feet variable ; tarsus always feathered, 
but toes wholly or partly feathered, or naked. A large genus of ‘earless’ owls, chiefly of the 
northern hemisphere, of medium to very largest size. North America has at least three per- 
fectly distinct species; the commonest one of these, S. nebulosa, represents the European 
tawny owl, S. aluco.
