A tame little Owl which sometimes may be caught in one's hand. It passes
the day in dense growth, usually evergreens. Its note resembles the
"sound made when a large-tooth saw is being filed."

SCREECH OWL

_Otus asio asio. Case 1, Figs. 13, 14_

The two sexes are alike, the two color phases
being individual and representing dichromatism.
Among animals, gray and black squirrels furnish a
similar case. The ear-like feather-tufts give the
bird a cat-like appearance, hence the name 'Cat
Owl.' The young are downy-looking creatures evenly
barred with dusky. L. 9-1/2.

_Range._ Screech Owls are found throughout the
greater part of the Western Hemisphere. Our
eastern form occurs in the eastern United States
from Canada southward. The Florida race (_O. a.
floridanus_, Case 3, Fig. 19) is smaller and of a
darker gray than the northern bird. The 'red'
phase is rare.

This, the smallest of our 'horned' Owls, is also the commonest. It lives
near and sometimes in our homes even when they are situated in towns.
Its tremulous, wailing whistle (in no sense a 'screech') is therefore
one of our most characteristic twilight bird-notes. Mice and insects
form the greater part of the Screech Owl's fare. Four to six white eggs
are laid in a hollow tree, bird-box, or similar site in April.

GREAT HORNED OWL

_Bubo virginianus virginianus. Case 1, Fig. 16_

Largest of the 'horned' Owls. L. 22.

_Range._ Western Hemisphere in many forms; our
form is confined to the eastern United States. A
Permanent Resident.

The Great Horned Owl retreats before the civilization that destroys the
forests in which it lives. In thinly settled regions its deep-toned,
monotone, _whoo-hoo-hoo-hoo, whooo, whooo_ is still a characteristic
bird voice, but most of us hear
