Range.- — Northern North America, breeding north of the United States; win- 
ters south to our border and casually farther. 
This is a dark grayish and white bird, 10 inches in length, and without ear 
tufts. Breeds commonly in the extensively wooded districts of British America, 
chiefly in the northern parts. Their three or four white eggs are usually at 
the bottom of a cavity in a tree, but occasionally the birds build a rude nest of 
sticks and twigs, lined with leaves and placed in trees at a moderate height 
from the ground. Size of eggs, 1.25 x 1.05. 
372. Saw-whet Owl; Acadian Owl. Cryptoglaux acadica acadica. 
Range.— North America, breeding in the northern parts of the United States 
and in British America, and south in the Rockies to Mexico; winters south to 
the middle portions of the United States. 
This small species (length 8 inches) is marked very similarly to the preceding, 
but the plumage is brown instead of gray. They normally nest in hollow trees, 
generally in deserted Woodpecker holes, in extensively wooded sections, and 
usually in mountainous country, especially in the United States. They have 
also been known to nest in bird boxes near farm houses and in old Crow’s nests. 
During April or May, they lay from three to six white eggs. Size 1.20 x 1.00. 
They are quiet and chiefly nocturnal birds, not often seen, and may be found 
nesting in any of the northern states.
