 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

 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.
