PLAIN TITMOUSE. _Bæolophus inornatus inornatus_. Range.--California and Oregon west of the Sierra Nevadas. This common, slightly crested Titmouse is grayish brown above and grayish white below. They nest anywhere in cavities that meet with their approval, about old buildings, in fence posts, etc., as well as holes in trees. Their eggs range from five to eight in number and are white, usually spotted with pale brownish. Size .72 × .52. Data.--Tulare Co., California, April 3, 1895. Nest in an oak tree, 32 feet from the ground, in a natural cavity of a horizontal limb; composed of grasses, feathers and fur. 733a. GRAY TITMOUSE. _Bæolophus inornatus griseus._ Range.--Southeastern United States, from Colorado and Nevada southward. The nesting habits of this gray Titmouse are just the same as those of the other. 733b. ASHY TITMOUSE. _Bæolophus inornatus cineraceus._ Range.--Southern Lower California. The habits of this variety are the same as those of the Plain Titmouse and doubtless the eggs are also. 734. BRIDLED TITMOUSE. _Bæolophus wollweberi._ Range.--Mexico north to southern Arizona, New Mexico and western Texas. This handsome species is quite abundant in the mountains of southern Arizona, and nests in woods or about ranches, lining the cavities of trees with moss, down, leaves, etc. The three to seven eggs that they lay are pure white, unmarked. Size .65 × .52. Data.--Huachuca Mountains, Arizona, April 5, 1901. Nest in the natural cavity of a live oak, 12 feet from the ground; cavity lined with bark and feathers. 735. CHICKADEE. _Penthestes atricapillus atricapillus._ Range.--Eastern North America, breeding from the Middle and Central States northward to Labrador; only migratory to a slight extent. The Chickadee is too well known to need any description; suffice it to say that they are the favorites, with everybody, among all the North American birds. They breed in holes in trees in orchards or woods, and also in bird boxes. I have found by far the greater number in decayed birch stubs. They line the cavities with fine grasses and feathers, and during May or June lay from five to eight white eggs, dotted with reddish brown; size .55 × .45.

LONG-TAILED CHICKADEE. _Penthestes ataricapillus septentrionalis._ Range.--Rocky Mountain region, north to British Columbia. This variety is very similar to the last but has a slightly longer tail and the colors are purer. Its nesting habits are the same and the eggs are indistinguishable from those of the eastern Chickadee. 735b. OREGON CHICKADEE. _Penthestes atricapillus occidentalis._
