Range. - Northeastern Mexico and the Lower Rio Grande Valley in Texas.
The habits of the White-throated Wren are the same as those of the Canon Wren, which variety is more common and better known; the eggs of this species are not distinguishable from those of the next.
Range. - Rocky Mountain region and west to the Sierra Nevadas; north to Wyoming and Idaho and south to New Mexico and Arizona.
The Canon Wrens are uniform rusty brown all over except the large sharply defined white throat patch; the underparts, wings and tail are barred with black, and the back is specked with white. Their name is well chosen for they are found abundantly in rocky canyons, ravines, and side hills. They nest in crevices or caves among the rocks, placing their nests in small niches; they are made of twigs, leaves, grasses and feathers, and the three to six eggs, which are laid from April to June according to locality, are white, sprinkled and blotched with reddish brown and lilac. Size .72 x .52.
Range. - Pacific coast from Oregon to Lower California.
The habits and eggs of this coast form of the White-throated Wren do not vary in any particular from those of the preceding variety.
