725a. TULE WREN. _Telmatodytes palustris paludicola._ Range.--Western United States on the Pacific coast; north to British Columbia. The nesting habits and eggs of these birds are in all respects like those of the last. 725b. WORTHINGTON'S MARSH WREN. _Telmatodytes palustris griseus._ Range.--Coast of South Carolina and Georgia. The habits and eggs of this paler form are identical with those of _palustris_. 725c. WESTERN MARSH WREN. _Telmatodytes palustris plesius._ Range.--United States west of the Rockies, except the Pacific coast; north to British Columbia. This variety is like the Tule Wren but slightly paler; its nesting habits and eggs are the same. 725.1. MARIAN'S MARSH WREN. _Telmatodytes palustris marianæ._ Range.--West coast of Florida. This species is similar to the Long-billed variety but is darker and more barred above and below. Its nests and eggs will not be found to differ materially from those of the others of this genus.

BROWN CREEPER. _Certhia familiaris americana._ Range.--Eastern North America, breeding from the northern tier of states northward; winters in the United States. These peculiar, weak-voiced Creepers are common in northern United States during the winter, when they may be seen slowly toiling up the tree trunks, searching the crannies of the bark for larvae. They make their nests behind loose hanging bark on old tree stubs, usually at low elevations, building them of twigs, bark, moss, etc., held together with cobwebs. The eggs, which are laid in May or June, are pure white, specked and spotted with reddish brown; they average in size .58 × .48. The nests are most often found under the loosened bark on coniferous trees. 726a. MEXICAN CREEPER. _Certhia familiaris albescens._ Range.--Western Mexico north to southern Arizona. The nesting habits of this brighter colored form are the same as those of the others. 726b. ROCKY MOUNTAIN CREEPER. _Certhia familiaris montana._ Range.--Rocky Mountains, breeding from New Mexico to Alaska. The eggs of this grayer variety cannot be distinguished from those of the eastern birds and the nests are in similar situations. 726c. CALIFORNIA CREEPER. _Certhia familiaris occidentalis._ Range.--Pacific coast from southern California north to Alaska. An abundant species, especially on mountain ranges, breeding behind the bark chiefly on pine trees. The eggs are not different from those of the others. 726d. SIERRA CREEPER. _Certhia familiaris zelotes._ Range.--Sierra Nevada Mountains in California and the Cascade Range in Oregon. Very similar to the last and with the same habits; eggs indistinguishable.
