717b. DOTTED CANON WREN. _Catherpes mexicanus punctulatus._ 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. 718. CAROLINA WREN. _Thryothorus ludovicianus ludovicianus._ Range.--Eastern United States, breeding from the Gulf to southern New England and Illinois; resident in the greater part of its range. These loud-voiced songsters are well known in the south where they are very abundant, being found along banks of streams, in thickets, along walls, or about brush heaps. They nest in almost any suitable nook or corner, in hollow trees or stumps, bird boxes, about buildings, and in brush or bushes. When in exposed positions, the nest, which is made of all sorts of trash, is arched over; the eggs, which are laid from March to June, and frequently later, as several broods are sometimes reared in a season, are white, profusely specked with light reddish brown and purplish. Size .74 × .60. 718a. FLORIDA WREN. _Thryothorus ludovicianus miamensis._ Range.--Southern Florida. A similar bird to the last but darker above and brighter below. Its eggs are not distinguishable from those of the last. 718b. LOMITA WREN. _Thryothorus ludovicianus lomitensis._ Range.--Southern Texas. This sub-species is abundant along the Lower Rio Grande in southern Texas, where its habits are the same as those of the others and the eggs are not distinctive.

BEWICK'S WREN. _Thryomanes bewicki bewicki._ Range.--South Atlantic and Gulf States, and the Mississippi Valley north to Minnesota and locally to the Middle States in the east. This species is not common on the Atlantic coast but in the interior it is the most abundant of the Wrens, nesting in holes in trees, stumps, fences, bird boxes, tin cans, etc., filling the cavities with grass and rootlets. Their eggs are laid in the latter part of April or May; they are white, specked and usually wreathed about the large end with reddish brown and purplish. Size .65 × .50. 719a. VIGORS'S WREN. _Thryomanes bewicki spilurus._ Range.--Pacific coast of California. This similar bird to the last has the same general habits and the eggs are not in any way different from those of Bewick's Wren. 719b. BAIRD'S WREN. _Thryomanes bewicki bairdi._ Range.--Southwestern United States, from western Texas to eastern California and north to Colorado and Nevada. Like the two preceding Wrens, this one nests in natural or artificial cavities, and the four to seven eggs that they lay are precisely alike, in every respect, to those of the others. 719c. TEXAS WREN. _Thryomanes bewicki cryptus._ Range.--Texas, north in summer to western Kansas. A very abundant bird in Texas. Nesting habits not unusual nor eggs distinctive.
