. Birds of America;. Birds -- North America. BIRDS OF AMERICA WRENS Order Passeres; suborder Oscines; family Tr vtidcc. N the TroglodytidcE or Wren family there are over 250 different forms through- out the world, only some 30 species being represented in the eastern hemi- sphere. In the tropical part of the Americas this family is most numerously developed. Within the bounds of the United States there are twenty-eight species and subspecies, occupying nearly the whole country from the Atlantic to the Pacific. With the exception of the Marsh Wrens they all prefer some cozy nook for their homes. The natural sites are in the cavities in trees and rocks but it often happens that farm buildings afford just the place that they desire. Their nests are usually dome-shaped and the eggs are numerous, the clutches varying from 6 to 11. There are usually two broods each year. The eggs are usually white or pinkish speckled with reddish-brown but sometimes they are immaculate white or nearly uniform brown or plain greenish-blue. In plumage the sexes are alike; and the young do not differ materially,if at all, in color- ation from the adults. Red, yellow, green, blue, or other pure colors are never found. On the upper parts brown or reddish hues predominate and these are usually varied with bars, streaks, or speckles of dusky. The under parts are white, gray, buffy, tawny, rufous, or sooty or have two or more of these colors combined; these parts are rarely immaculate and usually are streaked or barred. The Wrens are small birds. Their bills are long (usually as long as the head although in some cases less) and compressed, usually slender and curved downward at the end. The bristles at the corners of the mouth are usually obsolete but frequently they are quite plain with one or two fairly well developed. The wing is rather short or very short, much con- caved underneath and much rounded. The tail varies in its relative length, sometimes shorter than the lower part of the leg; som
