Yellow-Throat (Geothlypis Trichas Caban) a very common North American warbler. It is 5½ in. long and 7¼ in. in extent of wings; the color is olive-green above, tinged with brown on the crown; chin, throat, breast, and under tail coverts, bright yellow; abdomen dull whitish buff; broad black band on forehead, bordered behind by hoary white; in winter in the males, and always in the females, there is no black band on the forehead; the wings are short and rounded, with the fourth quill the longest, the tail considerably graduated, and the legs long and yellow. It is found throughout North America, but is most abundant in the middle states, especially in Maryland, preferring the neighborhood of swamps. The song, though not very musical, is pleasing, and from its frequent repetition forces itself on one's notice, as it hops from twig to twig in search of insects, caterpillars, and spiders, uttering its "whittititee." The nest is made on the ground, even partly sunk in it, and is occasionally covered, whence the common name of " oven bird;" it is constructed externally of leaves and grass, and lined with hair; the eggs are four to six, 5/8 by 1/3 in., white with light brown specks, and are laid about the middle of May. Its nest is often selected by the cow bird as the place of deposit for one of its parasitic eggs, which is generally hatched out at the expense of the yellow-throat's own offspring, this warbler not possessing the remarkable instinct of another noticed under Yellow Bird. In some districts it raises two broods in a season.
