Range. - Eastern Mexico, north to the Lower Rio Grande Valley in Texas.

This species is similar to the Parula but is more extensively yellow below, and has black lores and ear coverts. Their habits are the same as those of the last and their nests are generally placed in hanging moss, and are also said to have been found hollowed out in the mistletoe which grows on many trees in southern Texas, New Mexico and Arizona. The eggs cannot be distinguished from those of the last.
