Resident in lower Rio Grande Valley of Texas.
Flitting from shrub to shrub and skulking about the undergrowth, this unobtrusive, drab little bird is seldom seen out in the open. Nevertheless, it may be readily observed when it sings from an exposed perch or engages in nesting activities. It feeds on seeds, small larvae, and grubs.
4 white eggs in a domed nest made of twigs, grass, and leaves, placed low in a shrub or cactus.
