Clay-colored Sparrow Spizella pallida

Small, slender sparrow with short bill and long, narrow tail. Subtly patterned with pale gray and buff overall. Face usually looks crisp and clean. Most similar to Chipping and Field Sparrows, but note combination of white supercilium, plain lores, and buffy rump. Song is a series of low, insect-like buzzes. Breeds mostly in grasslands with shrubs; winters in any open, brushy, or weedy area.
