Clay-colored Sparrows are small, streaky sparrows that occur in Arizona primarily as migrants. They breed across the northern Great Plains of the United States and southern Canada, favoring shrubby grasslands, and winter in Mexico and the southern United States. In Arizona, they are most often detected during spring and fall migration, when individuals pass through brushy fields, desert washes, and woodland edges. They can be difficult to distinguish from closely related Spizella species such as Brewer’s Sparrow (Spizella breweri) and Chipping Sparrow (Spizella passerina), but the Clay-colored is best recognized by its pale gray collar, buffy face, and distinct dark eyeline and malar stripe. Although never abundant, they are regular enough that birders searching during migration periods—especially in southeastern Arizona—have a fair chance of encountering this subtly marked sparrow.
