The sole member of the genus Oriturus, the Striped Sparrow is a distinctive, boldly-patterned, and large-bodied sparrow that is endemic to Mexico. It occurs primarily in the Sierra Madre Occidental and Trans-Mexican Volcanic Belt, where it occupies montane grasslands and meadows with tall bunchgrasses and scattered shrubs that are typically surrounded by forest. The species forages in small groups, often with one or more individuals perched atop a small tree or bush acting as a sentinel, while the rest of the flock forages among bunchgrasses. Though variable, its song is usually comprised of a distinctive series of 1–3 nasal beeping notes followed by a fast rattling trill, tiuk tiuk drrrrrrrrrrrrrrrr ; the species has a myriad of call notes that defy easy categorization. Little is known about the biology of the Striped Sparrow and research is needed on diet, habitat preferences, spatial ecology, social behavior, vocal repertoire, breeding biology, and how populations are affected by grazing and agriculture.
