Bridled Sparrow is a medium-sized, rufous-and-gray sparrow with bright white facial markings. This song, with a range restricted to a small region of southern Mexico, occurs in semiopen arid scrub, thickets, and in overgrown grassy clearings. Usually found in pairs or small groups, Bridled Sparrow spends most of its time on or near the ground, searching for seeds, arthropods, and even has been observed taking nectar from flowering trees. Very little is known about this species breeding biology. Despite its limited range and small population of less than 50,000 individuals, Bridled Sparrow has not been placed on any threatened species lists.
