Plain in plumage but distinctive in habits, the Cassin's Sparrow inhabits arid grasslands in the south-central United States and northern Mexico. Though furtive, the male performs dramatic territorial display flights while singing a sweet, far-carrying song.
Song is loud, sweet, trill followed by two short descending notes. Call note is a sharp chip.
